The answer is one.

Brackets always first, even if there is only one number in them.

Get a scientific calculator and type in 6÷2(1+2).

You'll get 1 as the answer.

6÷2(1+2)
=6÷2(3)
6÷6
=1
 
I know it doesn't matter :)

But surely as there are brackets and a division sign then you would have this:

6/(division)2(multiplication)(1+(addition)2)(brackets)

Therefore you complete the content of the brackets first: 1+2 = 3
Then you multiply the coefficient of the bracket by the bracket itself (something that my school, sixth form and university teachers have always told us to do, as it is part of the brackets): 2*3 = 6
Then you complete the division: 6/6=1

I understand that the equation is written very ambiguously, but I can't see any other solution :)

And yes Castiel you are right, I'm just waiting for Mr. Postman to deliver me some prezzies, and this is more fun than playing cod :)



Our resident maths genius (my LSE educated wife) says pretty much the same, as there is nothing separating the brackets from the 2, thus the only answer you can arrive at is 1.

To equal 9, it would read 6/2*(1+2) or something like that.

But equally she says it is a nonsense formula designed specifically to confuse.

You really have to, to avoid trolling on such a massive level as the creator of the poll for this on Facebook.

Must have realised there were this many err... (I don't know how to put it without sounding like an ass) people in the world. I think this guy can take the prize for being the most epic troll I have seen :)

Just asked my coursemate Chris (and even though he is from essex, he is quite smart :D) and he said much the same. But yeah, postman is knocking, PREZZIE TIME! :D

Edit: Agree with your edit :)
 
I run an IT area for an investment bank. Even though I've only been there for about 6 months I jumped at the chance to get involved in their graduate recruitment programme. I really do value the importance of offering people a career and guiding them through their early years to fulfill their potential.

But... over several weeks we interviewed numerous people and nearly everyone who was offered a job at the end of the process was someone from another EU country. I was part of the team deciding on who went through, and the standard from other EU couhtries was not only higher but the commitment shown by the candidates was much higher.

The UK candidates seemed to waltz in, assuming they were king of the hill because they had a degree, and really showed no hunger or desire in life.

It was quite an eye opener I'm afraid.

I think that there's one thing you're missing though, the European people you're interviewing are naturally going to be showing a hunger or desire for life as they're the ones who have up'd sticks and moved to the UK so will have greater confidence levels in general so you're going to be looking at a more specific band of people. The ones you're interviewing from the UK will naturally be the full broad spectrum and will include the ones who really cannot give much of a monkeys.

If you flipped sides and went abroad you'd find exactly the same thing. I too realise it as I work in zone 3 London and most of the international people who I interview come across, generally, much better than the local population but that is because of who these internationals are and their background.



Anyway back to the subject, the people who are saying it's 9 you fools cannot see the ambiguity in the question. It is like how you're taught through life, if you've not done advanced maths before then you'll say 9. You can make an analogy to the sun. At one stage in your life you believed that the sun rose and dipped daily but you didn't know that it was because the Earth was spinning. If that's where your education stopped then without understanding the spin of the Earth you'd be entrenched in the camp of 'clearly the Earth spinning is nonsense'. Weak analogy I know but if some of you people who just went 'its 9 I did GCSE maths you idiots' bothered to read some of the posts you would see a clear distinction in what answers are coming from what educational backgrounds.

It is still ambiguous and is designed to separate those who are capable of saying it's both and those who are blind and saying it's one of them only.

+1

I came up with 1, but it's a really badly written question. Brackets first, then the way it reads seems to imply doing the multiplication next which gets you to 6/6=1.

Edit: my maths background is a mediocre physics degree :D

Ummm... I know that 2(2+2)=8... But you said that the bracket 'function' was 2(2+2)=8
i.e. That this whole lot is first in the order of which part to do first.
So, following that logic, this would mean that 2(2+2) would be the same as 2x2+2 which is 6, which is clearly wrong. Anyone with an idea of how to do maths knows that it's 8, so clearly there is a fault in your idea that the 2 in front of the brackets is included in the bracket. This is where you are going wrong.

.... I still have no idea how you got 6 out of that. You're not processing any part of that equation before the other, but changing the function - making the coefficient a multiple instead. If you're processing the coefficient first, you multiply both terms within the brackets by the coefficient, which gives (4+4).

To be honest, I think Vonhelmet's post pretty much sums it up the best:

I'm enjoying the disparity in the arguments:

Camp 9: It's 9 you uneducated morons! Any fool with a D in GCSE maths knows this!

Camp 1: It could be either, but if a problem like this appeared in my degree level maths the answer would probably be 1.

Pretty much says it all, doesn't it?
 
6/((1+2)+(1+2))

or

or 6÷2(1+2)
6 / (2+4)
6 / 6
= 1

A* at GCSE would suggest i wasn't exactly talking out my arse btw 'Haircut'.

6
_____
2(1+2)

also gives 1 and it's framed the same way as the question in the op

ahhh no, I don't know whether someone else has said so but I read to this post and just no.

You can't assume that 2(1+2) is one term unless it is in brackets, maths is very much a black and white subject, if it is written on one line and no brackets are used then it has to just relate to BODMAS, so it has to be the 6/2 first then the x3 after because we are english and read left to right.

Wow, how can you do a physics degree and not know this... physics is based entirely on maths gah...

If you started let alone finished your degree then you would know that with maths you can not imply at all, you find results based on what you know, not what you think might be true...

BODMAS rules all!!

Finished my degree ten years ago thank you.

Without more brackets the question is ambiguous. I'm not the only one with a maths background who thinks the answer is probably 1. What we need is for the question to be written properly.

It doesn't, though. It's a mechanism designed to help children with their GCSE maths. Why do you think anyone doing or done with degree level maths or a subject that relies heavily on it, like physics, comes up with 1 with a note to say the answer is ambiguous?
