#  check if 'num' is divisble by either 3 or 5. If true, check if divisible by 3 - 
#  print 'fizz' or if false ''. Same with 5, but print 'buzz'.  Came up with the idea when fiddling around
#  and had "num%3 * num%5 == 0 ? 'fizz' + 'buzz' : num".  I believe it works just like concatenating a string
#  Essentially, I believe that is what is going on, this is merely concatenating strings whichis why the '+' 
#  works to connect the two conditions; i.e., really connecting two strings.
