PEMDAS

it's 2 (the answer)

It ends up being 48 OVER 2(12) or 48/2x12 where you would always do the multiplication on the bottom o the fraction before dividing that number into 48

you obviously dont, because once you do the equation in the parenthesisi, you go from left to right because multiplicaiton and division are equally weighed.. kill yourself this isnt even highschool algebra
>>
>>582532615
the equation within parenthesis is done FIRST, then the whole remain equation is done left to right (in this case)

P
Parentheses first
E
Exponents (ie Powers and Square Roots, etc.)
MD
Multiplication and Division (left-to-right)
AS
Addition and Subtraction (left-to-right)

So the answer IS 288

48/2*(9+3)=48/2*(12)=48/2*12 (brackets remove because there is no longer a equation within it)=24*12

>>582533923
This. It's 288 you fucking retards who are saying 2...
>>
>>582531928

48/2(9+3) is such a noisy calculation.
mathmatically we can re-arrange our equation
48/2(9+3) = 48/(2*9+2*3)
or to simplify
48/(18+6)
48/(24)
2
>>
Depnding on order of operations you use it's either
(48/2)(9+3)
or
48/[2(9+3)]
In the first case it's (24)(12)=288
In the second scenario it's 48/[2(12)]=48/24=2.

It depends on the actual application of the equation. Needs more parentheses either way.

The equation is too ambiguous to be answered
>>
There is no standard convention as to which of these two ways the expression should be interpreted, so, in fact, 48/2(9+3) is ambiguous. To render it unambiguous, one should write it either as (48/2)(9+3) or 48/(2(9+3)).

The order in PEMDAS doesn't matter. The precedence for Multiplication is the same as Subtraction and the precedence for Addition is the same as Subtraction. If you see both Multiplication and Division in one problem, you go from left to right, neither is higher in terms of precedence (the same goes for Addition and Subtraction).

Honestly, PEMDAS was the most retarded thing that the American math system has ever taught anyone.

PEMDAS doesn't mean
>Parenthesis, THEN exponents THEN multiply THEN divide THEN addition THEN subtraction.
It actually means
Parenthesis THEN exponents THEN multiply and/or divide THEN addition and/or subtraction.

2(9+3) is a sub-parenthetical operation, the 2 is distributed into the parentheses before performing the internal addition. so 48÷2(9+3) = 48÷{(2x9)+(2x3)} = 2

Now if I really wanted to throw you fuckers for a loop, i'd explain how 48÷2(9+3)=2 but 48÷2x(9+3)=288. but i'll let you figure that one out.

No. Nothing is implied in mathematics.

No, because if the author wanted that, they would have written it that way. But using the obelus splits it out, creating its own set of parenthesis

First you multiply the 9 and 3 individually by 2, then add them together. 9x2 = 18, 3x2 = 6, 18+6=24. 48 divided by 24 = 2. easy.

No... they are two different operations which yield the same answer. but when preceded by 48÷... they have different orders of operations.
>>
>>582531928

First you need to factor 48, it's much too high a number for this crowd.
4(12)/2(9+3)

Then let's substitute with some variables...
U=12
4(U)/2(9+3)

b=2(9+3)
4U/b

F=4
FU /b

Solved.

Niggas this is 4th grade math... you first add 3 and 9, getting 12. After that, you divide 48 by 2, getting 24. If a number is next to a number in parentheses, you multiply them together, getting 288.

You wrote the equation wrong
>>
There is only one correct answer, and it is 2.

This is because multiplication using brackets, for example 2(4) = 8, takes precedence over multiplication or division using signs like the division or multiplication sign.

Therefore you would do the bracket-multiplication first before doing other operations.

Hence
48 ÷ 2(12)
= 48 ÷ 24
= 2

To simply an earlier post:

48 ÷ 2(9+3). Make sure the 2 is distributed through the parentheses first. This is why the 2*(9+3) gets solved first before being divided into 48.

48 ÷ (18 + 6)

48 ÷ 24

no, no it does not
in PEDMAS, "parenthesis" means that you perform the operation within the parenthesis first, so in this case 9+3, but you multiply it until after 48/2 since you could write it as (48)/(2)*(9+3) and it has literally the same meaning

>>
>>582531928
It's 288, using pemdas you get 48/2*12. A better way to write this would be with fractions, but the way it is written (without parenthesis around the whole right half) we have to assume we have 48/2*12=48*12/2 (commutative property in multiplication). Therefore we get 24*12=288.

