原理:一般通过特殊来表现,特殊之中蕴含着一般。方法:特值、特例、取样、极端。一、特值法将某个隐含的未知数量取一个特殊的值,让这个特殊的值参与计算,求出问题的答案问题一:有一堆苹果,平均分给幼儿园大小两个班的小朋友,每人可得6个;如果只分给大班,那么每人可得10个。如果只分给小班,那么每人可得几个?分析与解:假定这堆苹果共有30个(为便于计算,可以取6和10个最小公 Principle: Generally through the special performance, special contains the general. Method: special value, special case, sampling, extreme. First, the special value method will take an implicit unknown amount of a special value, so that this special value involved in the calculation, to find the answer to the question One: There are a bunch of apples, the average size of two classes of children to kindergarten children, Each person can get 6; if only assigned to large classes, then each person can get 10. If only to small classes, then how many per person? Analysis of reconciliation: Assuming that this pile of apples a total of 30 (for ease of calculation, you can take 6 and 10 min
