Learn math well:
1, get into the habit of previewing. This is a good way for me to study mathematics for many years, because I know what I can't do by learning what the teacher should say first in advance, and I have a focus when I study. Of course, it would be better if you taught yourself completely.
2. Do exercises with the book. Preview is not an end. If you have time, you can do examples and exercises after class and check the preview. If you can explain everything, you can learn it. Even if you can't, you can listen to the teacher again.
The step is to do the homework assigned by the teacher and do it carefully. When you do it, you can write the problem-solving process directly next to the topic, such as multiple-choice questions and fill-in-the-blank questions, because there are many blanks to write in the solution. The advantage of this is that the teacher can keep up with the ideas when talking about the topic, and it is not easy to get distracted.
4. The method of math grading is to master some math problem-solving ideas. Many problems in mathematics are fixed or have multiple solutions. Everyone should be good at finding and summarizing, such as induction, classified discussion and so on.
The way to learn math well is "practice". When encountering a puzzle, a scholar usually thinks for a day or two, but the method of learning crispness is swept away, and the difference is obvious, which is also the reason for poor grades.
