// Task #1 Practice: Refactor code that is all ‘stuffed’ into main()
// Define and call at least 2 subroutines that would help the program to be more understandable and re-usable.
// They should be MEANINGFUL not just like public static void printTitle() { System.out.println("**Simple Calculator**"); }
// They should produce (almost) the same output and behavior* as the original, 'stuffed main()' version
// 	*There is ONE boo-boo in the calculations...find it and fix it.
