    With the ciphers 1, 4, 5 and 6 you must make 24, using the following rules:

    a Each cipher must be used exactly once.

    b The allowed operations are: addition, substraction, multiplication and division.

    c Ciphers may not be concatenated (so, for example, it is not allowed to use 1 and 4 as 14).

    d Brackets are allowed.

    Give the TWO solutions to this problem.

    6/(5/4 - 1) = 6/1/4 = 24

    4/(1 - 5/6) = 4/1/6 = 24
