On any exam I'd write 2 cause of this:

Try to make it like this:

(I replace 48 with X , and put 2 to try if its correct)

x / 2(9+3) = 2
x / 2(12) = 2
x / 24 = 2
x = 2*24
x = 48  > Correct


Now, i replace 48 with X again , but this time i put right side 288 ( = 288 ) i get :

x / 2(9+3) = 288
x / 2(12) = 288
x / 24 = 288
x = 288*24
x = 6912 > Not correct (not 48)


END OF STORY

so why wouldnt you divide x (48) with 2 first ?

but Google  made this kind of calculation  48  ( 9 +3 )
                                                                 --------------- 
                                     48                                 2
while should  be   -------------------
                                 2 ( 9 +3 )

It seems like my previous explanation was not enough for u guys, ill try to make it easier for u guys to understand why answer is 2.

So lets think of the number 24; 24 = 18+6 right?

Now lets write "18+6" in parenthesis of 2 which leads us to 2(9+3)

Now if you have completed elementary school you should be able to understand that 2(9+3) is an entire statement and it CANNOT be broken up.

So lets get back to 48/2(9+3)

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

I hope everyone can uderstand now. In this case Left to right thing doesnt work.
that's not an explanation.
number 24 can be wrote down as a 48/2 which is also part of equatiation.


Also 48/2 can be written down as a 48x0.5

so there should be no talking about priorites in dividing and  multiplying.

Do you even understand? 2(9+3) is an entire statement which CANNOT BE BROKEN UP

Edit: Oh and also lets try your way, lets write 24 as 48/2

= 48/48/2
= 48.2/48
= 2
I hope this was simple enough for you.

NOT TRUE MAN. the 2 before (9+3) may very well be seperated , and in this cause it has to be cause its in division with 48.

lol you all get confused whike using /

48÷2(9+3)

48÷2 *(9+3)

48     ÷          2         *         12

but you all use

48/2(9+3) and fuck everything up....

Do you even read?, How old are you?, Can you understand simple maths?

2(9+3) can be written as (2*9+2*3); 2(9+3) is a math sentence an entire statement breaking it up is same as breaking normal sentences its like You want to write "I am going to play dota" but you write it down as "I going play dota"

I am 24 dude , and i know math for sure . But your view of this is wrong , 2(9+3)  is not an entire statement. if the problem would be written like that 48/ [2(9+3)] then 2(9+3) would be an entire statement

+1 to everything he says, i am tired to have debate around elementary school math problem

P.S. thing like a sentence and a statement don't exist in math, statement do but has nothing to do w/ this things.

/ is used as divide and if it's written like this 48/2*(9+3) = 288
On exam you would get above example and the answer would be 288 but in this case answer can also be 2
It can be broke but as i said above writing 2(9+3) can also be considered as [2*(9+3)] in which case the result would be 2
btw tyger 48/2(9+3) can't be wrote like this 48/(9*2+3*2) it can be written like (9*24+3*24)

Now if you have completed elementary school you should be able to understand that 2(9+3) is an entire statement and it CANNOT be broken up.

So lets get back to 48/2(9+3)

2(9+3) = 24
48/24 = 2
Why don't u first divide the 48 to 2 then multiply with that (9+3)=12? the paranthesis musn't make u give pesmission in the operations which is OUTSIDE the paranthesis, so 48/2(9+3)=48/2*12, this is the part you are wrong, its NOT 48/(2*12) so you CANT do that multiplication first, you must divide, then multiplicate. Lets make this even easier looking  for you.

Actually, that paranthesis does not mean anything in this calculation, just write 12 instead of (9+3) and see the fact.

courier power ure right,even u writed as a fraction  look here:

we have this fraction ok?48/2 and its multiplyed by 12  (9+3)
we reduce terms 12 with 2 and it remains 48*6=288

so i was wrong.also 12 can be written as 24/2
and if u make 48/2*24/2 will be same as 24*12 wich is 288.
so here is the demostration.
