Estimate, then narrow the range. For example, if you want to find the sqrt of 13, you know it's between 3 and 4. Try 3.5 - it's too low, so now try halfway between 3.5 and 4, 3.75 - it's too high. Now try a number between 3.5 and 3.75, say 3.6. It's just a bit low, so try 3.61, which is a bit high. Continue until your result is as close to 13 as you want.

It's better to get a scientific calculator if you need to do math like this.
