The math came down and I found out that I had become stupid, what should I do?

If you want to learn mathematics well and improve your grades quickly, you must first be interested in mathematics, interest is the tutor of learning, and with interest as motivation, it is easier for you to improve; In addition, the use of competition can also quickly improve your grades, such as finding a better classmate than you to compare with him, first take him as the goal to follow up, and learn his good learning methods, in this way, maybe your grades will be greatly improved Also, every time you do a type of problem, you should summarize the method of doing this kind of problem, because many math problems The ideas and methods of doing the problems are relatively fixed. Of course, you must have perseverance and perseverance, and your math results will be impressive.

Hehe, I can be sure from your question: you used to be at the top of math and can solve many intermediate and advanced problems! However, you suddenly find that you are worse than others?

Oh, and it proves that others have discovered your little secrets, and others who know what you know have learned. It's not that you're stupid anymore, it's that others have improved, and you're not so enthusiastic about math now. As long as you read the reference book once, think about the more difficult questions yourself!

If you really don't understand, just ask the teacher and figure it out!

Actually, I don't think there's much need to care, my usual math is always second in the class, and I will ask the first one for a lot ......of things, but I always have more than 10 points more than him in every big examThere are some things that you care about too much and can have the opposite effect.

1. Pay attention to listening and lectures in class, and review in time after class.

The acceptance of new knowledge and the cultivation of mathematical ability are mainly carried out in the classroom, so it is necessary to pay attention to the learning efficiency in the classroom and seek the correct learning method. During class, you should closely follow the teacher's ideas, actively think about the following steps, and compare your own problem-solving ideas with what the teacher said. In particular, it is necessary to grasp the learning of basic knowledge and basic skills, and review them in a timely manner after class without leaving any doubts.

2. Do more questions appropriately and develop good problem-solving habits.

If you want to learn mathematics well, it is inevitable to do more problems, and you must be familiar with the solution ideas of various types of questions. At the beginning, you should start with the basic questions, take the exercises in the textbook as the standard, practice repeatedly to lay a good foundation, and then find some extracurricular exercises to help you develop ideas, improve your analysis and solving skills, and master the general rules of problem solving.

3. Adjust your mentality and treat the exam correctly.

The main focus should be on the three aspects of basic knowledge, basic skills, and basic methods, because the vast majority of each exam is also basic questions, and for those difficult and comprehensive topics as an adjustment, think carefully, try to sort yourself out, and summarize after completing the questions.

Adjust your mentality, make yourself calm at all times, think in an orderly manner, and overcome impetuousness. In particular, I must have confidence in myself, always encourage myself, no one can knock me down except myself, I must have my own pride, and no one can break me.

First of all, we must remedy it according to our actual situation. If the calculation is prone to errors, you can sort out and review the basic calculation rules and calculation points, pay attention to comparison, and develop the habit of being careful. If it is easy to make mistakes in solving practical problems, you can start with the basic quantitative relationship analysis to clarify the relationship between the conditions in the problem and the problem, and classify and summarize them.

Secondly, do a good job of preview before class, mark the parts you don't understand, pay attention to the reason during class, find out the reason, and at the same time, carefully complete the homework assigned by the teacher, and ask the teacher and classmates if you don't know how to do it. There is nothing difficult in the world, only afraid of people with hearts, and accordingly, you will definitely achieve the desired effect after hard work!

Hello, high school? The study of high school mathematics is best to start from the basics, take notes carefully in class, and memorize the important knowledge points that the teacher said, after class, take a look at it more, do the questions to consolidate, the knowledge points of high school mathematics are not something we can learn once, it is necessary for us to repeat to learn, repeat to do the questions, in order to learn the basic knowledge well, the high school course is very tense, the speed of the teacher's lecture is also very fast, sometimes, students may not be able to keep up with the speed of the teacher's lecture, At this time, students need to ask the teacher more after class.

The examination of mathematics is mainly based on the basics, and the difficult problems are only synthesized on the basis of simple problems. Therefore, the content in the textbook is very important, if the knowledge in the textbook cannot be mastered, there is no capital to touch the class.

1. For the content in the textbook, it is best to preview it before class, and the targeted practice questions after class must be done carefully, not lazy, and you can also repeat the class example problems several times when reviewing after class, after all, take good class notes when you are in class. "A good memory is better than a pen". For the solution of mathematical, physical and chemical problems, it is not enough to rely on the general idea in the head, but only after careful pen calculation can we find the difficulties and master the solution method, and finally get the correct calculation results.

2. Secondly, we should be good at summarizing and classifying, looking for commonalities and connections between different question types and different knowledge points, and systematizing the knowledge we have learned. To give a specific example: in the function part of higher algebras, we learned several different types of functions, such as exponential functions, logarithmic functions, power functions, trigonometric functions, etc.

But if you compare them and summarize them, you will find that whatever kind of function you need to grasp is its expression, image shape, parity, increase and decrease, and symmetry. Then you can make the above contents of these functions in a big **, and compare them to understand and remember. When solving problems, pay attention to the combination of function expressions and graphs, and you will definitely get much better results.

3. Finally, it is necessary to strengthen after-class practice, in addition to homework, find a good reference book, and try to do as many practice questions as possible in the book (especially comprehensive questions and application questions). Practice makes perfect, so that you can consolidate the effect of classroom learning and make your problem solving faster and faster.

4. It is inevitable to make mistakes in the learning process, whether you are careless or just not, you must habitually collect these wrong questions, and each subject has an independent set of mistakes, when we review before the exam, they are the key review objects, so since you miss once, you may not be wrong a second time, only in this way you will not lose points again on the same issue.

In the little bit of life, exercise logical thinking, and a careful and rapid way of thinking mathematically. Such as: play more chess, puzzle palace; Wait.

When doing geometry problems: try to close your eyes, form a figurative figure in your mind, feel it with your heart, restore the image into language, start reasoning from one point, and when you can't push it down, take another path and think again. Exercising your mind in this way, no matter what the result is, there is always something to be gained.

When doing the algebra part, reduce the language to concise words and numbers, understand it thoroughly, clarify the relationship between the known and the known, and draw and analyze it appropriately.

In short, mathematics is to replace the world and words with manageable symbols, clarify people's thinking, and facilitate the management of thoughts.

It is necessary to learn to think objectively and diligently and profoundly in the middle and outside, to think about the objective world from a starting point in a quiet place where no one is around, to understand the laws of nature, to be diligent in analysis, to immerse yourself in it, and to immerse yourself in mathematics, which will essentially make mathematics progress, but this is in the bits and pieces of life, and it is also a long-term action.

I believe that as long as you are determined to learn mathematics well, you will eventually have a breakthrough in the day of 'accumulation'.
