difficult problem
I am an ice-smart girl and a good student recognized by teachers and classmates. Although my academic performance was excellent, once, a difficult problem stumped me.
Once, I finished all my homework very early on campus. I picked up the book and began to "taste" it with relish. Watching, suddenly, I saw a question:
Xiao Ming and Xiao Lan took part in a competition, and their total score was 168. It is understood that Xiao Lan's score is twice that of Xiao Ming, 42 points less. How many points did Xiao Ming get in the exam?
I like delving into difficult problems very much. Seeing this, I am interested. I put my chin in my hands and drew a picture on the paper, but I still didn't come up with it. After thinking about it, just as I was about to ask my classmates, I suddenly had a brainwave: since it is less than twice the score of 42, isn't it twice if you add that 42? According to this idea, slowly, I solved the problem.
This incident made me understand: think hard when doing things, no problem can be difficult!
Difficult composition (2):
I learned to overcome difficulties.
When did you feel great? Of course, after some achievements, it's time for others to give you a thumbs-up and praise again and again.
I remember that in the fourth grade, when the second volume was published, there was an Olympic math competition on our campus. Ten excellent students were selected in each class, and I was chosen.
I understand that this achievement should win glory for the class, and more importantly, test my true level. So, a week before the competition, I started the "Devil" project. I carefully studied the Olympic math book my mother bought me. And review all the "new three fine gardens" that have accepted mathematics practice. Who knows that after reviewing half, I met two "obstacles". I made up my mind to cut off these two obstacles. So, I started to attack, and the first line of my formula method failed, so I used the "ultimate kill"-equation. I listed for a long time, and my brain seemed to be in the water, and I was defeated. The more I do, the more anxious I am. I feel a little flustered and can't cope. I was preparing for a truce when a solution flashed through my mind. I was like a duck to water, so I picked up the Qinglong knife and brushed it to solve it. Finally, I cut off the first roadblock. Therefore, I am full of interest and pursue my victory. I fought several rounds with the second "roadblock" and was defeated again and again. I continued to rack my brains. 10 minutes later, there is still no plan to break the enemy, and I am anxious again. I also think of a clever plan. Who knows that instead of rushing out of any "coup", I am more and more anxious. I can't take it anymore, so I have to call a truce. I stood at the window and took a deep breath. It suddenly occurred to me that I had two generals under my command, namely "the principle of equal division" and "the method of narrowing the encirclement", so I asked them to help me fight. I skillfully applied these principles, and these two generals helped me kill the second "roadblock" with their swords. I am full of confidence, and I have broken all the obstacles behind me. I am full of confidence and confidence in this competition.
Hard work pays off. Finally, after working hard day and night, I won the honorary title of "First Class"-the first prize of this exam. The students are all envious. I am filled with joy, joy and excitement. After this war, I like the Olympiad more and more, and sometimes I don't ask my counselor Zhuge Dad to give me advice and attack me, which greatly increases my Olympic level.
No pains, no gains. I often feel that I am ok. If I continue to study like this, I should have a bright future. Self-confidence and self-improvement, success will be close to you. I believe you can do it, and your future is in your hands. Seize today and you will have a perfect tomorrow.

Problems encountered
My heart is struggling when my bloodshot eyes leave from several difficult problems. What should I do? Choose a or b? My eyes gradually closed to one o'clock, and I began to become dull, and my thoughts returned to the afternoon.
At that time, I went to learn Olympic Mathematics with my classmates. The topic was difficult, but we finished it in a hurry. When we jumped up from our seats and looked at the time to leave, the teacher stopped us and came up with a math problem that had nothing to do with the information we learned that day. He also told us: "If you worked it out yourself, please choose one next time and tell me your answer. If you worked it out with the help of others, you don't have to tell me. " Choose b? You decide for yourself. "When my thoughts drifted back to this moment from the distant past, my heart struggled even more. What should I do? There is a computer in front of my desk. I can turn it on and search for the answer to this question, because it is not difficult. I thought about it all afternoon, and my determination to choose A began to waver. This idea has seriously blocked my thinking. Finally, I lost to B in my heart. When I reached for a copy of "Answers to Mathematical Problems", I suddenly saw a photo of me skateboarding. Thought of here, my hand was shocked, slowly retracted, and continued my thinking.
On a cold winter night, I solved a problem that everyone will encounter and get lost easily.

