Pig is here. I didn’t know about it when I was at school. This time I saw it online and took note of it.
First, divide each digit from the decimal point into a section
For example: calculate √10
3. 1 6 2 2 7--- -----
-----------------------------
√10 '00'00'00'00'--------
3| 9 3 1st position 3
-------
6 1|100 2*3*10 1 =61 2nd position 1
| 61
-------
626 | 3900 2*31*10 6 =626 3rd position 6
| 3756
--------
6322|14400 2* 316*10 2 =6322 No. 4 2
|12644
---------
63242|175600
|126484
-----------
632447|4911600
|4427129
-- -------
××××××00 (continues in this cycle)
So, √10=3.16227-------
Another example is the root number 7
= 2. 6 4 5?
---------------------
2 | 7
4
--------------
4 6 |300
276
------- -------------
52 4 | 2400
2096
---------- ------------------
528 5 | 30400
26425
------ --------------------------
5290? | 3 9 75 00

Generally speaking, you can only memorize some common numerical memory methods. For example, 19*19=361, then find the square root of 361, which is 19.
But often the value is not that round, so you have to use a calculator. In fact, manual work can also be counted. For example, to calculate the square root of 20, first know that 4*4=16 and 5*5=25, then the square root of 20 must be 4 points. Then calculate what 4.5*4.5 equals, compare it with 20, and then determine the next digit. This is very troublesome, but it is the only way. The calculator also calculates based on this principle, but it calculates very quickly.
