I think to learn a thing well, you must be interested in it first, at least not exclusive, so I suggest you adjust your mentality first and be interested in it as much as possible. If you do it, that's good. You will learn it well.
Of course, it is not enough to just like it. Don't be afraid of it. Many students get a headache and fear when they mention mathematics. If you are afraid to touch it, how can you learn it well? I don't know your background, but what I said is one-sided. It's difficult at first, so let's start with the formula theorem in books. Any exam is inseparable from books. If you think you have fully understood this book, that's good. Be patient and don't be impatient, especially when you have just learned a new lesson. The title in the book is simple, but it is an essential process. I know many students despise it, but the simpler the exam, the more people can't do it.
When the problems in your book are solved, well, your extracurricular materials will play a role. If you are learning a new lesson, try to make the materials issued by the school first. First, the teacher will definitely check the materials sent by the school, so deal with the teacher. Secondly, why did the school order that book? Many teachers must have agreed for a long time before deciding, and it must have its merits. You must firmly believe that your teacher will not hurt you. If you have done all this and still have the energy, then you should consider finding a book to chew on yourself. If you want to find a book by yourself, you must take a technical test. You must consider many factors, such as the amount of questions and the difficulty (you must improve them appropriately, but you can't just pay attention to all the problems. The college entrance examination will not focus on problems, but choose targeted topics. You can't blindly look at what others buy and buy books that suit you. Generally, just buy one. You can't just do math all the time. You must take care of all the subjects.
If you want to review, it will be more difficult, because the new lesson should not be finished, and you must not pile up new ones in order not to forget the old ones. It is best to use the whole weekend to do it. Math scores must be accumulated by sweat and time. You should plan and arrange your time reasonably, and strive to achieve the highest efficiency in the shortest time. When you are reviewing, first of all, you should read a book. Then, because you have learned it before, you should try your best to dig out all your memories. Now, there is a summary of knowledge in the reviewed books. Close the book, fill in the blanks by heart, and the knowledge you haven't mastered is clear at a glance. Of course, you will find that the problem is very slow and the error rate is high. Even the questions I have done before will be lost. Don't be afraid, the result will be repeated.
No matter what you do, you should tick off the classic and difficult questions so that you can review them later. Repetition is important. If you have nothing to do, just turn over the questions you have checked before. Maybe you will have them in the next exam. Moreover, mathematics is very logical, and you can remember it after reading it twice, but you must learn to summarize the problem-solving methods when reading it. Don't change the numbers next time and don't know how to do it, then you will do it for nothing, and the summary is also very important ~ ~
Almost. I hope you can read it patiently. That's it. I wish you something to gain and improve after reading it.
The main thing is to do more questions, and now we should strengthen training, not just understand! The key is to master!
First, pay attention to the lecture in class and review it in time after class.
The acceptance of new knowledge and the cultivation of mathematical ability are mainly carried out in the classroom, so we should pay attention to the learning efficiency in the classroom and seek correct learning methods. In class, you should keep up with the teacher's ideas, actively explore thinking, predict the next steps, and compare your own problem-solving ideas with what the teacher said. In particular, we should do a good job in learning basic knowledge and skills, and review them in time after class, leaving no doubt. First of all, we should recall the knowledge points the teacher said before doing various exercises, and correctly master the reasoning process of various formulas. If we are not clear, we should try our best to recall them instead of turning to the book immediately. In a sense, you should not create a learning way of asking questions if you don't understand. For some problems, because of their unclear thinking, it is difficult to solve them at the moment. Let yourself calm down and analyze the problems carefully and try to solve them by yourself. At every learning stage, we should sort out and summarize, and combine the points, lines and surfaces of knowledge into a knowledge network and bring it into our own knowledge system.
Second, do more questions appropriately and develop good problem-solving habits.
If you want to learn math well, it is inevitable to do more problems, and you should be familiar with the problem-solving ideas of various questions. At the beginning, we should start with the basic problems, take the exercises in the textbook as the standard, lay a good foundation repeatedly, and then find some extracurricular exercises to help broaden our thinking, improve our ability to analyze and solve problems, and master the general rules of solving problems. For some error-prone topics, you can prepare a set of wrong questions, write your own problem-solving ideas and correct problem-solving processes, and compare them to find out your own mistakes so as to correct them in time. We should develop good problem-solving habits at ordinary times. Let your energy be highly concentrated, make your brain excited, think quickly, enter the best state, and use it freely in the exam. Practice has proved that at the critical moment, your problem-solving habit is no different from your usual practice. If you are careless and careless when solving problems, it is often exposed in the big exam, so it is very important to develop good problem-solving habits at ordinary times.
