Arithmetic Questioner is a simple program to help
improve the user's mental arithmetic. When provided
with the largest numbers to add, subtract, multiply
and divide, the program randomly generates maths
questions. The program accepts whole numbers and
then tells the user if they are correct or not. If
the user is incorrect the program tells the user 
the right answer.
