    24 Game Marathon

    Hi everyone. This is a 24 game marathon.

    1)You may only add, subtract, multiply, and divide. NOTHING else, INcluding exponents, just like the original 24 game.

    2)When you answer a problem, you must remember to make a new one up. It doesn't take long to make one up, but make sure it works. If the person doesn't make one up, then someone else can make a
    new pr
    oblem


    3)You may only make problems with one or two didit numbers. Otherwise, it gets too confusing

    4)Try not to repeat problems; people will get bored with them.

    Here's the first one:

    5, 5, 5, 1

    Re: 24 Game Marathon

    Are we allowed to use only three numbers? For example, 5 \times 5 - 1 = 24.

    Edit: 5 \times (5 - \frac{1}{5}) = 24

    6 \times \left( \frac{8}{8} + \sqrt{9} \right) = 24

    Re: 24 Game Marathon

    Nope, just realized my answer is probably in violation of rule #1 ... so is my question (bummer).

    Edit:  \frac{ 8+8 }{ 6 } \times 9

    Re: 24 Game Marathon

    Or 9 \times 8 - 6 \times 8.

    (6,5,5,4) --> 6 \times 4 \times \frac{5}{5} = 24.

    Re: 24 Game Marathon

    Is this good? I've never played the original 24, so here's hoping for beginner's luck.
    \frac{2*5}{5}*14

    [1,2,3,4]

    Re: 24 Game Marathon

    5 \times (2 + \frac{14}{5})

    1,2,3,4's super easy.

    Huh? 6 * (1 - 3/4) = 6 * 1/4 = 1.5 : that's not 24.

    Oops. I meant  6 \div (1-\frac{3}{4})=24
