input: Write a function to perform several simple math operations on two given integers and print the results of addition, subtraction, multiplication, division, and modulo. The function should accept two integers as inputs and print the results of each operation.
  
  assert perform_operations(10, 5)
  assert perform_operations(20, 2)
  assert perform_operations(7, 3)
  assert perform_operations(18, 6)
  assert perform_operations(15, 4)
output: def perform_operations(a, b):
      print(a + b)
      print(a - b)
      print(a * b)
      print(a / b)
      print(a % b)
