    Insert the correct mathematical signs ( + ) ( - ) ( x ) ( :- ) to make
    the following calculations work:

    7 8 20 32 = 44
    9 3 42 12 = 94.5
    8 2 12 9 = 37
    6 7 15 13 = 44
    5 32 6 20 = 18.75


    I couldn't do it.
    Finding the solution can't be just trial and error.
    Who wants to have a go ?

    7 * 8 + 20 - 32 = 44
    9 * 3 * 42 / 12 = 94.5
    8 * 2 + 12 + 9 = 37
    6 * 7 + 15 - 13 = 44
    5 / 32 * 6 * 20 = 18.75

    Do I win a prize?...
