2. In view of the three difficulties that may occur when students solve the series of application problems of equations, they should be consciously solved in the teaching process, especially when students are uncertain about the equation relationship, so that students can find out the equation relationship and express it as an equation through tables, charts and other forms. For example, in the process of analysis, 1, students can clearly and intuitively understand the difficulties in solving equation series through tables.

3. Through the comparison of charts, students can be more intuitive and have a deeper understanding. At the same time, it reduces the difficulty and weight of theoretical teaching and improves the efficiency of classroom teaching (teaching means).

4. In the arrangement of exercises after class, students should imitate the thinking method of examples and deepen their ability to solve practical problems. This is mainly because students are just beginners and imitate more. After getting used to it, they can do exercises different from the examples, which can improve their ability to use knowledge, and at the same time, it can also help students to solve more than one problem, find out the similarities, differences or best methods, and broaden their thinking.
