-*  You can either use an iterative or recursive function to solve this challenge.      *
-*  I am going to use an interative function. I am going to start with a value of 1     *
-*  for my total and then keep multiplying it by the next number until I reach num.     *
+* The challenge passes a string but it expects us to do Math on it so it needs to      *
+*  be converted to numbers. I will use the base 10 parameter of the toString()         *
+*  function to convert each entry in the array to a Number. Then I am going to         *
+*  multiply each entry in the array to get a total. I will repeat this until my        *
+*  total is a single digit number. The number of times I multiplied is returned        *
+*  as the answer.                                                                      *
