    1. Open the file:

    2. Add the following to the file:

      def add(n1, n2):
          return n1+n2
      def sub(n1, n2):
          return n1-n2
      def multi(n1, n2):
          return n1*n2

    Run Tests and Call All Four Functions

    1. Add the following to the file:

      n1 = 10
      n2 = 11
      print(add(n1, n2))
      print(sub(n1, n2))
      print(multi(n1, n2))
      print(div(n1, n2))
      n2 = 0
      print(div(n1, n2))
    2. Save and exit the file by pressing Escape followed by :wq.

    3. Call all four functions:
