Is it possible to find the square root of an number without a calculator.
There are probably many methods........you can read about a couple of them here......http://mathforum.org/dr.math/faq/faq.sqrt.by.hand.html

i dont know i belive it would be very hard to do that though it would take a math wiz

Yes, one approach is to use a divide and average approach.
Example: $$\sqrt{3}$$
Guess an approximate answer, say 2.
This is already close to the value provided by a calculator and becomes even more accurate if you use more decimal places and repeat the divide and average a few more times. This method was known for thousands of years.
