How to improve mathematics can start with the following points:

1, do more exercises, ask if you don't understand until you understand;

2, think more, why! Why is this process?

3. If you really don't understand the problem-solving process, look at the answer first, imitate the process, copy it several times, and think while copying! (deepen memory)

4, take notes, write down the steps to do the problem, and ideas!

These are simple. I hope it works for you. This is how I used to come here!
