*  Something I LOVE doing in programming is screwing with the
*  assignment in any and all ways possible.  I didn't like
*  how it simply used two values and did the math.  So, to solve
*  this issue, I created a new function (DoTheMath) that did the 
*  math and printed the four functions automatically...from there, 
*  I have it use A as 10 and B as 20, since the assignment demands
*  it, then I give the user an opportunity to use his or her own
*  values if he or she wants, and then it just uses the function
*  again, except with those values.
