48÷2(9+3) = ??

[Mr.Gaga]

lol a friend just asked me this and I was like wtf...

is it 2 or 288?!

 

[Arabian.]

2 you jackass. lrn2maths.

 

[Afeld]

288

learn the order of operations

 

[LoftyLawnChair]

pemdas

 

[Vino]

2

 

[BlakeLively]

288. going left to right, with order of operations (divide and multiply are interchangable)

 

[Dhane]

lolz.

 

[soulskier]

() first

 

[Vino]

exact.

 

[broto]

this

 

[.newman.]

its 288. parentheses come first, then you go left to right
so it becomes 48/2(12). then you go left to right so you get 24(12) which equals 288.
done. learn to maths.

 

[DirtyDiabetic]

its 288. try going to school sometimes

 

[dat_ski_dude]

fulltilts?

 

[skithesprings]

well, it depends. technically it is written in an incorrect manner.
although it is pretty clear that you mean the first option, it could be interpreted as

a: 48/(2(9+3)) = 2b: (48/2)(9+3) = 288

 

[Wheaty214]

Everyone who said 288 is fucking retarded, yes you do the numbers inside the parenthesis and since the 2 is next to the (12) it is pretty much part of it. So you do 48÷ last, so it ends up being 48÷24=2. NOT FUCKING 288.

 

[jibmastaaa]

72 i think....parenthesis first: 9 + 3=12. Then multiplication: 2 x 12=24. Then addition: 24+48=72

 

[carbon.pulse]

LOL at people saying 288.

 

[skithesprings]

lawl

 

[soulskier]

i agree with tou, but i'm much nicer about it

 

[.frenchy]

So many mixed answers in here.. haha, some people suck at math I guess.

PEMDAS ftw.

 

[Vino]

lol this thread is going dildos

 

[3-6-steeze]

this.

It is 2.

 

[skithesprings]

or he could learn how to write it properly so there isn't any confusion.

 

[Arabian.]

My computer says it's 288 or 2. I get different values based on different languages o.0
I thought 2(12) went first cuz distributive technically comes before division of integers?

 

[Boily]

 

[.frenchy]

Now that I look at it again I keep getting different answers. god dammit.

 

[General_Ripper]

its 2.................wow

 

[Afeld]

I won't lose on the internet

 

[hellyeaaaah]

This is what I would say, without the uncontrollable fit of rage

48

2(9+3) = 2

 

[BiggE]

fuck me the division sign in the thread title looks like a plus (+) sign

 

[hellyeaaaah]

haha pretty much.

 

[Blurst]

Its fucking 288

Order of operations

Brackets

Exponents

Division

Multipliction

Addition

Subtraction

 

[Afeld]

this. Hahahaha

 

[General_Ripper]

yup thats how you write it.

 

[guargum]

dude it's PEMDAS... as in parenthesis, not brackets. get your math lingo right bro.

 

[pinhead_larry]

P.arenthesis

E.xponents

M.ultiplication

D.ivision

A.ddition

S.ubtraction

Original Problem



48/2(9+3)

Parenthesis



48/2(12) OR 48 / 2 X 12

Exponents (None)

Multiplication/Division (LEFT TO RIGHT)

24 X 12

THEN

288

 

[RiddleMeThis]

hhahaha its 288, nice try though. Please Excuse My Dear Aunt Sally!

 

[Arabian.]

Unless you take PEMDAS literally (which you should've come to the same conclusion if you did follow it), and disregard distributive properties, yes, it's 288.

 

[rommo]

For bedmas doesn't it mean brackets first? so you would go 9+3 first not 48 divide 2?

[corona]

it's for sure 2, just written very poorly.

9+3 is obviously first, so 48÷2(12)

now, sub in x=12

so 48÷2(x)

what would you do in that case?

quite obviously that is equivalent to 48÷2x or 48/2x

now, make it equal to 288 and it's:

48/2x=288

48=288(2x)

sub back in

48=288(24)

obviously wrong.

so, letting it equal 2:

48/2x=2

48=2(2x)

48=4x

sub back in

48=48

therefore it is absolutely 2

 

[General_Ripper]

Hmmmm. pretty sure when you wright 2(9+3). It implys that you are to use a very important rule for math.........retards

 

[General_Ripper]

yes thank you.

 

[.rotaG]

i thought the divide sign was a plus sign from the faunt and i was brutally confused

 

[Blurst]

dude I have been taught differently

 

[Arabian.]

brackets = []braces = {}parenthesis = ()
You WILL need to learn the difference for programming, higher maths, and theory.

 

[Jonny7]

that's just not weel written

 

[Moosen]

Okay so we all know PEMDAS correct? Well now there is a secondary rule that is a part of this, the Multiplication and Division are on the same level as well as Addition and Subtraction. For example once you break down a problem if you have division and multiplication together you just work from left to right and vice versa, same for addition and subtraction. Therefore 288[/b]

 

[corona]

I'm posting this again, in bold. so you see it.



it's for sure 2, just written very poorly.

9+3 is obviously first, so 48÷2(12)

now, sub in x=12

so 48÷2(x)

what would you do in that case?

now, make it equal to 288 and it's:

48/2x=288

48=288(2x)

48=288(24)

obviously wrong.

so, letting it equal 2:

48/2x=2

48=2(2x)

48=4x

sub back in

48=48

therefore it is absolutely 2

 

[Moosen]

I see. That seems correct. +K and negate my statement

 

[Afeld]

Its all how you look at it.

9+3 is obviously first, so 48÷2(12)

sub in x=12

so 48÷2(x)

what would you do in that case?

quite obviously that is equivalent to 48÷2x or 48/2x

now, make it equal to 288 and it's:

48/2(x)=288

24(x)=288

sub back in

288=288

what can "x" be? 12, just as it was subbed for
