How to calculate square root?

To calculate the square root, you need to find the number which when multiplied by itself, gives the original number.

For example, if you want to find the square root of 250, you could estimate it to be between 15 and 16, since the square of 15 is 225 and the square of 16 is 256. Then refine your estimate by dividing the number by your guess and averaging it with your guess.
