You can put this solution on YOUR website!
With combinations, you don't care about the order
of the things being counted.
Suppose +n+=+10+
+10C10+ is the combination of 10 things taken
10 at a time. There is only 1 of these, since you're
looking at all 10 of the things.The same is true no matter what n is
