It means 20 x 20 or 202 which equals 400.
It means to multiply the number by 2 or to add it to itself. So if the original number is 10, then double that number would be 20.
Well, a square number is the answer to a number multiplied by itself. So, what you'd have to do is multiply 20*20, and the answer is 400.
it means you sqaure the number (multiply it by itself)
Multiply the no. by itself. Ex 5 squared is 25.
When you multiply a number by itself, you square the number. The square of 3 is 9.
Squaring a number means to multiply it by itself, in this case, 20 squared (written 202) = 20 x 20.
