    Anyone that doesn't think the equation is poorly formatted just doesn't want to be wrong. The equation is written as 48/2(9+3), which is the same as:

    48
    ________
    2(9+3)

    which equals 2...

    The answer is only 288 if you decide to interpret the equation as:

    48 (9+3)
    ___ x _____
    2 1

    which is not how it was originally written

    That's only part of it. The other part is if the 2 goes with the parenthetical information or if the parenthetical information only pertains to what's inside of the parentheses. Most people have been taught that a number directly outside of the parenthetical information is part of it, or at least it has more pull to it.

    This is correct.

    How do you follow the order of operations and not get 288?

    Is there a math teacher or mathematician here to confirm?

    That's because those people failed math. They probably never took anything beyond algebra because they couldn't pass the prereqs.

    Complete fail

    48/2(9+3)

    Step 1: Parentheses

    48/2(12)

    Step 2: Solve Equation Left to Right

    24(12)

    Step 3: Finish solving Equation

    288

    To you, the 2 is not apart of the parentheses. To those of us who got 2, it is.

    What are you talking about.

    Put this into excel

    =48/2*(9+3)

    and let me know what you get.

    2 is outside the parenthesis, dumbass.

    Is that what they are teaching in school now? That anyone who disagrees with you is a dumbass?

    No wonder the state of our education is so sorry.

    So you are saying 2/1 isn't the same as:

    2
    __
    1 ?????

    FAIL

    Same goes for the equation. If you look at it in fraction form, everything after the division sign would be considered the denominator. Simplify it from there and you get 2...

    ...and my post included how you get 288, but that's not how I view the equation.

    Bottom line is, if you got either 2 or 288 your math is correct, you just are reading the equation wrong.

    Do the equation on your computer calculator, you'll get 2.

    Math isn't debatable. It's right or wrong.

    Seriously, tell me about it. People still think the answer is 2.

    For the poor deluded people who feel PEMDAS requires doing multiplication before division, what do you think the solution to this problem is:
    2 - 3 + 1 = X

    Lol. Math is pretty black and white. You don't get commended for being wrong.

    There's only one way to view the equation, the correct way. You solve parentheses first, then you solve left to right. This is like 5th grade stuff. Freakin hilarious...

    This is incorrect and is probably where you got tripped up. You are interpreting the equation as if it were written like this: 48/(2(9+3))

    ...well once you start viewing it correctly you'll see it is 2.

    This made me laugh because it is so full of obvious fail (the bolded part), yet effort was put into it and the poster feels so sure about it.
