1．从个位起向左每隔两位为一节，若带有小数从小数点起向右每隔两位一节，用“，”号将各节分开；
2．求不大于左边第一节数的完全平方数，为“商”；
3．从左边第一节数里减去求得的商，在它们的差的右边写上第二节数作为第一个余数；
4．把商乘以20，试除第一个余数，所得的最大整数作试商(如果这个最大整数大于或等于10，就用9或8作试商)；
5．用商乘以20加上试商再乘以试商。

如果所得的积小于或等于余数，就把这个试商写在商后面，作为新商；如果所得的积大于余数，就把试商逐次减小再试，直到积小于或等于余数为止；
6．用同样的方法，继续求。

这种办法ms更适用于人+计算器，单用计算机做很繁琐

可以手工开的！
可以手动开平方！
手开平方,就是一种笔算出一个数的平方根,例25的平方根是5
以523.456为例加以说明
(1)以小数点为界,向左右两边分节,每两位为一节,右边数位不够时,用0补足
-------------------------
)5`23.45`60`00
(2)从左边第一节开始试根,想一个平方≤5的整数,就是第一节的根,把这个根写在第一节的上面,并把它的平方写在第一节下面,用第一节减去这个平方.很显然,第一节的根是2
2
-------------------------
) 5`23`.45`60`00
4
------------
1
(3)将第二节23移下来,与前面的余数一起试根,将第一节的根2乘以20,写在123的左边,想一个数a,使a*(40+a)≤123,并用123减去a*(40+a).可见第二节的根是2
2 2。
