    I need some help

    Hey! Could someone help me with this one:
    The result of addition of two numbers is eighty.
    I need to define those two numbers the way that
    their product would be as big as possible.

    You could always try a few pairs of numbers out, e.g. 10 x 70, 20 x 60, ... and see where it goes. Not sure exactly how I'd *prove* the answer without calculus, mind you.
