Answer: +1
Step-by-step explanation: When you have a set of parentheses in an order of operations problem, you must simplify what's inside that set of parentheses first before you do anything else.
So our first step here is to divide 45 by 9 which gives us 5.
So in our next step we have 3 (5) - 14.
Remember to do multiplication first so we have 3 x 5 which is 15.
Now we have 15 - 12 which simplifies to +1.
