Using only the numbers 1 3 4 6 make 24. Each number can be used only once. Any of the 4 operators ( + - x / ) can be used any number of times.




Go.

That isn;t the entire question - you forgot

You can (and must) use each digit only once. Note that you may not "glue" digits together. (14 - 6) * 3 is not a solution. 1^3 * 4 * 6 is not a solution either (powers not allowed).

1 + 3 = 4
* 6 = 24
But you haven't used the 4 in the original numbers.

3 / 4 = 0.75
1 - 0.75 = 0.25
6 / 0.25 = 24
