1, learn the most basic content, that is, the concepts and definitions in the textbook. If you don't even know the concept, don't say doing the problem. This is a very important point, you just need to understand it.

2, learn to use knowledge, which is very important. Every math problem is like this. Only by combining what you have learned can you solve a problem, which depends on your thinking. When doing math problems, we should be comprehensive and have a holistic view.

3, that's an application problem. When you do a math problem, you must look carefully. If you can do it, it is not worth it, because you didn't apply and made a mistake.

This is the experience that I have spent many years summing up. I wish you success!
