So I recently came to see this question popping, and answers were pretty mixed, so I wonder what you people think the correct answer is?

Calculate rule:
1.Bracket({}-->[]-->())-->Index(higher power to the lower one)-->Multiplication and Division-->Addition and Subtraction
2. Calculation in the same level -->Left to Right
So...

PEMDAS rule
48 ÷ 2 * (9+3)=
48 ÷ 2 * (12)=
48 ÷ 2 * 12=
48 ÷ 24=
2

or

Standard Order of Operations
48 ÷ 2 * (9+3)=
48 ÷ 2 * (12)=
48 ÷ 2 * 12=
24 * 12=
288

So, which is the real answer?

No, as add and subtract is actually in the same level,
Multiply and devide, too.
In the same level you calculate from left to right.

Bemdas ( Brackets, Exponents, Multiplication , Division, Addition then Subtraction )

48 ÷ 2 * (9+3)
48 ÷ 2 * (12)
48 ÷ 24 = 2

Nope, It is 288 for sure.

This is not a problem to me since I'm a Chinese user. This is how we calculate:
? ? ?? ??

?----Brackets=B
?----Indexs=I
??----Multiplication and Division=MD
??----Addition and Subtraction=AS

But let's see a simplier example,
48÷2x2

Would you say it's 12 or 48?

And a tip, a÷bxc=axc÷b

Multiplication and division is done from left to right

so it's

(48/2)*2

which is 48.
Easy.

Yeh, so why do they think multiplication need to do first?

Yes I always knew its 288. The problem is within the expression, since its an ambiguously written fraction, and since its written in bad form, it could lead to 2 different answers.
