回顾我们处理数学问题的过程和经验会发现,我们常常是将待解决的陌生问题通过转化,归结为一个比较熟悉的问题来解决,因为这样就可以充分调动和运用我们已有的知识、经验和方法。也常将一个复杂的问题转化归结为一个或几个简单的问题来解决等等。这些方法的科学概括就是数学上解决问题的基本思想方法——化归
Reviewing our process and experience in dealing with math problems will find that we often solve unfamiliar problems by transforming them into a more familiar one, as we can fully mobilize and apply our existing knowledge and experience and method. Often a complex problem translates into one or a few simple problems to solve and so on. The scientific summarization of these methods is the basic method of thinking in solving problems mathematically
