Add a factorial method.  Everybody understands what it means before 
they are out of high school and it comes up all the time in statistics 
and combinatorics.  Ruby has a factorial method and heck even basic 
calculators have a factorial key.

print n.factorial()

Maybe raise ValueError if n is negative.
