1.  Write a subroutine to take a numeric value from 1 to 9 as an argument
	and return the English name (such as one, two, or nine).  If the value is
	out of range, return the original number as the name instead.  Test it with
	some input data; you'll probably have to write some sort of code to call the
	subroutine.  (Hint: The subroutine should not perform any I/O).
	
2. Taking the subroutine from the previous exercise, write a program to take
	two numbers and add them together, displaying the result as 
	Two plus two equals four.  (Don't forget to capitalize the initial word!).
	
3. Extend the subroutine to return negative nine through negative one and
	zero.  Try it in a program.