Third, adjust the mentality and treat the exam correctly.
First of all, we should focus on basic knowledge, basic skills and basic methods, because most of the exams are basic topics. For those difficult and comprehensive topics, we should seriously think about them, try our best to sort them out, and then summarize them after finishing the questions. Adjust your mentality, let yourself calm down at any time, think in an orderly way, and overcome impetuous emotions. In particular, we should have confidence in ourselves and always encourage ourselves. No one can beat me except yourself. If you don't beat yourself, no one can beat my pride.
Be prepared before the exam, practice routine questions, spread your own ideas, and avoid improving the speed of solving problems on the premise of ensuring the correct rate before the exam. For some easy basic questions, you should have a 12 grasp and get full marks; For some difficult questions, you should also try to score, learn to score hard in the exam, and make your level normal or even extraordinary.
It can be seen that if you want to learn mathematics well, you must find a suitable learning method, understand the characteristics of mathematics and let yourself enter the vast world of mathematics.
You must try to do it yourself. It will be difficult at first, but you must stick to it, and it will get better after a while. You must remember the most basic formula.
The main thing is that you should not only understand but also think more about the problem. Secondly, you should do the problem well, not too much.
1, pay attention to your usual study.
In order to improve the exam results, we must change the wrong concept of "emphasizing exams over peacetime".
First of all, we should pay attention to the daily math class, actively attend classes and take the initiative to learn. We should digest teachers' explanations, questions, blackboard writing and classmates' speeches, actively and boldly participate in discussions and even arguments, and dare to put forward our own unique ideas, viewpoints or questions, so as to improve the learning effect of each math class.
Secondly, we should conscientiously complete the classroom homework and daily homework. In addition to finishing homework on time and in quantity, we should also pay attention to the quality of homework, so as to write carefully and accurately. If you can treat every assignment as an exam and every exam as an assignment, then your exam results will be satisfactory.
2. Pay attention to the process of acquiring knowledge.
In order to improve the level of mathematics, we must change "emphasizing conclusions and neglecting exploration;" The wrong idea of attaching importance to law and neglecting innovation. In the usual learning process, we should seriously experience the whole process of acquiring knowledge, such as how concepts are abstractly summarized and how formulas are derived, so that we can know "what" and "why" and "why do we do this". Through personal participation and experience in the process of acquiring knowledge, we can cultivate our ability to analyze and solve problems, and then master scientific learning methods and improve self-study ability.
3. Pay attention to the cultivation of ability
To improve one's mathematics level, one must change the wrong idea of "emphasizing scores over abilities".
For every student, the score is only temporary, and the ability is with you all your life, so you should pay attention to the cultivation of ability in your usual study to prevent rote memorization. We should learn to analyze and solve problems, and pay attention to the accuracy, profundity, extensiveness and flexibility of thinking. At the same time, we should consciously cultivate our adaptability, reverse thinking ability and creative ability, and appropriately increase the training volume of some variant questions and reverse thinking exercises.
4. Pay attention to the cultivation of study habits.
The quality of examination results depends not only on the mastery of knowledge and ability, but also on whether students have good study habits and psychological quality.
Good study habits should be not only the habit of listening to lectures and doing homework carefully, but also the habit of self-study.
Only by listening carefully and doing homework in class can we not adapt to the fierce social competition. We should also actively read some extra-curricular books to enrich our mathematics knowledge and develop our thinking. Conditional students can do some extracurricular exercises appropriately and selectively. You can also do some targeted "intensive training" according to your "weaknesses" to make yourself not weak or even strong and improve your overall level; Or according to your hobbies, you can selectively do some "upgrading training" that can activate your thinking and improve your skills, stimulate your interest and improve your competitiveness. As the saying goes, "a fist cannot leave its mouth." If conditions permit, it is still of great benefit to do some extracurricular problems properly, selectively and pertinently under the premise of "not increasing the excessive academic burden"
Examination is also a science, involving all aspects, such as having a good habit of examining questions, knowing how to calculate and checking carefully. At the same time, having a healthy body and mind is also a necessary condition for getting excellent exam results. These aspects must be paid full attention to by teachers, parents and students.
