Explanation: The letter p stands for a number. Think of it as a placeholder or a box to put the number inside. In this case, we place 14 inside this box. We divide p over 2, so we divide 14 over 2 to get p/2 = 14/2 = 7
Then we subtract off 5 to get (p/2) - 5 = (7) - 5 = 2 which is the result of the evaluation when p = 14.
