Firstly, the whole system of high school mathematics is divided into several categories, set and simple logic, function and equation, sequence and permutation combination and probability, trigonometric function and three-dimensional set, inequality. Then one by one, of course, you have to memorize formulas, kilometers and theorems. Understand the meaning, don't memorize it. As for analyzing problems, each problem will have a known condition that is very eye-catching. This is the starting point of the problem. If you find the breakthrough point naturally, you can prescribe the right medicine.

The ability to draw inferences about the topic needs to be accumulated for a long time, and the teacher should also guide it here. Now some teachers are irresponsible and leave them alone after class. At this time, students are required to have this ability themselves. Recommend a book "College Entrance Examination Becomes Famous in One fell swoop", written by Ma Gankai, vice president of Mathematicians Association, to practice the ability of drawing inferences from others in mathematics. As for the summary of wrong questions, you need to buy a thicker notebook, know where he is wrong, then how to correct it, and finally classify its problem-solving methods, so that you won't make it again next time you meet the same kind. Mathematical thinking is very important, and high school teaching is to cultivate students' mathematical thinking and lay the foundation for the university.
