The proportion of topics selected in junior high school mathematics test questions is not very large, but we can't lose these scores, and we must ensure that these scores are all obtained. Therefore, it is necessary to master the answering skills of junior high school mathematics multiple-choice questions to help us answer better. The choice of fill-in-the-blank questions is different from that of big questions, which only seek correct conclusions and do not follow the steps.

Because the answer to multiple-choice questions is one of the four options, there must be only one correct answer, so we can use the exclusion method to exclude the answer that is easy to judge as wrong from the four options, so the remaining one is naturally the correct answer.

How to assign special values:? That is, according to the conditions in the topic, select special values that meet the conditions or make special graphics for calculation and reasoning. When solving problems with special value method, we should pay attention to selecting values that meet the conditions and are easy to calculate.

Observing and guessing ideas: This method is often used to explore regular problems in junior high school problems in recent years. The main solution to this kind of problem is to use incomplete induction to solve the problem through experiment, guess, trial and error verification and summary.

Direct solution: Some multiple-choice questions are adapted from some fill-in-the-blank questions and judgment questions. Therefore, the direct method can often draw a conclusion directly from the conditions of the stem of the question through correct operation or reasoning, and then compare it with the options to determine the options. Most of us will use this method when solving problems.

Combination of numbers and shapes: "If there is a lack of numbers, it is less intuitive, but it is difficult to be nuanced." The problem of large numbers in mathematics implies the information of shapes, and the characteristics of figures also reflect the relationship between numbers. It is necessary to reveal the abstract and complex quantitative relationship through the intuitive image of form, so as to achieve the purpose of "form helps number"; At the same time, we should use the law of numbers and numerical calculation to find ways to deal with shapes and achieve the goal of "promoting shapes by numbers" 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.
