In PowerShell I would like to accomplish the following things:

1. Ask for the user name
2. Ask the user for a 2-digit number
3. Ask the user for a 3-digit number
4. Then, 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
