& lt2> Cultivate logical thinking in solving problems and know where to start.

Start with conditions: understand the function of conditions in the topic and its function, and quickly infer the conclusions and results that can be drawn from it. Then, combined with the parallel conditions, we can draw further conclusions and finally solve the problem.

Starting with the result: when the function of the condition cannot be determined, we can consider starting with the result. First of all, we should combine the unconditional part of the topic and think of the possible necessary conditions for reaching this conclusion. Then advance to the original conditions given by the topic and solve the problem.

(3) Cultivate good mathematical spirit

First of all, on the basis of the conclusion and answer, carefully understand the problem-solving process and whether you really know the conclusion. If you don't understand, don't be happy with the answer you got. You should answer or ask your teacher or classmate again. Every step is required to have a rigorous derivation basis, or a theorem or axiom, and it is never taken for granted. If you don't ask, this is very important for learning math. To cultivate good mathematical spirit, we must ask more questions.

< 4 > Choose a topic with moderate difficulty for self-training.

There are two requirements for the selection of exercises: breadth and longitude. According to the textbook knowledge and the content of the teacher's lecture, it is a good time-saving method to sum up the key points of study, listen to the teacher and watch the students do it. At the same time, it is required to take care of all the knowledge points learned and practice every knowledge point. If the knowledge points are relatively simple, you can choose exercises with relatively high difficulty. Correspondingly, if it is difficult, you can choose exercises with moderate difficulty. It is unnecessary and difficult, so practice more.

Classical exercises always contain more knowledge points, which requires the solvers to have strong comprehensive ability and mathematical thinking, and be good at using conditions. It's not very difficult, but it requires strong insight and decision-making ability, and at the same time, it promotes the conclusion conditions, and then meets somewhere to solve the problem.

〈5〉 Cultivate interest in mathematics

Actually, it's not. Anyone should look at the whole world with suspicion. Don't doubt your different opinions. If you still have objections after your own judgment, you should bravely raise them, and don't give up your opinion because of one or two mistakes. This is not only the focus of solving problems, but also the focus of cultivating good living habits. There is no doubt that there is no innovation.

Many students are not interested in mathematics because they didn't do well in the exam, so they deny themselves and even give up mathematics. Therefore, we must have a correct view of examination. It's just a way for teachers and classmates to test their learning situation. Where they fail, they will stand up. Careless or not, it doesn't matter. Carelessness is generally due to the fact that good habits are not formed at ordinary times, so it is inevitable that the thinking is not concentrated during the exam and it is easy to answer without careful thinking. Another point is easier, as long as you spend more time reviewing, you can prevent it from happening again. As long as you develop good mathematical spirit and thinking, you can give full play to your skills in the exam.
