2. u fatty
it doesnt work like that
for eff sake lol
ive been watching this thread since it started...

bloody hell... cant u c the brackets???

brackets mean do it first!

ANSWR is 10 !

I have 2 maths degrees.

I graduated from oxford 3 years ago.
3. Even google said it was 288
4. Given that this question has started a huge debate, with good and bad arguments from both sides, perhaps we should regard 48÷2(9+3) as not well-formed and, therefore, unanswerable in its current form?

I think we're missing a set of brackets. You get two from 48÷(2(9+3)), and 288 from (48÷2)(9+3).

Which one you think 48÷2(9+3) implicitly implies is up to you. I, personally, don't think it implies either as I think it is ill-formed.

33 pages?

I'm think about it. I asked a Maths lecturer who does Topology and he said it is 2.
Did it take him 33 pages to solve it?

Yes, we get that you think it's 2; I can see why you think that. I can also see why others think it's 288.

However, if you think this argument is getting pointless (a point on which I agree with you), I think you need to put more stress on the ambiguity thing; by quoting qualification and then stating either 2 or 288 you are simply encouraging others to carry on making wild statements that it's "definitely" one or the other.

alright...i get it...
i have throughout the thread supported the ambiguity argument, but i am also allowed to have my personal opinion the matter and I am allowed to state that. Just like many others, I find it hard to let my argument slip when it's an opinion i feel strongly about, however i have fully stressed that by no means am I 100% correct and there is no other possible answer.

Female intuition LOL!!!!!!
Yeah, good for you...
9. I understand this is ambiguous.

HOWEVER, surely, due to its inherently ambiguous nature, we should simply work from left to right, as it's all we can do, giving 288.

To get "2" as the answer, you need to assume extra brackets, which we cannot do unless the person who posed the question clarified.

48= ?2(9+3)
Put your thinking cap on and tell me what you just assumed by writing this line.

I hope you didn't spend long on this.
11. When a number is next to a bracket you assume multiplication, right?
..And in the order of which operators you use first which is taught from school, multiplication comes first unless there are brackets.

So with the absence of any other brackets in this calculation I would assume that the answer ends up being 2.

No, brackets first, then multiplication and division equally, working from left to right.

Which gives 288.
13. i think its 288

Okay yeah brackets first, but the rest just makes my brain hurt trying to figure out which should come first!

There's nothing ambiguous about the question

If I asked you what is the answer to y=2^2x where x=2 what you you say the answer is? 8 or 16?

Theres nothing ambiguous about it because any mathematician worth their salt knows that unless you put brackets around the (2^2), then it's equal to 2^(2x)

2(9+3)?(2(9+3))

You can make assumptions that means but frankly, the assumptions are wrong.
18. 48/2(9+3) = = 288. Q.E.D.

48 / 2 x (9+3) = 48 / 2 x 12 = 24 x 12 = 288

Oh and I'm asian so I win
20. So, we get anywhere constructive in the last 11 hours (and 100 posts)?

Didn't think so.

(Honourable exception to Nuodai).
