    To square a number, just multiply it by itself ...

    Example: What is 3 squared?

    3 Squared = = 3 × 3 = 9

     

    "Squared" is often written as a little 2 like this:

    square root of 9 is 3
    This says "4 Squared equals 16"
    (the little 2 says the number appears twice in multiplying)

    If you square a number then you multiply that number by itself. For example, three squared = 3^2 = 3 x 3 = 9