difficult problem
Although the ancients said that "where there is a will, there is a way", there is still a problem that has been bothering me since I was three or four years old. Alas, why is it so difficult?
Three or four years old: my brother grabbed me and said, "If you answer the following questions correctly, I'll treat you to candy!"! There are five birds in the tree. The hunter killed one with a gun. How many are left? " "4." I answered without thinking. My brother said angrily, "No! ? Dad? Won't the birds scare away? "
Five-year-old: When I was in kindergarten, my aunt asked me in a sweet voice, "Shoot birds in the tree." I rushed to answer, "No!" My aunt praised me for being happy, but it seems to be cold in the future.
Entrance Examination: Oh, my God! What a world this is! Let me win "Shooting Birds in the Tree" again. This time, I answered slowly: "maybe not, because of the gunshot;" There may be four, because it's a fake bird, or? Silencer gun "; Maybe, because the bird is too stupid and has ear problems ... My aunt immediately announced that I passed the exam.
Ten years old: During the Chinese New Year, my mother took me to play. I watched Shooting Birds in the Tree. Without thinking, I replied, "No, because the birds were scared away by the gunshots." I was boasting proudly about getting a gift, but my aunt said, "The correct answer is no bird hunting." I retorted, "I can do without me." There are many possibilities! " Aunt said impatiently, "Don't be paranoid! The correct answer is only? Don't shoot birds ! "
Twelve years old: My mother suddenly came into my room and asked me about "not shooting birds". I replied, "No bird hunting!" Unexpectedly, my mother said, "It's gone! Or ... "Said many possibilities.
Alas! This question is too difficult! There are five birds in the tree. The hunter shot down one. How much is left? I don't understand. You got it? What a mystery!

This problem was overcome by me
Who doesn't understand that elementary arithmetic is the most complicated in primary school mathematics? Besides, I hated mathematics from the first grade, but one day I finally found it funny.
It was Tuesday night. Teacher Chen assigned some math problems, all of which were very complicated. I worked out the first few questions, but the more I worked out, the more boring it became. By the end of the question, I could not answer anything. This problem includes addition, subtraction, multiplication and division, decimal, integer and fraction, which is really complicated. I can't figure out a clue. I used some draft papers and wanted to copy the answers at the back, but at the thought of the teacher's instructions, my hand shrank back. The ticking of the clock seems to urge me to do it quickly. What annoys me is that my mother and sister beside the TV give out exclamations from time to time. At this moment, the lotus lantern is playing, and my heart itches. I really want to see my eyes.
"clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang" Oh, it's really hard! " I said to myself, trying to turn over the answers at the back. "Don't copy the answer, you will hurt yourself!" The math teacher's serious voice rang in my ear again, and my hand shrank back involuntarily. At this moment, the picture of Zhang Xiaoli's sister teaching herself a foreign language came to my eyes. I'm too straight to move. There is a book and a mirror beside her. She looked at the words in the mirror and taught herself a foreign language. What a strong will. I looked at the clock, ah! 15 minutes has passed, I have to do it quickly. I thought for a while, and I remembered what the teacher often said: "Calculate, calculate, don't calculate, use your head and use it flexibly." This sentence inspired me. I calculated a few more articles on paper, and the topic seemed simple at once, "Yes! You can use a simple method. " I did it in a hurry and flipped through the answers at the back. "ah! That's right! " This complicated problem was finally solved by me, and I was extremely excited.
I think: no matter what difficulties you encounter in the future, you should think calmly and concentrate, so that no matter how difficult the topic is, even the most difficult thing can be overcome.
