在近年来的各种数学竞赛中,经常出现这样一类问题,即在一定的规则下进行某种“操作变换”,问是否(或要求证明)能达到一个预期的目标?这就是所谓的操作变换问题.由于操作变换问题形式多样,解法灵活,往往需要一定的技巧.本文举数例,以帮助同学们掌握这类问题常用的解题思路,方法? In various mathematical competitions in recent years, there has often been such a problem that certain “operational transformations” are performed under certain rules and asked if (or require proof) can achieve an expected goal. This is the so-called operation. Transformation problem. Due to the variety of operational transformation problems, the solution is flexible and often requires certain skills. This article gives a few examples to help students master the commonly used problem-solving ideas and methods of this type of problem?
