What do you get when you multiply positive 3 by itself ?

(You get 9.)

What do you get when you multiply negative 3 by itself ?

(You get 9 again.)

The square root of a number is something which, when you

multiply it by itself, gives you the number.

When we multiplied positive 3 by itself, we got 9.

So positive 3 is a square root of 9.

When we multiplied negative 3 by itself, we got 9 again.

So negative 3 is also a square root of 9.

Every positive number has two square roots. They're both the

same digits, but one is positive and the other one is negative.
