We think that there are three different solutions:
3 = 2+1 7 = 4+3 8 = 8+0 13 = 7+6 14 = 9+5
3 = 0+3 7 = 5+2 8 = 7+1 13 = 4+9 14 = 6+8
3 = 1+2 7 = 7+0 8 = 5+3 13 = 9+4 14 = 6+8
We think that these are the only solutions because you can only pair 3 numbers (3,7,8) with the 0. When you have paired off one of these numbers, you then cannot move around the rest of the cards.
