It's not counting as in (1, 2, 3, 4...), it's counting as counting a very large number of items http://www.regentsprep.org/Regents/math/ALGEBRA/APR1/Lcount.htm

Say you pick out 10 books, you would have 10 books for the first choice, 9 for the second, and 8 for third So you would have 10*9*8 = 720 choices possible
