Well, it’s been quite a few years, but in my education if you showed me 8/2(2+2) I would understand it as algebra, and as SgtHooper explains, the 8 being the numerator and the 2(2+2) being the denominator. If it were a math problem, it would be confusing to write it like this: 8÷2 X 2+2 and expect the answer to be 1.
Anything within the parentheses gets done first so 2+2 = 4.
The 2 connected to the parentheses is an operation on the contents within the parentheses. So 2×4 = 8.
Last, the division is the numerator 8 divided by the denominator 8.
So the answer is 1
