 It is your task to enhance the program you wrote last week (**mtf0**) that will use loops and other programming concepts learned this far to automate the display of entire mathematical operation tables (addition, subtraction, multiplication, division, or remainder; as indicated by the user). This information is potentially of value to some of your letter division efforts in the pctX projects. It is your task to enhance the program you wrote last week (**mtf0**) that will use loops and other programming concepts learned this far to automate the display of entire mathematical operation tables (addition, subtraction, multiplication, division, or remainder; as indicated by the user).