Don't think about anything else, as long as you set a special day as the starting point of your efforts and devote yourself to mathematics.
First, pay attention to the lecture in class and review it in time after class.
Second, do more questions appropriately and develop good problem-solving habits.
Third, adjust the mentality and treat the exam correctly.
In mathematics, you shouldn't be intimidated by those difficult questions. First of all, you should lay a good foundation. If you find it difficult, start with the basics and start with simple topics, such as after-school exercises. To lay a foundation, you should be familiar with the basic knowledge points, problem-solving methods and skills in textbooks. These can be consolidated through practice.
Second, when your basic knowledge is solid, you can attack with moderate difficulty, which is actually a question of skilled application of basic knowledge.
Third, difficult questions will test your ability.
Math exams lead to high scores. One is sea training, which many people say, but the effect is still good. One is to make your test strategy according to the type of test paper.
We should thoroughly understand the concept of textbooks, dig deep into the existing knowledge as far as possible, and try to solve problems by ourselves. Even if we don't do it, we should accumulate our own ideas for solving problems and cherish them.
There is no need to engage in sea tactics, but some typical questions should be done.
In short, we should have the courage and determination to challenge difficult problems and master knowledge flexibly.
I was like this at that time. Anyway, I began to review, and the rest is to do the questions. At that time, I was absorbed in reading, and I understood everything in the book, because the book is the most basic, and I believe you must understand it. Then I finished the exercises in the book and didn't have to do anything else, but I had to do some exercises in the book and I had to understand them, so I couldn't ask them quickly. After I understand them, I don't need to pick difficult problems.
After intensive training, we should start to make a set of comprehensive papers and set a time, just like an exam. You should do it yourself in a way similar to an exam. Do what you can first and never give up in the end. Make at least 2 sets a week, and make sure that each set is completed with high quality. If so, I think your math is not much worse, because in fact, the real college entrance examination is still the most basic score, accounting for 70%. The real problem is only 10% at most, so don't panic if you know it. If you can't do it, you can't do it. What's the big deal, right? Only a few people got full marks.
Lenovo, this is my understanding of mathematics.
I boast that there is no math problem that I can't do, and I don't even care about the Olympiad, because I can answer almost any problem in an instant (except the Olympiad) by association.
Needless to say, basic knowledge is necessary, but how can these basic knowledge play a good role? Lenovo!
My math is very biased. You can get full marks in math and fail in other subjects. At school, I can make up the math class I didn't take in a short time!
The most important thing in mathematics is formula. This formula must be kept in mind. Don't bother. Mathematical formulas are really hard to remember. Do more questions after that. Doing problems is the greatest help for you to remember formulas and how to use them well!
As for mathematics, I don't have much learning experience, only three points, but I think these three points are very important. If I do well in the exam, there is no problem in math at all.
First, the concept must be clear. It's easy to do this. Just read a book. Unfortunately, many people seldom turn to math books for help. They don't read books because they don't think there are many things in them. They just have classes and do problems. In fact, this is very inefficient. We must spend time reading books before class and read them again before doing homework after class. If there is a reference book summarizing concepts, you must read it after you finish your homework.
Second, we should do more questions, as everyone knows. But as for how to do it, many people are not clear. First of all, I said, do it after reading the book. You must do it in one breath. If not, leave it until this sub-topic (such as the multiple-choice part) is finished. The problem should be solved on the same day, not for a week at the latest. Most importantly, if you have a poor foundation and little energy, don't ask blindly.
The most important thing is to reflect. You should learn to summarize the questions. Generally, teachers come to class according to different types of questions. If you can't sum it up, I recommend two good reference books to you.
One is that the content is very detailed. Then there is Tianjiao correspondence counseling (I am not an advertisement), which is a correspondence course. Each correspondence course has a detailed classification of questions. If you have a poor foundation, you can look at the classification of questions before doing them, which will improve your speed. You can learn about this correspondence course from www.qiaoxue365.com.
Third, the most important thing is to recite. Don't think that you don't have to memorize science things. You must recite anything in any subject, or you will get poor grades. The concepts and formulas of questions in mathematics must be memorized, and must be memorized! !
