>>

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

>>

PEMDAS: parentheses exponents multiply divide add subtract.

48÷2(9+3) = ?

Is the same thing as

48÷2x(9+3) = ?

Dumbasses thinking its 2

>>

>>582532615

no its not , parenthesis are pretty much just numbers that arent there yet

>>582532641

Also , multiplications and divisions are on the same level , you go from left to right

you numbnuts will argue about anything

>>582532615

No. Division and multiplication are given equal weight so you just go by the actual order.

Technically it's PE M/D A/S or BOM/DA/S

Parenthesis means everything inside the parenthesis..

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

also, fuck you

>>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.

It is, as it is written.

48/2(9+3) does not equal 48/(2(9+3))

This one equals 288 and the other equals 2.

I have even given you a guide to help you.

Use it.

>>

>>582542878

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.

>>

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

2

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

/rant

The confusion comes from either a troll, or the confusion from the question being poorly written.

The equation inside the parenthesis is evaluated, and then the parenthesis are removed from the equation.

The equation could be rewritten as (48/2)(9+3)

Three operations, division, multiplication and addition.

>>

>>582554848

I meant parentheses, and yes I think I know what you mean and I guess yeah. That is what I meant

>>

>>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).

>>

>>582555808

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.

>>

>>582531928

It equals the amount of times OP has had sex + 288

>>

>>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.

or do you give your friend his half of the cats first, and you will get all of your cats pregnant with three males and nine females each

Honestly, pemdas is fine if you understand that multiplication and division are basically the same (just opposites), so they must happen at the same time. The problem is that when you write pemdas, it's difficult to signify that d and m as well as a and s each happen simultaneously.

Here, this will help you all forget about this problem or the way it was set up:

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.

I got the Riemann Zeta function evaluated at pi.

Fair enough, I went to an interesting high school. Redistricting left the school about 50% impoverished urban black and 40% very wealthy suburban kids. There was no middle ground. My school was full of stupid bitches too haha, whether they were ghetto hoes or wealthy bimbos, it was all pretty much the same.

> R.I.P your investments, paychecks, 401k and anything else u need in life for math.

Nice. I work in finance and make more money in a year than you will likely see in your life time. The answer is simple, you just have to actually understand and use the convention. Multiplication and division are basically the same, so once you get there you solve from left to right.

>>

why would 9+3 be in parenthesis and 48/2 not??? ergo one can reasonably assume that the 2 is to be multiplied by the (9+3) without having been divided into the 48

Sounds like your might have been better I went to a school that was 95% hispanics 3% blacks 2% asian and there were only about 3 of us that were white.

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.

Can't do calculus without algebra

You may be a high financial kind of guy who makes more money than I ever will, but on this one I will trust the ring theorist mathematician.

>>

>>582571431

Oh wow. That crowd is so "diverse" that it isn't even close to diverse haha. Mines wasn't bad, but it wasn't close to the best in the district or state. Then again, my high school was in a southern state know for generally being bottom 10 in the US for education, but it had crept up to the high 30s when I graduated. I don't know, it's been a while so it might be different now.

My school was terrible also living in pheonix with a school of mostly hispanics was not great. Thing is that since most of the students were illegal they all wanted my dick for their green card. Best part of my school was all the free pussy that I got. Regardless everyone there was stupider than a sack of bricks.

>>582549671

bitch those cant even do -2^2 correctly

>>

>>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.

>>

>>582572953

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.

This.

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

>>582573308

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.
