If you want to get high marks in mathematics, it is very important to brush the questions, but mathematics is not a subject that can get high marks only by brushing the questions. Brushing the questions is just a process, a process of combining theory with practice, and a process of deepening your understanding of the basics by brushing the questions. The purpose is to strengthen your grasp of the basics. The key is to keep thinking, reflecting and summing up. However, when most students study formulas and theorems, they just memorize them by force and don't really understand them. This is also related to the teaching of high school mathematics. They often understand formulas and theorems by doing problems.
Everyone has the impression that they are exposed to a new knowledge point. How is the topic done? When you first come into contact with new knowledge, you must be puzzled and can't do anything. Of course, I will look at the examples in the textbook and see how the examples are solved step by step. Then I have a general idea in my heart. I need to do this when I encounter such a problem. Then I will imitate the solution of the example step by step, and I will gradually master the solution of the example.
In order to make many students understand the steps of solving problems, examples will of course be very simple, but there will be various problems in the future, and the solution of examples is not enough to solve these problems. What should we do is to turn these slightly more difficult problems into examples. For example, when I first started learning mathematics, I only knew the addition and subtraction within 10, and later I changed it to the addition and subtraction within 100. What should I do at this time? Of course, I changed the addition and subtraction within 100 to 10.
