When I encounter a problem in junior high school mathematics, I have no ideas, what should I do?

Because you are not proficient in using mathematical formulas, and you lack ideas, you can do some open-minded problems or games, which will help you improve your math score.

Difficult problems, to find a breakthrough to solve the problem, analyze the problem do not read all the questions and then analyze, to read a sentence to analyze a sentence, from each sentence can read out what information and additional information should be written, slowly combing.

You must memorize more formulas, improve your rational thinking ability, and after encountering a problem, you must clarify your thinking before answering.

You can find a professional teacher for tutoring, so that children can have a good way of solving problems and ideas when doing math problems.

In normal times:

When you encounter a problem, be sure to give yourself time to think. Think about it first, and if you really can't, ask your classmates or teachers for advice.

During the exam: When you encounter a question that you can't do, first determine the scope of the examination, (in fact, the problem in the exam is to combine several question types in one question) where to think, where to write, one by one to write to the middle of the paper layer by layer, (sometimes the blind cat meets the dead mouse) really.

The most important thing is to do more questions and understand the inspection points. This will be handy for the exam.

Good luck.

Let your parents encourage you.

And tell you the right result.

Ask the teacher for advice!

Use your brain, or, ask your teacher for advice.

Math problems need to be learned to extract conditions and think about what can be gained from these conditions. Take (2) as an example

Conditional extraction: is a perpendicular bisection of the zhi line to derive ae=be

daoabc perimeter = 27 deduced ac=ab=10 bc=7 Answer: s bce=be+bc+ce=ae+ec+bc=ac+bc=17 (exploit conditions and derived potential conditions).

Summary: The difficulty of complex math problems is not to give you the conditions you want to use directly, but to give other conditions that seem to be useless, and then learn to extract these conditions and derive useful conditions. You can also think about it the other way around, that is, from the problem point of view, what is needed to solve the problem, and then see how to get what you want from the known conditions.

What science learning needs is accumulation, all the learning questions can be classified into several types, and then every time you do a question, think about which type of question it belongs to, what method to use, and every time you finish it, you should classify and correct the same type of problem that you have done wrong, and there is a correction book.