The above is my personal experience, absolutely original! I wish you good grades!
I used to be bad at math, so I can say that my foundation was particularly poor. I failed the math exam for the first time. Only five people in our class failed. At that time, like you, I could understand what the teacher said in class. I was in a hurry when I did the problem, and I didn't know where to start. However, my math teacher told me a sentence that completely changed me. What he told me was: "Listen to the teacher."
This sentence sounds simple, but it is not so easy to practice. Listen to me slowly.
At that time, only one in our class failed, so I took one. I felt very inferior. After the exam, the teacher said, make a wrong book after class and I'll check it next class. But I forgot it after class, and I didn't remember it until the teacher checked it next class. Maybe I can tell. He happened to spot check our row. When I arrived at my apartment, I blushed and told the teacher that I forgot to write. The teacher said, "You didn't do well in the exam this time, did you? It doesn't matter. Try harder next time, you know, if you want to study hard, you have to listen to the teacher. "
I remembered this sentence: "Listen to the teacher".
I will pay special attention to what he said in the future. He asked me to do the wrong exercise book, and I did it seriously. He asked us to do exercise books, and I did it seriously. He said that I would listen carefully. Although I hated mathematics at that time, I was afraid at the sight of mathematics. But I forced myself to do it. Basically, I remember all the questions the teacher said in class clearly, and I remember the formulas and skills more clearly, even every word the teacher said in class. To do this, you must listen carefully in class.
After a while, the next exam ended, and I got 1 13.
My grades have improved and my confidence has improved a little. I'm not so afraid of math, and I feel fun when I do it.
In the future, I will study mathematics more actively and be more interested in learning.
The teacher said: We must pay great attention to basic methods and skills. You must be familiar with the knowledge in the textbook. Don't make mistakes in the missed questions.
In high school, I didn't do anything except the questions assigned by the teacher, and I didn't read so many kinds of reference books. I only read the book and did the questions required by the teacher, and my math score was above 140.
I didn't do very well in the college entrance examination, but I also answered 130.
In college, math is still very good, and the score is above 95 every time (100).
I am very grateful to my math teacher.
I hope you can also benefit from it.
I've always been good at math, and I think it's mainly doing.
1, do exercises.
2. Be sure to have a revised version and analyze your own mistakes.
3. Be sure to form your own ideas. There are many solutions to a problem, but only one is suitable for you. Don't pursue a problem. You will know several solutions. Finding your own is the most important thing.
4, mathematics must think with your head.
5. Do the questions carefully, don't just use your head and don't write.
Listen carefully in class.
When you come back, copy what the teacher said in class and do it again.
Then do after-school exercises.
Finally, buy more books and practice more.
If you can't do it again, recite the topic.
Mathematics is nothing difficult to learn. After understanding the knowledge, practice more and summarize more.
There is also the need to persevere from now on!
Science, practice is very important, and doing more practice is of great benefit to you!
Secondly, read more examples, what the teacher said in class and exercise books, look at other people's ideas, remember the general ideas of some questions, and improve quickly!
Finally, form your own methods of learning mathematics, your own study habits, and make a systematic plan.
The most important thing is: believe in yourself.
I am a student who has just finished the exam, and my math scores are fluctuating. When I summed up my experience, I found that it is not that the more questions I do, the better, but that I should do them as well as possible. After each problem, I will sum up what kind of problem this problem belongs to, and will it happen again?
Solve the problem, then do the next one seriously, step by step, and you will find a new "continent".
Pay attention to basic knowledge and grasp teaching materials. Do some representative exercises and pay attention to summing up.
Old people often say that "Chinese should be learned and mathematics should be practiced". I think this is enough to meet your requirements for improving your math scores.
I remember that before the college entrance examination, I did many questions to deepen the memory of mathematical formulas, improve the application ability of formulas and have a deeper understanding of mathematics.
All right, come on! Improve your math level!
straightforward procedure
You memorized every example in the textbook until you closed your eyes.
Don't underestimate these examples.
If one day you can solve every problem in the textbook quickly, congratulations.
Reciting mathematics is also very important. Examples help you remember formulas and understand them.
If you don't understand, strengthen your memory, and you will understand slowly.
I was not good at math before. I just finished the college entrance examination and have a deep understanding. Math, there is no shortcut! Study hard. Study hard in the second half of senior three, and the score is above 120. You are only a sophomore. Actually, there is no need to worry. There is a long way to go. The future is entirely in your hands!
