在解题过程中,每当遇到需要解决的问题包含多种可能的情况,而导致无法再对问题一概而论的时候,迫使我们必须按所有情况分开来讨论,相应得出各种情况下的结论,这种解决问题的方法就是数学解题中的分类思想。分类讨论是数学解题中的重要方法之一,在初中的数学 In the process of solving problems, whenever we encounter problems that need to be solved, which include many possible situations that can no longer be generalized, we are obliged to discuss separately according to all circumstances and come to the conclusion of various situations , This method of solving the problem is the classification of mathematical problem solving ideas. Category discussion is one of the important methods in solving math problems, and math in junior high school
