It affects the answer because parentheses signifies or implies that yoy are doing the operation inside of their that step comes first because if you forget about that step and move on it will affect your answer and you will get it wrong write this down
Hi there again! Anyways the answer is simple. The parenthesis r there for a reason. It is to show that that part is the one that u have to do first. So if the problem was (5-3)-1+2 u would have to do the parenthesis part first or u would get the wrong answer. I hope this helped u!