I repeat, if your math teacher is not particularly annoying, you must try to like him/her and make him/her like you. Harmonious relationship is a magic weapon! I used to benefit from it. )
Study hard! You can do it! Wish you success! ! !
Fortunately, you can understand the teacher's explanation, but there is no good way to do math except to do more problems, accumulate more problems, and exercise your divergent thinking ability and fast and accurate calculation ability! Just content with listening in class, there is no shortcut to mathematics! I hope you can be admitted to a satisfactory school next year!
You have nothing to worry about! When you understand the knowledge of the textbook, do the questions at once. The more you do, the better! As long as you can do it, I can guarantee that your math score is definitely not a problem! !
You should solve the problem from the purpose of the problem, and apply formulas and known conditions to discover new conditions.
Let me give you some ideas of my own:
1: The most important thing is to improve your interest in this course.
From now on, we should lay a good foundation of mathematics. Without certain basic knowledge, how can I improve if I want to improve?
3. Just adjust your mentality, have confidence in learning this course, and think with positive thinking instead of pessimism and negativity.
4. Make a clear study plan, and strengthen your belief in learning this course well with a positive learning attitude.
In short: if you want to do one thing well, attitude is the first thing, because attitude determines everything. Then lay a good foundation, have the necessary self-confidence, motivate yourself with positive thoughts, and finally pay the sweat. If you can correct your learning attitude, I believe you can succeed. Remember: Attitude is everything. If you think you can do it, you can. Encourage yourself with positive words and never say anything that will dampen morale! ````````` I wish you success ~ ~
I think your math scores should be very good. The key is to listen carefully in class, really master the knowledge points in class and answer any questions.
& lt I can understand what the teacher says in class every time, but I don't know how to start every time I do my homework or exam. & gt 1. Your teacher said that you should not only understand this level. Teachers must know how each step comes from, what formula is used, and so on. If you don't know how to get stuck in class, you can't think for long. Because the teacher is in class with the whole class, you won't follow the teacher because you are waiting for you. Ask your classmates or teachers after class. Every time you come down like this, you will find yourself improving a lot. Everyone knows how to do math, and do more problems that are appropriate to their current level. But if doing a problem is a problem, you can't do it for the sake of doing it. Think for yourself, and don't just tell yourself that you won't do it for the time being. After reading the answer, I really can't figure out what to think at every step. Why don't I?
My experience is to thoroughly understand the textbook exercises and do simple exercises after class. After all, any basic exam questions account for 70 points.
If the foundation is not good, then we should mainly read the textbooks, master the mathematical formulas in the textbooks, do more problems, don't rush to get high marks, and start with the after-school problems, mainly to master the problem-solving methods.
Hello, I hope my experience can help you, because I was a sophomore. I think the most important thing to improve math performance is to grasp the foundation, which is the most important. Without this premise, it is best not to do the problem blindly. Secondly, we should pay attention to the key points that the teacher said in class, and we must use exercises to consolidate the key points. But the exercises are not done well enough, so we must pay attention to digestion, and quantity is second. In fact, most math problems are similar. Finally, digestion and absorption, especially after understanding, should be repeated to make it become muscle memory on the basis of repeated understanding. I encourage everyone to have a revised version of the wrong question, which has a very good effect and I have benefited a lot from it.
Finally, I hope you can conquer math and improve your grades! Do math must be repeated, repeated understanding, repeated thinking! Be sure to think more about yourself, ask fewer people, and don't ask for help when you still have a glimmer of hope to succeed!
Remember it as much as possible.
Next time you see a similar problem, you can solve it.
I can see that you are a man of ideas.
This method is recommended to you.
Really useful
Be sure to try.
For the college entrance examination
It's worth suffering.
Oil; Fuel filling; Make greater efforts
See what you want to do in class today before class. Pay attention to what you don't understand in class and draw what you don't understand. Don't recite some rules, because I didn't recite them when I was at school. Yes, I like math very much. I just want to be interested in this course. Don't take it as a course that is more difficult than anything else. Do more questions and then check. I don't understand them. There will be bread, and so will milk. If the pressure is too great, it will be harmful to your health. I'm just, I was under a lot of pressure during the senior high school entrance examination. Later, I especially loved headaches, and now I still do. I can't cure them. Now I have a headache when I am tired, and I can't think too much. By the way, I want to strengthen nutrition and eat more brain. That's all! It's up to you. Work hard, come on, and you will succeed!
