    magic square

    HI
    I need some help.
    In a square 3 x 3 using the numbers 1 to 9 once only put the numbers so that:
    the numbers on the top row minus the numbers in the 2nd row = the numbers on the 3rd row.

    trying this for about 4 hrs and am always 1 number out..thanks in advance

    It might not even be possible (or do you know for sure that it is?)

    Yes, my brute-force computer program shows that this is not possible.

    Definitely no solution...
    Unless he means:
    459
    173
    286

    459 - 173 = 286

    BUT there's 336 solutions of that style!
