Well, isn't that a happy little question! When you calculate the factorial of a number, you multiply that number by all the positive integers less than it. The last digit of factorial 99 is 0, because there are lots of factors of 2 and 5 in the multiplication, creating zeros at the end. Just imagine all those zeros as little trees in a beautiful forest of numbers!
