Mastering the steps of solving problems is the first step to solve application problems. If you want to master the skills and skills of solving application problems, you need to master the basic methods of solving application problems. Generally, it can be divided into synthesis method, analysis method, graphic method, demonstration method, elimination method, hypothesis method, reverse deduction method, enumeration method and so on. The introduction of these methods here is mainly to help students master how to think and open their own doors of wisdom when they encounter application problems. These methods are not isolated. In practical problem solving, two or three methods are often used at the same time, and many problems can be analyzed in one way or another. The problem is that after mastering various methods, you can use them flexibly with the help of the quantitative relationship in the topic, and you must not apply the problem-solving methods by rote. 1. comprehensive method

Starting from the known conditions, two known quantities are selected according to the quantitative relationship, and questions that can be answered are put forward. Then take the obtained quantity as a new known condition, match it with other known conditions, and then put forward questions that can be answered, so as to deduce it step by step until the required results are obtained. This is a comprehensive approach. In the process of using comprehensive method, the known conditions of application questions are decomposed into several simple application questions that can be answered in turn.