>>582554102
That's not right. If the question was 48/(2*(3+9)) you would be correct, but as it stands you need to divide 48 by 2, then multiple the result by 12. The answer's 288.
>>
Depending on whether one interprets the expression as (48/2)(9+3) or as 48/(2(9+3)) one gets 288 or 2. There is no standard convention as to which of these two ways the expression should be interpreted, so, in fact, 48/2(9+3) is ambiguous. To render it unambiguous, one should write it either as (48/2)(9+3) or 48/(2(9+3)). This applies, in general, to any expression of the form a/bc : one needs to insert parentheses to show whether one means (a/b)c or a/(bc).

Yes there is. You just go straight from left to right if there are no parenthesis to clarify. a/b*c=(a*c)/b. You can change the equation by adding parenthesis to get a/(b*c) but that of course would get you a different answer because it's a different equation.

>>582555813
That is incorrect. 24/2*12=/=24/(2*12). Without parenthesis you get that 24/2*12=24*12=288 because after PEMDAS you just go from left to right.

>>582557537
Multiplication and division (similar to addition and subtraction) are grouped together and done from left to right once you've worked out the parenthesis and exponents. Why would you not do them from left to right? Why would you insist on doing all of the multiplication before doing the division? You know that for any non-zero, x, y, an expression x/y can be rewritten as x*(1/y), right? If x/y=x*(1/y), and multiplication must come before division as you say, one could change the value of an equation by doing absolutely nothing besides changing the form it is written in. That's not how it works.

You don't necessarily do multiplication first, you just start with whatever is to the furthest left and work your way right.

>>582568954
Wrong. You'd think that someone working a faculty member at a school as respected as Berkeley would know better, but I guess not. The standard convention is that once you have worked through parenthesis and exponents you do multiplication/division from left to right. There is a convention. It doesn't matter whether you start with the multiplication or division because only one is actually valid. If you wanted to evaluate 3*(1+4) you would get 15. Of course, if you were to evaluate the 3*1 part then add 4 you would get 7, but that goes against convention, so of course 7 isn't right.

Not to mention when you type "48÷2(9+3)" in wolfram alpha you get 288 (https://www.wolframalpha.com/input/?i=48%C3%B72%289%2B3%29). A lot of other programs give the same answer.

He said PEMDAS isn't a standard convention. It is. Obviously he has to be a lot smarter than I am and knows math better, but he probably hasn't done algebra in years. Here's a lesser known secret: really high level mathematicians tend to be pretty shitty at low level mathematics. It's because they never use them. He's a ring theorist, he has probably spent years working on things like proving sets are rings over specified operations and developing and proving assertions dealing with rings, groups, and sets. When you get to college level math, you don't see algebra like outside of remedial classes. This is especially true when you get to the second half of your math classes in university. Generally you aren't even dealing with solving things like this, you're working on the underlying ideas. He's right that it's a shitty form for the question, but he's wrong that there is no standard convention for solving it.

>>582572434
Yeah, but you only use the very bare essentials of algebra. Then again, at high level you don't really do a lot of calculus as you're probably thinking of it. My point is that after your first year or two of undergrad, math is not computational any more. It turns very logic/proofs heavy. If you remember geometry from middle school, that is more similar to upper level math (but obviously much more difficult) in that you spend your time proving things instead of graphing and finding the derivative of a function. It isn't computational because there are programs that will graph and solve stuff for you.

>>582572448
I'm guessing you don't understand how mathematics changes as you progress. You know who is surprisingly bad at algebra? Upper level mathematicians. You'd think they'd be good at algebra, but because they never use it and are so far removed from middle/high school algebra, so they tend not to be. After the first year or two of university math is no longer computational. You have programs that solve equations for you, but you don't have programs to prove that [0,1] is a compact set for instance.

I was going to ask where you lived, I figured south California, Arizona, New Mexico, or Texas. It's good that you got pussy, though haha. At my school a lot of hot rich chicks were pretty slutty, so that was pretty cash.

There are two answers, both of which are accepted. There is a reason why such a problem would never be seen in a textbook or on a standardized test. There is an ambiguity problem with the notation.

I teach SAT prep, I have never run across this sort of problem for a reason.

48÷2(9+3)
48÷2(12)
Even though "12" is in parenthesis, it's considered multiplication. Order of operations now says to go left to right .
48÷2=24
24x12=288

Obviously you don't know shit. You're probably a second year undergrad that thinks they know wtf they're doing.

Grad student at NYU here. Best applied math program in the world. Some of our professors are pure math professors that work specifically in computation and trying to solve things in polynomial or log time.

Math is computations at a higher level, just not some pure math. Keyword here is some.

Algebraists are interested in the P=NP problem. Topologists are interested in how to efficiently unknot something. All of these translate into designing an efficient computer program, which requires, you guessed it, computations.
