    Hello, pickbrain!

    This one has too many possibilities . . .


    Find 33 by using {2, 3, 3, 3, 5, 6} and (+, -, , )

    . . . . (2 \times 3 \times 5) + \frac{3+6}{3}

    . . . . (3 \times 3 \times 5) - (2 \times 3 + 6)

    . . . . (3-2) \times 3 \times 6 + (3 \times 5)

    . . . . 6^2 - \left(5 - 3 + \frac{3}{3}\right)

    But Carol Vorderman still has better legs than Soroban

    (for non-UK residence: This is a reference to the TV show Countdown, on which Carol Vordermam was the lighting calculator eye-candy who solved these problems to show the contestants how it should have been done)

    I think this one is wrong, as theres only one 6 in the given set, 6^2=6*6,..so..

    Btw very true, too many ways, such as (6*5)+3,..unless uve got to use all numbers, which i dont think so

    Edit 3 : Soroban, ur using the 2 as a power, but it doesnt really suit the (+,-,*,/) does it ?
