In this problem, following order of operations, I would divide 2 by 2 before I add 36. This would leave me with an answer of 37.
But if I add parentheses around 36 + 2 then that changes the answer.
First I add 36 and 2 and get 38, then I divide by 2 to get 19. Different answer because of where I placed my parentheses.
In the following three problems add parentheses to the problem to change the answer.
