6##Create a basic operations calculator with the following features:
##1. Allow for the basic operations (add, subtract, multiply, divide) between TWO numbers
##2. Display the answer and allow them to perform another calculation
##3. Program the calculators using FUNCTIONS, PARAMETERS, and RETURN VALUES
##
##I will give you a preview of my program

#def addNumbers(x, y)
    #return x + y
