Not sure if you actually need help (Math that people learn probably around 8th grade?) or not but I will state the steps below.

if the parentesis would grab the "2" it would have been the first option.. it clearly means u divide 48/2 then multiply it with (9+3)

just how i see it

When I learned this in school it was PEDMAS. PEMDAS sounds silly.

Ok I guess you guys don't roam other forums, but this equation is being posted all over various sites, I do not actually need help with this, it is just that almost every forum it has been posted on 50% say 2 50% say 288.

Edit: I would love to see what you think the answer is poehalcho, and show us how you got it.

Edit 2: As you can see by the poll people are already splitting up between the 2 answers.

brah u trolling? its 288

its not 48/24, its 48/2*12

rule is 48/2 first, then 2*12. so its 24*12=288. multiplication and division are done in order of which goes in equation first, from left to right.

Edited your title so people will stop posting like idiots.

48÷2(9+3)

hookies go first so 9+3 = 12
then it's just 48 / 2 * 12.
just go from left to right -> 24 * 12 = 288.
double checked with calculator.

I must admit at the moment of the post I just rashly clicked 2 since usually when I see 2(x+y) they're in a separate part and get some kind of priority. nonetheless 15 seconds later in the bathroom I was like... wait a sec.

BIDMAS
brackets
indicies
division
multiplication
addition
subtraction

however + and - and also x and / are commutative, meaning order doesnt matter

48÷2(9+3) =

(9+3)(48)/2 =

= 288

look how ever you want to try put it, as you stated the brackets it will work as folling
48/2=24
(9+3)=12
therefore you could write it in simple terms as 24*(12) or just 24*12=288

not always but most of the time you should work left to right, sometimes not the case

Epic thread on this in the misc over at bb.com, is that where you got the idea?Went on for almost 90 pages and had 3000 votes.. Ended up about 50/50 between 2 and 288.

PEMDAS

Parenthesis
Exponents
Multiplication / Division
Addition / Subtraction

You work left to right on MD and AS.

48/2(9+3)
48/2(12)
24(12)
288

An engineer, math professor, etc would never write the problem down like this in the first place.

I see we have a fellow miscer :)

I agree with 288, when I first saw it I was quick and rationed 2 as the answer, but I double checked and 288 seems correct.

I am not much of a lurker , I wonder what is all this about , it is a rather simple equation , Took it at school 3 years ago and a bit this year so i remember it well , here you go :

48/2(9+3)
48/2*12
24*12
288

i went to school so the first thing that came to mind was the answer isnt 2 thus without working it out i can deduce the answer must have been 288

2(9+3) = (2*9 + 2*3)

48/2(9+3)
48/(2*9 + 2*3)
48/24
2

48/2X
X = 9+3 = 12
2X = 24

This is how I view it.

no you work out whats in the brackets before you add the multiplication,

so its not (2*9 + 2*3) its 2(9+3), but you need to work out the first part of the equation before you multiply

You can't distribute that 2, it's attached to the division operator.

What happend to the distributive property classifing that as one whole term?
