Math fill-in-the-blank questions are mostly computational (especially inferential calculation) and conceptual (qualitative) judgment questions, which can only be answered by actual calculation or logical deduction and judgment according to rules. The basic strategy to solve the fill-in-the-blank problem is to work hard accurately, skillfully and quickly. Commonly used methods include direct method, specialization method, multi-line combination method, equivalent transformation method and so on.

I. Direct method

This is the basic method to solve the fill-in-the-blank problem, starting directly from the problem setting conditions, using the knowledge of definition, theorem, nature, formula, etc., and directly obtaining the result through the processes of deformation, reasoning and operation.

Second, professional methods.

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, a special value can be used to replace the variable uncertainty in the question, that is, the correct result can be obtained.

Third, the combination of numbers and shapes.

For some fill-in-the-blank questions with geometric background, if we can think of the shape in the number and help the number with the shape, we can often solve the problem simply and get the correct result.

Fourthly, equivalent transformation method.

By "simplifying complexity and turning strangeness into familiarity", the problem is equivalently transformed into an easy-to-solve problem and the correct result is obtained. In a word, thinking from multiple angles and choosing methods flexibly are the keys to solve math fill-in-the-blank problems quickly and accurately.

Finally, remind candidates to check carefully after completing the questions. If there are any omissions or mistakes, they should do it again in a comprehensive and serious way to verify the answers. Besides, if you really can't do it, don't do it in vain. You must choose an answer.
