1, direct method: Mathematical multiple-choice questions are a method that starts from the conditions of the questions, draws a conclusion directly through correct operation, reasoning or judgment, and then compares with the selected branches to make a choice. Solving problems in this way requires a solid mathematical foundation.

2. Verification method: it is a method of substituting the answers given in the selected branches or their special values into the stem of the question one by one, verifying whether the stem condition is met, and then selecting the selected branches that meet the stem condition. When using verification method to solve problems, the speed of solving multiple-choice questions in mathematics can be greatly improved if the replacement order can be determined according to the meaning of the questions.

3. Special case method: it is a method that uses some special values, special positions, special relationships, special graphs, special series and special functions that meet the conditions of the topic to test or reason each branch, and uses the principle that the problem does not hold in special cases and the option does not hold in general cases to judge the authenticity. When solving multiple-choice questions by special case method, the simpler the special case, the more special it is.

4. Diagram: it is a method of combining problems of numbers (such as solving equations, solving inequalities, finding the maximum value, evaluation domain, etc.). ) With some graphics, use the geometric meaning of function images or mathematical results, and use intuitive geometric property analysis and simple calculation to determine the correct answer. This solution runs through the idea of combining numbers with shapes. There are many multiple-choice questions (including fill-in-the-blank questions and analytical questions) in the college entrance examination every year, which can be solved simply and quickly by combining numbers with shapes.

5. Screening method (also known as exclusion method, exclusion method): It is a method that makes full use of the feature that multiple-choice questions have only one correct branch, starts with the branch selection, and according to the relationship between the conditions of the topic and each selected branch, through analysis, reasoning, calculation and judgment, screens the selected branch, and excludes the interfering branches that contradict the topic one by one, so as to draw a correct conclusion. The premise of using the screening method is "unique answer", that is, one and only one of the four options is correct.
