The question is, why do they use a bracket in the first place?...

I disagree. The point is not the bracket itself, but the implied multiplication by skipping the "x" (multiply sign).8 / 2 x (2+2) is NOT THE SAME as 8 / 2(2+2)... Bracket is involved in both, but the former is 16, while the latter 1 because of the implied multiplication.QED

2 X(2+2) is not 2(2+2)??2 X(2+2) = 82(2+2) = 8??(Audio)

You're missing the point and looking at only a part of the whole.In 8 / 2 x (2 + 2) .... the order of operation is bracket first, then left to right with division having a higher precedence than multiplication. Hence 8 / 2 followed by x 4. i.e. 16In 8 / 2 (2 + 2)... the order of operation is bracket first, followed by multiplication, only then left to right with the division. Hence 2 x (4) first, followed by 8 / 8. i.e. 1Once again, the ambiguity in this case is because BODMAS doesn't say anything about implied multiplication

If the answer was meant to be 16, then it should be (8/2)(2+2) which it isn't. The second bracket is missing.(Audio)

No it's not actually. Google "Implied Multiplication" (it has a higher precedence than division )

I never heard of implied multiplication before so I actually google. ...
