input: Write a function to perform several simple math operations on two given integers. The function should output the results of addition, subtraction, multiplication, division, and modulo operations. If either of the integers is zero, the function should return an error message indicating that division by zero is not allowed.
  
  assert simple_math_operations(10, 5) == "Addition: 15\nSubtraction: 5\nMultiplication: 50\nDivision: 2.0\nModulo: 0"
  assert simple_math_operations(15, 0) == "Division by zero is not allowed"
output: def simple_math_operations(a, b):
      if b == 0:
          return "Division by zero is not allowed"
      return f"Addition: {a + b}\nSubtraction: {a - b}\nMultiplication: {a * b}\nDivision: {a / b}\nModulo: {a % b}"
