逆向思维是数学中一种重要的思维方法。它是在研究问题时,从反面观察事物,去做与习惯性的思维方向完全相反的探索,顺推不行时考虑逆推解决,探讨可能性发生困难时考虑探讨不可能性.由此寻求出解决问题的方法.
Reverse thinking is an important way of thinking in mathematics. It is to observe things from the opposite side when researching problems, and to do the opposite of the habitual direction of thinking. When we can’t push forward, we should consider reversing the problem and discuss the impossibility when discussing the possibility of difficulty. way of solving the problem.
