input: Write a function to perform several simple math operations on two integers. The function should accept two integers as inputs and output the results of the following operations: addition, subtraction, multiplication, division, and modulo. The results should be printed in the specified format.
  assert simple_math_operations(10, 5) outputs 'Addition: 15\nSubtraction: 5\nMultiplication: 50\nDivision: 2.0\nModulo: 0'
  assert simple_math_operations(20, 4) outputs 'Addition: 24\nSubtraction: 16\nMultiplication: 80\nDivision: 5.0\nModulo: 0'
  assert simple_math_operations(7, 3) outputs 'Addition: 10\nSubtraction: 4\nMultiplication: 21\nDivision: 2.3333333333333335\nModulo: 1'
  assert simple_math_operations(6, 0) outputs 'Error: Division by zero is not allowed.'
output: def simple_math_operations(a, b):
      if b == 0:
          print("Error: Division by zero is not allowed.")
      else:
          print(f"Addition: {a + b}")
          print(f"Subtraction: {a - b}")
          print(f"Multiplication: {a * b}")
          print(f"Division: {a / b}")
          print(f"Modulo: {a % b}")
