What should I do if I can't do big math problems?
You can't do big math problems, so you can deal with them like this:

First, break the whole into parts, disperse the answers, and take all the steps.

Many candidates have formed a thinking habit: I have to write the correct answer to score. In fact, this idea is wrong. Math exams, especially big questions, have scores for every step of each question. As long as you write one of the steps correctly, you can score.

So my advice to candidates is: separate the steps of solving each problem and write out the steps you can write step by step. Whether the final answer is correct or not, the score of each step has been obtained. This is called "getting points skillfully on big questions".

Second, jump to answer questions, use them flexibly and write a few questions.

Many candidates often encounter such a situation: they are stuck in the first question of a big question and can't write any more. This actually affects the thinking and scores of candidates.

At this time, candidates can skip the questions they can't answer and answer the second and third questions instead. And when answering, candidates can use the conditions of the first question to answer the second question, not too solid. Candidates can admit the intermediate conclusion first, and push it back, which will have unexpected gains. If there is enough time, candidates can go back and solve the first question.

Third, reverse thinking and the combination of numbers and shapes often have miraculous effects.

This is a way to solve the problem. There are some big problems in mathematical proof that can't be solved by thinking. Candidates can consider reducing to absurdity and using reverse thinking to solve it. Breakthrough progress can often be made.

In addition, the combination of numbers and shapes is a very effective method to solve some big problems of solid geometry. Candidates can draw numbers on the draft paper and then mark the corresponding numbers, which can help candidates solve problems more intuitively.

Fourth, discuss in categories and answer each situation comprehensively.

Some math problems are answered in more than one way, but candidates often ignore them, resulting in losing points. When candidates encounter such questions, they need to make a comprehensive analysis of the questions, so as to exhaust every situation, list every situation, answer them step by step, and then make a comprehensive induction to get the final answer.
