    What is correct - -11.4 squared = - 129.96 or 129.96? :confused:

    Positive. It's the square root where you have to do the +/- stuff.

    I'm figuring deviation. So, the latter is correct? Merci!

    Yep.

    (+) x (+) = (+)
    (+) x (-) = (-)
    (-) x (+) = (-)
    (-) x (-) = (+)

    When you square a number, it's + regardless of whether it's + or -.

    On a side note

    81 is the only number whose sum of its integers equals its square root

    Well damn. Now a dozen USMB members are figuring square roots like crazy to see if you're right about that.
