input: Write a python function to add two numbers, subtract the second number from the first, and then sum the results with an additional 1. 
  assert add_two_numbers(5, 3) == 9
  assert add_two_numbers(10, 5) == 16
  assert add_two_numbers(7, 2) == 11
output: def add_two_numbers(a, b):
      sum_result = a + b
      subtract_result = a - b
      final_result = sum_result + subtract_result + 1
      return final_result
