And according to the different characteristics of various related mathematical problems, it is specifically and classically introduced as follows.

Close the problem-solving skills of algebra and geometry in junior high school, such as how to evaluate algebra and how to factorize it.

Decomposition, how to prove conditional identities, how to solve problems with Vieta theorem, how to solve problems with collocation method,

How to solve problems with undetermined coefficient method, how to prove fixed value problem and maximum value problem, and how to use indirect method.

Prove several problems, how to solve problems by reduction to absurdity, how to solve multiple-choice questions, etc. , quite useful to readers.

Inspiration can receive the effect of analogy.

Go to Xinhua Bookstore, there should be something for sale!

My suggestion: Be clear-headed and cheerful when answering questions. Therefore, before answering questions, you must be good at your emotions and master your own strength, which is almost enough. (This is my personal experience)
