Make Task

In these tasks you have to use the skills learned in the previous exercises to create a new program based on the requirements below.

• Define four subroutines – add, subtract, multiply, divide that add multiply etc two numbers and return the result. Each should have two integer number arguments.
• The user is asked to input two numbers. These numbers will be passed as arguments into one of the subroutines.
• The user is asked to input 1 to add, 2 to subtract etc.
• If they input 1, call the ‘add’ subroutine, input 2 calls the ‘subtract’ subroutine etc
• Output the returned result as part of a sentence.

Make sure that you check for the following things:

• The subroutine name is identical everywhere it is used (capitals matter)
• The subroutine call is not indented inside the subroutine
• The subroutine is defined before it has been called
