美籍匈牙利数学家G.波利亚在《怎样解题》这本书中提到:当你解决了一道题目,你要思考三个问题:你能利用它吗?你能利用它的结果吗?你能利用它的方法吗?所以我们带着以上问题,来看看本章的一些例题,能不能得出一些新的结论、新的思考?例1苏科版《数学》九年级上册第100页问题2:学校广播站要招聘1名记者,小明、小亮和小丽报名参加了3项素质测试,成绩如下(单位:分)
The American Hungarian mathematician G. Polya mentioned in the book “How to Solve a Problem”: When you solve a problem, you have to think about three questions: Can you use it? Can you use its results? Can you use its method? So we take the above questions, take a look at some of the examples in this chapter, can you come up with some new conclusions, new thinking? Example 1 Suko version of “Mathematics” Grade 9 on the 100th book Page 2 Question 2: The school radio station needs to recruit a reporter. Xiao Ming, Xiao Liang, and Xiao Li have enrolled in 3 quality tests. The results are as follows (unit: points)
