Mathematics is not difficult to learn. We must learn math well. First, we should listen carefully in class and cherish the class for 45 minutes. Second, the memory of the class is told after class. If it is not told immediately, the book will not ask the teacher or classmates again. Third, set the wrong questions, write all the wrong questions, and repeat them over and over again until he sees the exercise and understands it. Fourth, do your homework carefully and grasp every question. Fifth, you don't have to dig deep into a problem and choose a topic according to your own strength. As long as you can do the above, I believe your math scores will get better and better.
