first, you take a number. for my example, I'll use 12. 12x12= 144. 144 would be the square number, and 12 would be the square root. clarification: if you multiply a number by itself, the product isn't the square root, the factor is. and if your really stupid, here's this: 12x12=144 F F P F means factor P means product. happy now?
