Common methods to solve multiple-choice questions include combination of numbers and shapes, logical exclusion, verification one by one, estimation and judgment, direct answer and so on. There are many methods, and students should learn to use them flexibly and classify them to improve their ability in this respect. The following mainly introduces several common problem-solving methods of multiple-choice questions.

1, direct method

Starting directly from the conditions of the topic, using the knowledge of related concepts, properties, theorems, rules and formulas, through strict reasoning and accurate operation, the correct conclusion can be drawn. Direct method is the most commonly used basic method to solve multiple-choice questions, and low-level multiple-choice questions can be solved quickly by this method. The direct method has a wide range of applications, and as long as the operation is correct, the correct answer will be obtained.

2. Exclusion method

Starting from the conditions of topic setting, this paper deduces by using theorems, properties and formulas, and gradually eliminates the interference term according to the instruction of choosing one from four, so as to get the correct judgment. The screening method is suitable for qualitative or multiple-choice questions that are not easy to solve directly. When there is more than one condition in the topic, first find out the obvious contradiction in the selected branch according to some conditions and deny it, and then find out the contradiction in the narrowed range of selected branches according to other conditions, so as to gradually screen until the correct choice is obtained.

3. Number-shape combination method

According to the conditions of the topic, make the curve or related figure of the studied problem, and make the correct judgment with the intuition of geometric figure. It is customarily called the combination of numbers and shapes. It is very simple and effective in solving multiple choice questions.

4. Valuation method

Because multiple-choice questions provide the only correct choice, and the solution does not need a process, it can be obtained through guessing, reasonable reasoning and estimation. This can often reduce the amount of calculation and naturally strengthen the level of thinking. Estimation saves a lot of derivation and complicated calculation, and saves time, so it is fast. Widely used, it is an important operation method for people to find, study and solve problems.

In fact, the most important thing is substitution. Some options, you just need to bring them in, which is actually very simple. Of course, part of it is luck. Hehe, there are many methods, which vary from person to person. Me too. We are going to take the college entrance examination this year. Come on! Wish you success! ! !
