Question

一到一百怎样算简便

Answer 1

一到一百简便计算可以使用“高斯求和”法

（1+100）×100÷2=5050

---

操作方法

从1加到100等于5050，算法为(1+100)+(2+99)+(3+98)+…+(50+51)=50×101=5050。

从1加到100的简便算法为对数列进行重新排列，组成50个101的式子（1+100，2+99，3+98…），就可以得到1+2+…+100=50×101=5050，也被称为高斯求和。

Answer 2

一加到一百的简便运算。
这一类题目是有公式的：（首项+末项)x项数÷2.
即：（1+100）x100÷2
=101x50
=5050

Answer 3

等差数列，这个知识是高中的
（1+100）x100÷2
=101x50
=5050
