Stanford (or "standford") is not an Ivy League school. If you had gone to a halfway decent school, you'd know that.i highly doubt that. did you go to standford too? :roll:

The format used to program a computer to solve equations is not the same as writing out the equation in a format to be solved by hand.
BTW, if the 12 was supposed to be in the numerator, the equation would have been written:
48(9+3)÷2 or 48(9+3)/2
The fact that the equation was written:
48÷2(9+3) which is the same as 48/2(9+3) means that the (9+3) or (12) is in the denominator.
Numbers or variables to the left of the / are in the numerator and numbers or variables to the right of the / are in the denominator. Why? Because using the forward slash / symbol is how people type out the divide by line using a keyboard because they can't easily type out a horizontal line and put numbers and variables above the line for the numerator and numbers and variables below the line for the denominator. Thus, the / sign is used for convenience, with the numerator to the left of the / and the denominator to the right of the /.

This should help people pick the right answer.
What, you don't appreciate a free math lesson?Your sig says it all. Please stop humiliating yourself, seriously
What, you don't appreciate a free math lesson?
If the (9+3) is supposed to be in the numerator, please explain why the equation wasn't written as:
48(9+3)÷2
Putting the (9+3) to the right of the ÷ sign means it's in the denominator. Didn't you learn that in 2nd grade?
Yes, that's exactly it!Good to see some people stop and think rather than blindly following rules they learned in school.

The standard order of operations, or precedence, is expressed in the following chart.
terms inside brackets
exponents and roots
multiplication and division
addition and subtraction
In other English speaking countries, Brackets may be called Parentheses, or symbols of inclusion and Exponentiation may be called either Indices, Powers or Orders, and since multiplication and division are of equal precedence, M and D are often interchanged, leading to such acronyms as BIMDAS, BODMAS, BOMDAS, BERDMAS, PERDMAS, PEMDAS, and BPODMAS.

Is that a conclusion?

I am asking you, instead...
Yeah, that's the kind of person I'd never want as a co-worker, someone who is stubborn and can't admit a mistake.My TI-89 gives 288.
Matlab, Maple, TI-89, Wolfram Alpha, desk calculators, Mathematica, Google, mathematics PhD candidates, and certified licensed engineers all agree: the answer is 288.

The equation was written as such to make a point. It's not like the equation has malicious intent. The point is PEMDAS is apparently completely misunderstood...What, you don't appreciate a free math lesson?

Clearly, the teachers of America have failed here, since I so stupidly follow the ORDER of OPERATIONS, God forbid. I don't know how I ever got through my third calculus class in college without it.
Cool your jets, there's arguments to be made for each way of doing the math.
But what's in the numerator and what's in the denominator DOES MATTER!!!!!WOW, and you really think that way?!
Does not matter how equation is written!
Tell us if:
5-3+2 = 5+2-3 = 4
same is with 48/2*12 = 48*12/2 = 288
The ORDER of multiplication/division DOES NOT matter!!!
For those (sadly) educated in the USA:
"PEMDAS" = "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction"
B-A-S-I-C-S!!!
If you went to Harvard, wouldn't you know that Yale is also in the Ivy League? :roll:WHY???
Why would ANYONE need to know what Ivy League schools are???
Do they teach that in "a halfway decent school"???
Your arguments are...surprising...
I would stay away from here and stop wasting 30k posts on some forum and get to some BASIC education.
One day attitude like this may cost you a lot...
The rules of mathematics do not say that the (9+3) must be in the numerator. That was YOUR assumption.Here's the bottom line:
The rules of mathematics demand that the answer is 288.
What about it? What's to the right of the first / and to the left of the second / is in the denominator, and what's to the right of the second / is in the numerator.What about: 8+12/3(9+3)/15((12+3)*16)?
Everything to the right of the first / is in the denominator?
But what's in the numerator and what's in the denominator DOES MATTER!!!!!
The original equation of 48÷2(9+3) does not have a * arithmetic operative to make it clearer that the (9+3) is a separate calculation and not part of the denominator. Therefore, given the lack of the * sign when using a computer keyboard to type out the equation, whatever is to the right of the ÷ sign or the / sign is part of the denominator. The / sign is the same as a horizontal division line!
A * sign makes it clearer that the (9+3) is a separate operation and not tied to the 2. But, yes, one can still make an argument that it's still in the denominator. But given the limitations of computer keyboards and the mathematical equation typing conventions that have resulted from those limitations, if you don't use the * sign to separate the two parts of the equation, it is the accepted convention that the (9+3) is in the denominator because it is to the right of the /, which is the same as being below the division horizontal line.Using your logic, what stops the (9+3) from being in the denominator even if there was a *?
Just repeating what you already said doesn't make it correct.The original equation of 48÷2(9+3) does not have a * arithmetic operative to make it clearer that the (9+3) is a separate calculation and not part of the denominator. Therefore, given the lack of the * sign when using a computer keyboard to type out the equation, whatever is to the right of the ÷ sign or the / sign is part of the denominator.

The only FAIL here is you, because you're so damn upset over an internet forum. I didn't go to college, so fail x 10.

What argument? By your definition, everything after / has to be in the denominator. That * does jack.

But you attended college, like James Blake, right?
I thought you played college tennis and also graduated?
I cannot believe what I am reading... Do teachers in USA/UK really teach that PEDMAS/PEMDAS acronym? Seriously? That's one of the most anti-pedagogical acronyms ever created, as this thread nicely shows, since it implies precedence between M and D, and between A and S.
And Breakpoint is a friggin legend, but I don't want to be near anything he has engineered, so please publish a list, for public safety.
I was just kidding. Of course I went to college...and graduated...with honors....and played tennis too. I was just being a pip.
uhh pemdas is taught that m/d and a/s are interchangeable and you do whichever comes first

Precedence between M and D is harmless as I showed before.
Oh, really? What's the result of 6 / 2 * 5 ?
6 / (2 * 5) = 0.6
(6 / 2) * 5 = 15
If you went to Harvard, wouldn't you know that Yale is also in the Ivy League? :roll:
The only thing you asked me was a rhetorical question on how someone as strikingly dumb as me could ever get through the logic games portion of the LSAT. Then you volunteered your (probably made up) score. No one's interested guy. I don't feel the need to get into a d--- measuring contest with you.
