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

* Each cipher must be used exactly once.

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

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

* Brackets are allowed.

The Question: Give the two solutions to this problem.

Answer: The two solutions are: 6/(5/4-1) and 4/(1-5/6).
