下午第三节课,初二(1)班“数学兴趣小组”的活动开始了,组长小明在黑板上写了这次活动的主题是“浮尾数及其求法”. 小芳心直口快,抢先发问: “什么是浮尾数?好怪的一个名字!”小明笑了笑说: “名字是有点儿怪,但顾名思义,就是一个自然数平方后又在结果的末尾浮现了.比如62=36,6又在结果的末尾 After the third class in the afternoon and the activity of the “Mathematics Interest Group” in class two (1) started, the team leader Xiao Ming wrote on the blackboard that the theme of the event was “Float number and its method”. Xiaofang straightforwardly asked the question first. : “What is the floating tail number? It’s a weird name!” Xiaoming smiled and said: “The name is a little weird, but as its name suggests, it is a natural number squared and then emerged at the end of the result.
