input: Write a function that performs basic mathematical operations given two integers. The function should accept two integers as inputs and output the results of addition, subtraction, multiplication, division, and modulo. If the input integers are 10 and 5, the function should print the corresponding results for each operation.
  assert math_operations(10, 5) == [15, 5, 50, 2.0, 0]
  assert math_operations(15, 3) == [18, 12, 45, 5.0, 0]
  assert math_operations(7, 2) == [9, 5, 14, 3.5, 1]
  assert math_operations(20, 0) == None # division by zero should raise an exception and return None
  assert math_operations(-5, 3) == [-2, -8, -15, -1.6666666666666667, -2]
output: def math_operations(a, b):
      try:
          return [a + b, a - b, a * b, a / b, a % b]
      except ZeroDivisionError:
          return None
