How do you find the square root of something?

Use the squish method. We'll use the square root of 10 as an example.

First, pick out a perfect square that is closest number that is smaller than the selected number.

In this case, this will be the number three. 3*3=9, which is one smaller than 10.

Divide 10 by 3, which is 3.33.. (round if needed)

Average the two numbers, 3.33 and 3. In this case, it is 3.166.. (again, round if needed)

Repeat and divide it by the original number. 10/3.33 is equal to 3.1579.

Then, average again.  The average between 3.1579 and 3.1667 is equal to 10.0001. If you want to be more precise, keep on repeating the process with the numbers.
