Hello there am having a little problem on solving this :S, I have four numbers given when by collecting them I get the 68 (for example), then I need to add for example 3 to one of them, 3 to the other, *3 the other and \3 to the other... something like this .. the opponent should not be repeated twice (X13)+(X2*3)+(X33)+(X4\3) and give 68 ... Examples: (X1  3) + (X2 + 3) + (X3 : 3) + (X3 * 3) = (not 68) (X1 * 3) + (X2  3) + (X3 + 3) + (X3 : 3) = (not 68) (X1 + 3) + (X2 : 3) + (X3  3) + (X4 * 3) = 68 :) I'd really appreciate your help!!

a + d/c + b  d/c + c*(d/c) + d/(d/c) = a + b + c + d or (trivially) use 1 instead of d/c.
