You can put this solution on YOUR website!
A=(4,6,8,9)
B=(2,4,6,8)
4%2B2=6
6%2B2=8
8%2B2=10
9%2B2=11
4%2B4=cross%288%29
6%2B4=cross%2810%29
8%2B4=12
9%2B4=13
4%2B6=cross%2810%29
6%2B6=cross%2812%29
8%2B6=14
9%2B6=15
4%2B8=cross%2812%29
6%2B8=cross%2814%29
8%2B8=16
9%2B8=17
C is the set of all unique sums of members of A and B.
C=(6,8,10,11,12,13,14,15,16,17)
C has 10 members in it.
