48÷2(9+3) = ????

What about taking the ÷2 as a *0.5? Would anyone disagree with that, and why? Both ways the answer is 288.

I brought up this exact same point and it has been ignored by all the 2 people. If the invented "juxtaposition" rule did take place then you could not substitute multiplying by 0.5 for dividing by 2, which is completely ridiculous.
I've had 3 years of college calculus. I understand why people want to distribute the 2 by habit. I doesn't make it right. When you see problems from algebra it's very clear what is in the denominator and what is in the numerator, which is why this doesn't come up. 2x/1x is rarely if ever written on one line like that. For example, this is what division looks like in algebra - 3. Division of Algebraic Expressions . Its very obvious what goes where.
My CPA, fiancee (an A+ advanced math student) and myself all came up with 2.
I can't believe this thread is still going. Who fucking cares, lol?

If 10x÷5x does equal 2 then the juxtaposition rule must exist
If you put that expression into the same site as the post above:
10x÷5x - Wolfram|Alpha
Voila! It equals 2
Now take the same equation and just add the corresponding multiplication signs (as most people want to do with the 2 and the brackets in the OPs equation).
10*x÷2*x and you get 2x^2
10*x÷5*x - Wolfram|Alpha
Now, as the two equations are exactly the same (if you don't believe in the juxtaposition rule) then how do they both get different answers?

Anyone ever hear of implied parentheses in division? It's 2. And I'm a math teacher. Also, no mathematician would ever use that bloody stupid division symbol. We always use the fraction bar. The answer is still 2.
At last we got a Math teacher to come and answer this question
However, I am not convinced that "÷" symbol implies parentheses (I'm not a Math expert). It should be true since it is coming from a Math Teacher. Can you please explain a bit on it.
Yes I agree that no mathematician would ever use that bloody stupid division symbol. I have never used it after my 3rd or 4th grade.
Thank You

It has nothing to do with the symbol at all, which is one of his points. Multiplication by juxtaposition, or implied multiplication by parenthesis, is done before division no matter the symbol used.
It's simply a matter of inadequate formatting - BODMAS was never intended to be used with in-line arithmetic statements. As a mathematician I make the assumption that everything after the fraction bar is underneath it; a non-mathematician may make a different assumption, I don't know. I don't see it as 48/2 x (9+3), but 48/(2(9+3)).
OMFG. YOU IZ SO SMART.
Thing is though, it's not written like that, is it?
If it was, we wouldn't be having this fucking debate.
It's all about context:
You're a pimp and have been asked to provide entertainment for a EWA party.
There are 48 super-affiliates from the network going.
You have 9 under-aged traffiked girls from Estonia and 3 Brazilian trannys.
To bolster the numbers, each prostitute says they will bring a friend.
You're trying to work out how many clients each prostitute will have to fuck.
You write down on a piece of toilet paper (whilst curling one out):
48/2(9+3)
Do you tell your small gaggle of ho's they will have to suck-off 288 affiliates, even though you know only 48 losers are going to the event? Don't be such a daft cunt. The answer is two shags each, no more, no less.

You are right, but 101 people disagree with you. Kind of like religious debates. You will never convince them.
