Some square roots can easily be calculated by hand. For example the square root of 4 is 2 and of 9 is 3. However, most of them are irrational which means that cannot be put in the form p/q where p and q are integers and q is not zero. So how do we find real numbers by hand that are irrational?
The best we can do is to approximate them. There are many ways to do this.
