  5.  *	BEHAVING AS MATH TUTOR
  6.  * _____________________________________________________________________________
  7.  * 
  8.  *	This program acts as a math tutor for a student. It displays two random
  9.  *	numbers to be added, pauses while the student works on the problem, then
  10.  *	displays the problem again along with the correct solution when the student
  11.  *	is ready.
  12.  * 
  13.  *	Computation is based on the formula:
  14.  *	Sum = Number1 + Number 2
  15.  * _____________________________________________________________________________
  16.  * 
  17.  *	INPUT
  18.  *	  number1, number2: Randomly generated numbers to add
  19.  * 
  20.  *	OUTPUT
  21.  *	  sum			  : Sum of number1 and number2
