Like I stated before where is the division sign? There isn't one.

The division sign is replaced by the slash making it a fraction and it is placed EXACTLY where the division sign was.

48/ 2(9+3)= 2
Actually, as per your link, the answer to our problem with be 288.

Following the example from mathopolis



Let:
u+v=48
t=12 <-as per (9+3)


48 x 12 = 288
2

From the above simplified equation, the only way we could get 2 as an answer is to multiply 48/2 to the reciprocal of 12, which we all know should never be done in this case.

I felt it my duty to derail the thread. I voted 2, and everything after is too on topic!

Do what's in parentheses first. The answer is 2

48÷2(9+3)

48÷2(12)

48÷24

2



EDIT: Just realized there's like, 11 pages in this thread. My bad. :/

48÷2*(9+3) = 48÷2*(12) = 48÷24 = 2

The Standard Order of Operations should not be applied in this type of equation.
~ 48÷2*(9+3) = ???

In both the SOOO and PEMDAS rules, parenthesis are simplified first before proceeding.
Both rule simply the equation to 48÷2*(12) or 48÷2*12

SOOO vs Pemdas
~ SOOO will basically simplify it to 288.
~ PEMDAS will basically simplify to 2.


The resulting answer between both differs due to dissimilar order of mathematical processes.
~ Division is applied before multiplication in SOOO.
~ Multiplication is applied before division in PEMDAS


SOOO should not be applied in this type of equation since 12 is simplified from a parenthesis which involved addition.
The sum, 2 is proceeded using the PEMDAS rule since multiplication must be done first since the equation wuz simplified from a parenthesis. And since 48 wuz not derived from a parenthesis we proceed with multiplication before division.

Google simplifies 48÷2*(9+3) into (48÷2)*(9+3), perhaps since it follows the SOOO in any type of equation. The indication of parenthesis in 9+3 depicts that such must be multiplied to 2. The absence of parenthesis in 48÷2 tells that both is not to be simplified first and thus 2 must be multiplied to the sum of the parenthesis before division is to be proceeded.

Therefore, there is only 1 correct solution to the equation which is 2

Crap, I'm not even sure of what I'm saying... i'm still a kid....

I just cheated; I entered the equation into a graphing calculator, exactly like this:
Code:
48/2(9+3)
Calc spit out 288...
