You have to total 15. You must use 5, 4, 3, and 1 each once and must use each number. You can add, subtract, divide, or multiply to get to 15.
Example (yet incorrect) 5x3 = 15...15+4=19 19-1 = 18.
Obviously wrong because you need 15 but anybody know this. I think there is two solutions! THanks

Also I remember it uses division like a fraction. Ex. = 1/4 or something? I forget and this is killing me!!!!

I think you need the 2.
Then it'd be 4 + 1 = 5 + 5 = 10 + 3 = 13 + 2 = 15
The numbers 1, 2, 3, 4 and 5 all add up to 15.
Another way of doing it without a 2 might be:
(4 + 1 = 5) x 3 = 15
You've used all the numbers only once, with the 5 being an answer as well as part of the equation. That's not the same way that you have it worked out though. If you want it as a progressive equation, try working it out in a matrix (change options and numbers until you find all the possibilities and answers) That'd take a while though and I can't be bothered doing it!
