• It’s true you resolve what’s inside the parentheses first, giving you. 8÷2(4) or 8÷2x4.

    Not “inside parenthesis” (Primary School, when there’s no coefficient), “solve parentheses” (High School, The Distributive Law). Also 8÷2(4)=8÷(2x4) - prematurely removing brackets is how a lot of people end up with the wrong answer (you can’t remove brackets unless there is only 1 term left inside).
