It should be in the right format. I, for one, would have asked the teacher where the brackets were. I may not have been bright in maths, but i always made it a point to clarify doubts as and when it arises.
Seriously, i believe that brackets are an integral part of your equation. If not, out of a 100 people, 10 (like you) might get the answer. The other 90, (like me and others) might not get it.
It is not fair to give math like this and think it is obvious to the whole 100. It isnt. With proper instructions (like the use of brackets) anyone can solve it. I am not with generalising people about their math abilities just because a question was not posed in a way suitable to them. It may be just me, but i count myself among the ignorant majority (Just like those people who shocked you in the first place).
