1, the mathematical foundation is very important. The characteristic of this course is too strong inertia. Every knowledge point is like every step when we go upstairs. Failure to learn a knowledge point well is like missing a step. Some students said that I can understand what the teacher said in class. Why can't I do the problem? This is because the teacher said in class that it is like going up the stairs with the light on. Although there are one or two steps (as long as you are not used to it), doing homework or exams is like turning off the lights and going up the stairs. No one can help you point out where there are no steps, so it's strange not to fall when you walk to the broken steps. What about this situation? The only way is to make up the missing steps. The way is to take time to look at the previous textbooks. If you still can't understand an old textbook, it means that what you want to make up is still ahead. Put this book down for the time being and look at the older textbooks. Until you can fully understand it, then look back from this book until you study the textbook now. Personally, I think this is much more important than doing homework to complete the task, which is the fundamental guarantee for you to keep up with the course. I have a granddaughter, that's all. Once she asked me a math problem with four knowledge points. When I asked her, she couldn't answer any of them. I told her to look at the corresponding part of the previous textbook before doing this problem, but she asked her classmates. Of course, the result is nothing more than copying the answers and finishing her homework. She also said that I am not as good as her classmates, and I only have a wry smile (here I can't help complaining about the current education, homework, homework, and evil, which is a rope to hold good students and a rope to hold poor students' necks. I often couldn't finish my homework at that time. . . In my opinion, it is much more important for so-called poor students to spend time learning what they forgot before than doing their homework. Of course, I'm not here to tell you not to do your homework, but to spend appropriate time making up lessons for yourself.

2. To learn math well, interest is the most important thing. Everyone says so. But in the final analysis, only when you have a good foundation can you be interested. It is impossible for a person to be interested in what gets him into trouble. Therefore, students with poor grades should spend more time on the first step. If you are a middle school student, you should be able to read primary school textbooks. You can understand that you must find it interesting to do some Olympic math problems in primary schools. This can cultivate your interest in mathematics. What can you do if you have fun?

3, mathematics is not by rote, but by understanding, how to understand, or on the basis, so students with poor grades should spend more time in the first step. As for the memory of formulas, you only need to remember the most basic ones, and the rest you can learn to deduce by yourself. Inventors can't remember many formulas in those days, but I can deduce the formulas I need on the spot in a minute or two in the examination room, which is much safer and absolutely accurate than memorizing them by rote. It's called understanding memory. Inventors have been out of textbooks for twenty or thirty years, but the formula I need to do the problem can still be deduced according to its definition. The so-called good steel is used in the blade, which is what it means. Don't spend your time on meaningless things. Rote memorization is not reliable. Problems are most likely to occur at critical moments. If you can't remember it at once, or you are not sure about a symbol, the problem is over, but it is different if you can deduce it yourself. You just need to remember a few formulas in a book. I'm afraid there won't be more than 20 formulas to remember from elementary school to high school. For example: area formula, just remember the area formulas of rectangle and circle. Rectangular area = base x height (S=ab). How to deduce the triangle area from this? Draw a diagonal line in a rectangle, will you get two triangles with the same area? Sure: (S=ab/2) What about the trapezoid? Draw a diagonal line in the trapezoid. Are there two triangles? And they are the same height? According to the triangle area formula, there is S=ah/2+bh/2=(a+b)h/2. One thing to say is that you can use special circumstances when deriving the formula, because you are not proof. Inventors have not touched textbooks for many years and know nothing about textbooks. If there are problems, we can discuss them together and make progress together.

4, do more questions and think more, in order to open the thinking surface. Above all, I am against doing homework, not telling you not to do homework, but wasting your time doing homework that at first glance makes no sense to you. You should use this time to do real problems. If you really think that doing homework is a waste of time, you can apply to the teacher not to do it. I think the teacher should agree (your current teacher should be much more open-minded than our teacher at that time, right? )

When encountering a good topic, we should think about one more question: that is-how did this topic come into being? Can you think of a similar problem, a different problem, or an improvement problem? In this way, the next time you encounter this problem or similar problems, you can easily solve it. This is also a good way to train divergent thinking. It is also the most important way of thinking for inventors.

6. Listen carefully, and ask teachers or classmates questions in time if you don't understand them. Confucius is not ashamed to ask questions until he understands them, let alone us! 7. Self-confidence is very important. You must believe that you can succeed. I don't want to talk nonsense. Finally, I hope you fall in love with math, so you will find it interesting. Still worried about not learning math well?
