Skills of filling in the blanks in mathematics
Math fill-in-the-blank skills:

1, graphic method: draw pictures according to the information provided by the trunk of the question and get the correct answer. First of all, know the requirements of the stem to fill in the content. Sometimes, these have some results, such as answering specific figures accurately. Unfortunately, some candidates didn't notice this and made mistakes. Secondly, if there are no additional conditions, the answer should be based on specific conditions and general laws. The implied requirements of this topic should be carefully analyzed.

2, specialization method When the conclusion of the fill-in-the-blank question is unique or the information provided in the question setting conditions implies that the answer is a fixed value, you can replace the variable uncertainty in the question with a special value, that is, you can get the correct result.

3. Combination of Numbers and Shapes For some fill-in-the-blank questions with geometric background, if we can think about shapes in numbers and help them, we can often solve problems simply and get correct results.

4. The equivalent transformation method is to equivalently transform the problem into an easy-to-solve problem, so as to get the correct result. To solve the problem of establishing constants, we can usually solve it by decomposing variables into maximum values.
