2. Asks the user for a 2-digit number
3. Asks the user for a 3-digit number

• Make sure that the input is correct

4. Perform a simple calculation for:
   1. Multiply
   2. Add
   3. Subtract (must be able to tell the user if this wont work)
5. Display the correct choices and calculations at the bottom of the page displaying the user name
