How do you find the square root of a number without a calculator in an easy way to learn

Question

I'm a seventh grader with trouble in square roots

Answer 1

its not eezee tu lern.   Me dont thank me remember all the detaels av the old hand wae tu duit.

suggest itterate...if want sqrt(10), step 1=get, perhaps ges 1=3

3*3=9 & 9 < 10, so yuno yu need bigger number

take a stab with ges 2...4...4^2=16 is 2 big

step 3...tri (3+4)/2=7/2=3.5...3.5^2=12.25 (2 big)

4...want smaller number so tri (3+3.5/2)=6.5/2=3.25, 3.25^2=10.5625...yer gettin kloes

but stil 2 big, so tri (3+3.25)/2=6.25/2=3.125...3.125^2=9.765625...even kloeser, but small

go on til yu get tired
