First, the direct method. The method of drawing correct conclusions directly through calculation or reasoning is called direct method. Just do it directly, which is the least skillful method, but you will do it most of the time.

Second, the special value method. If the selection object of the question is given for the general situation, you can choose appropriate special numbers, special points, special series and special figures to test the conclusion and make a correct judgment. For the topic under discussion, you can substitute the corresponding special value and combine the exclusion method.

3. Exclusion method. This method refers to eliminating obviously wrong conclusions one by one through reasoning or calculation, gradually narrowing the selection range, and then comparing them. It is important to eliminate the wrong answers first, so that the range of choices is narrow.

Verification method. This method refers to the method of substituting each option into the stem one by one to verify and get the correct answer. In fact, this method is essentially the same as the special value method, that is, substitution verification.

5. The combination of numbers and shapes. This method can solve the problem intuitively. Function-related problems can be solved by drawing.

6. Reasonable guessing method. If it is really impossible, then make a bold guess and combine the special value method.

Summarize the multiple-choice questions you have made, why you are wrong, which methods you can use to solve them, and consider whether there are other simpler ways to do the right thing. This can improve the speed and accuracy of doing problems. Sum up more experience.

I believe you will gain a lot by strengthening this for a week. Come on! !

This method refers to the use of non-strict logical reasoning according to the conditions of the topic and personal mathematical experience.
