    The obvious:
    ((6* (50-5))-9)+4 = 265

    I've yet to solve one fully :(

    Lads.... the operators allowed in this game are addition, subtraction, multiplication and division. so Capt midnights solution up there is invalid.

    Anyone circumventing this from now on will be disqualified (and their post deleted).


    [edit] Just saw that capt was dragging the game back for that, never mind[/edit]

    75 /6 = 12.5
    12.5 - 1 = 11.5
    50 - 3 = 47
    47 * 11.5 = 540.5

    a bit frustrating....

    What a cracking thread, I love this part of countdown!

    henbane, chop chop and post a question!

    Henbane, it isn't clear for people subscribing to a thread when you edit your challenge into an old post ...

    75 + ((7-1)*5) + 7 = 112

    ( ( 25 * 4 ) + 2 ) * ( 5 + 3 + 1 ) = 918 is closest i can get, but heres another anyway:

    75, 50, 10, 25, 7, 2 ----> 701 (solveable)
