How is it possible to have a positive or negative answer to the square root of a number?

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.