Now that the college entrance examination is over, there is no need to answer this question. If I had seen it earlier, I would have given you a definite answer.
My primary school math teacher told me that the fundamental reason for not learning math well is that you don't like math at all. The indirect reason is that you don't like Chinese and don't know what good math will do you. I have never looked at mathematics correctly.
For a simple example, since you have time to post this question online. Why did you post it online? You proved that you like surfing the Internet, hoping to get an answer from others. This is desire. When you like math, you will take the initiative to find it, hoping to find the so-called "answer".
The real reason why you don't like math is to ask yourself.
Mainly the adjustment of mental stress, only a question-and-answer attitude and a calm mood can be done well. Later, in mathematics learning, high school relied on doing more problems. After proficiency, the speed of doing problems will be significantly improved, so that exams will be free and grades will naturally improve.
Everyone's learning methods are different. Let me introduce some experiences, hoping to help you reference and find your own methods:
I. General principles:
(1) Use good steel on the blade, not "useless".
1. Pay attention to what is important, what is not important, and what will not be tested at all.
2. Find out your strengths and weaknesses, where you need to make great efforts to make up for it, and where you have great potential, so that you can improve your grades quickly without spending too much time.
3. It is whether the learning method is effective. If a method doesn't work, we must try to change it.
(b) Informal, pragmatic and clear priorities
Get the maximum benefit with the least investment.
1. Take notes, for example, mainly for review. Write down what you don't understand and ask the teacher in time after class. Write down the important places, turn them over often when you have nothing to do, take them out for reference when you can't do the questions, and take them out as good materials when you need to summarize them.
Use a larger notebook and leave more space between the theme and the right side of the notebook. You can supplement it with new content. Don't spend too much time on the format, which will affect the efficiency of class.
2. For example, exercises: doing homework, taking exams, and solving problems when concepts are unfamiliar should be detailed. Skilled topics, simple drawing, just straighten your mind.
3. Thinking method
There are three common reasons why we can't solve the math problem. One is that the concept is not well understood, the other is that the mathematics feels bad, and the other is that the intermediate conclusion is not clearly remembered.
The concept and theorem of (1)
It is best to understand thoroughly and have an intuitive impression. There are two ways to improve the understanding of concepts:
1. Usually ask the teacher, "Why can you come to such a conclusion?" "Why do you think of this theorem?" .
If you don't understand these theorems well, remember them firmly. The best way is to work out the topic and accumulate experience.
Attend a course
You can give priority to listening, preview before class and pay attention to understanding, but you should practice in time when you are impressed, preferably within half a day.
You can also focus on memory, take more notes and review more.
(B) the feeling of mathematics
For example, when solving solid geometry, the whole figure can come to your mind quickly, so it is easy to connect with various theorems and figure out how to make auxiliary lines.
Practicing more at ordinary times, especially asking teachers and classmates why and listening to other people's ideas, will be very enlightening to you. If you accumulate more, you will have a good impression on mathematics.
But cultivating feelings is a slow process, so we should also pay attention to induction in learning, and pay attention to what kinds of questions, ideas and problem-solving routines are available.
(3) System analysis
In the process of solving problems, we should always know what conditions we know, what conclusions we have drawn and what we need to know, so that the analysis will not be without direction.
Fourth, ask for help and take the initiative to go first.
Take the initiative to find a teacher, just say that math is in a hurry and ask him how to learn. Teachers are generally willing to help such students.
During the summer vacation, you might as well analyze your previous papers and look at the real questions of the previous college entrance examination (don't look at the simulation questions, some of which are rare and outrageous, which is a great blow to self-confidence). Find out your weakest link and make a targeted assault.
I also communicate with the teacher at ordinary times to see what he thinks.
Verb (abbreviation of verb) about practice
The tactics of asking questions about the sea are necessary, but the quality of doing questions is more important.
(1). reference book
Reference 1: To make a book, it should be authoritative, moderately difficult and not too big in title. It is best to publish it in coastal areas. Finish it from beginning to end. The steps of disintegration need not be written, but every question should be made clear.
Reference 2: 1
