Firstly I wrote down the numbers in my book 3,8,7,13 and 14. Then coming off the cards I wrote all the sums that made each number sistimatically (in order).After I wrote 0,1,2,3,4,5,6,7,8 and 9 then connected the numbers that made each number.
altogether me and my friends found 3 solutions to this problem.

My answers:
3=1+2
8=0+8
7=3+4
13=6+7
14=9+5

3=1+2
8=5+3
7=0+7
13=9+4
14=8+6

3=0+3
8=7+1
7=2+5
13=9+4
14=8+6
