double-6 set of dominos?
Hint: There will be a double-0, a
double-1, double-2, and so on, to
double-6. As you solve the

Answer:
So, there will be:
0-0
0-1
0-2
0-3
0-4
0-5
0-6
That's 7 dominoes with a 0 on them. Since the 1-0 won't count because it's already been listed, how many dominoes have a 1 on them?
The 2-0 and 2-1 dominoes won't count a second time, so how many dominoes have a 2 on them?
