I suppose you 47% read from right to left as well

Nah, that would make the answer -3.66!

Its almost as if some are unconciously over-complicating it...

or maybe that's just my comfort reasoning as my maths is not as strong as it should be. I got a B in Math GCSE 11 years ago, but the more specific stuff I have long forgotten.

Know enough to get my by (just).

Aye I got a C , but 11 year ago, is a long time, I did GCSE maths 18 years ago, and the majority of the things I studied for on papers 1&2?(top papers back then) I've never used in real life, so you forget how to do them. If you don't use that sort of mathematics regularly it fades into obscurity with time......or blondeness, or age

the other alternative is BIDMAS

B rackets
I ndices
D ivision
M ultiplication
A ddition
S ubtraction

The answer is definitely 7. Unless you have different laws of maths to everyone else.

And in case you're interested, I did A-level Maths and I am doing a degree in Engineering at the moment.

Yeah and I work for a company that does Maths tutoring software for 5 to 13 year olds.

Think I'd better make myself an account up and get busy re-learning.

i love reading this thread. makes me laugh. Everyones arguing over a question which has an incorrect answer. i am doing a physics degree at the moment, (and should be studying, not on this forum) from my experience, exams and tests can get the wrong answers and leave out information in a question, so it can not be answered correctly. For instance in the maths challenge when I was at school there were 4 answers for a question none of which were correct.
another example would be a missing piece of information for a calculation in a moch test where the weight of an object was not inserted into the question, so the question could not be answered correctly with out it. Hence probably a mistake done by who ever had written it.

The same situation goes for this question, the bracket might be in the wrong place or a set of brackets missing. Therefore a mistake in the paper. Being as we probably study or have jobs we get lazy and dont check things properly, which has probably happened. for example i can do maths/physics etc, but i can not write a report to save my life as i am really bad at english and sometimes decide to skip out words and use the wrong weather, for wether.

my point exactly!

also the question was addressed to mathematicians. Which is someone who is educated in the field of maths and not just those who are able to read a book left to right.

being a physict i dont have a leg to stand on as some of the maths i do has many assumptions that allow me ignore some rules of maths, (assuming it would make sense in the laws of physics).

and just a comment about the engineer that said the answer was 5. LOL. LOL. and LOL again. (physics and engineers dont agree on many things, but cant exist with out one another). although to the engineers defence if someone has asked the question and said "(7-3)+6÷2=* i probably would have said five working it out as i go along. But if they had used their brain and written it down obviously you get 7.

now i better get on with some studying where i can do equations like:

N + 1 = N when N>>1

and you can all say i have no brain, and dont blow up the world with a black hole. (LOL at the dailymail and people's ignorance)
