    answer is dos
    You work multiplication and division from left to right. Same with addition and subtraction.

    So.....


    9+3= 12
    then
    48/2 = 24
    then
    24*12= 288

The commutative and associative laws of addition and multiplication allow terms to be added in any order and factors to be multiplied in any order, but mixed operations must obey the standard order of operations.

    It is helpful to treat division as multiplication by the reciprocal (multiplicative inverse) and subtraction as addition of the opposite (additive inverse). Thus 3/4 = 3 ÷ 4 = 3 • ¼; in other words the quotient of 3 and 4 equals the product of 3 and ¼.

    So basically if you make the "÷2" part equivalent to "*0.5" then you have all multiplication left and you get 288. Boom.
    Indeed.

    I's right though. I think people just forget the PEMDAS means that it group M and D as well as A and S.

    Again see my proof with using the inverse of the divisor to make it all multiplication. It's 288.

    If the answer is 288 then every single math teacher I've had from grade school to graduate school is an idiot.

    Mult. and Division are in the same league so you go left to right. Same with addition and subtraction

    The rule is actually:

    P-E-MD-AS


    NOT


    P-E-M-D-A-S


    MD are together, AS are together. Multiplication or Division. Addition or Subtraction. Going left to right.

    For the really in tune, the "2" crowd uses the rule of distribution, which says 2(9+3) is rewritten as 2(9) + 2(3). So 18 + 6 = 24.

    Making the final answer 2 NOT because "lolololol left to right division/multiplication fail lololololol" but because the rule of distribution re-writes the equation as above.

    The more I listened to both sides, from serious math people arguing as well, I came to the conclusion of 288.

    The reason being that the equation is poorly written, and no one would ever actually write an equation that way. It's a troll trick.


    Edit: Bolded my responses, as I've seen this thread play out a number of times, and have seen every argument.
