Now I think the reason why I can't figure it out is because you don't have this method in your math system, that is to say, you haven't done enough problems and your thinking is not systematic enough, so it's hard to think about the direction and how to solve such problems.

Probably from four aspects: preview, class, review and homework:

It is necessary to preview, draw the key knowledge, and some knowledge needs to be memorized in advance, so that you will be much more skilled in doing problems in class.

Don't be busy taking notes in class, just copy everything on the blackboard, just like me, but listen carefully to what the teacher thinks and how to solve it. If you don't understand, ask after class quickly. Be cheeky.

Review the examples in class and review them every day, otherwise you will forget that the topic you think you will do is actually nothing. Pay attention to the details and logic of the answer, and the writing must be standardized. It will help you think and help you not to be deducted. The details are easily deducted by the teacher! ! ! .

If you do your homework, don't just think. When you finish writing, you must think about what kind of topic this is. What other topics have you done are similar to it. Have you mastered its methods and characteristics? Take it out and think about it when you have time. If you do more and do it smoothly, your ideas will naturally come out.

Finally, let's cheer together. . . I didn't realize the fun of mathematics until the summer vacation. . . Senior one has passed, and it's already late. . . Work hard in Grade Two!
