My Sample Lesson 2

Square roots

Introduction:
A square root of a number is a number that you can square or multiply by itself. For example, square root of 4 is 2 because 2 x 2=4. But numbers like 13 and 15 don’t have square roots because there are not the answers of two same numbers. So, remember a square of a number is that number times itself.
√100 = 10 because 10 x 10 =100
