A long long time ago, in a math class far, far away..

A long long time ago, in a math class far, far away. There was no way to take the square root of a negative number. Every time we squared a negative number. We got a positive. (-1) = 1 (-2) = 4 (-3) = 9. Is there a number, that when multiplied by itself. gives you a negative???.
