| Abstract |
The purpose of this paper is to use the combination of number and form to guide students to simplify the solving process and improve the solving efficiency of multiple choice questions. The main use of case analysis method, grasping the common points to simplify the solution process. The result of this paper is to get the "three steps" to simplify the process of solving, to help students solve the abstract function of college entrance examination efficiently.
