Methods of learning mathematics well

1. Interested in learning mathematics. Interest is the best teacher. Do anything, as long as you are interested, you will take the initiative to do it, and you will try your best to do it well. But the key to cultivate students' interest in mathematics is to master the basic knowledge and skills of mathematics first. Some students always want to do difficult problems, and when they see others taking math classes, they also want to go.

2. Have a correct learning attitude. First of all, it must be clear that learning is for yourself, not for teachers and parents. Therefore, we should concentrate, think positively and speak boldly in class. Secondly, after returning home, you should finish your homework carefully, review what you learned that day in time, and then preview what you will learn tomorrow. In this way, you will learn more easily and understand more deeply.

3. Have the spirit of "perseverance". If you want to improve your academic performance, you should do it step by step. Don't expect to learn everything overnight. Even if the progress is slow, as long as you persist, math learning will be successful! We should also have the spirit of "not ashamed to ask questions" and not be afraid of losing face.
