    Depending on how you solve it, your answer is either 288 or 2.

    Nothing is missing in the equation - no math symbol is missing between 2 and (9+3), so solve it as is.


    Now, cast your vote! :)

    How do you figure 288.
    The division automatically means anything to the right is The divisor.
    So
    48 divided by 2(9+3)
    48 divided by 2 x 12
    48 divided by 24
    Answer 2

    However if I was determining my salary 288 for sure

    After reading people's thoughts about it, without a calculator/computer doing the calculation your answer with be based off of which method you use to follow the order of operations.

    I did parenthesis, then multiplication or division from left to right. That's how I was taught it.

    I'm pretty sure doing PEMDAS left to right is the proper way to do it

    48/2(9+3)
    48/2(12)
    24(12)
    288

    Exactly.

    To avoid the 'implied' multiplication, it should be shown as below.

    The answer is then obviously "2".

    All depends on whether the (9+3) is on the top or bottom. As the OP typed it, it's on the top.

    48/2(9+3) = 24 * 12 = 288

    48/[2(9+3)] would've been = 2

    The answer is 288.

    Back to 7th grade Math: Order of operations= PEMDAS
    Parentheses first 9+3=12
    Then division 48/2=24 because 24X2 is 48. Multiplication and division go together.
    Then multiplication because they are next to each other. 24(12)=288

    Mac knows, that in the absence of a sign, the (9+3) is to-the-power-of. :p

    Well, you’re wrong. You’d need two more parentheses to SEE it that way.

    Well if that is acting as a fraction bar which acts like a grouping symbol (parentheses). So if then 9+3 = 12 12*2 = 24. 48/24 = 2. However, if that was a normal division symbol. then 9+3 = 12. 48/2 = 24 24*12 = 288. So is it a fraction bar or a division symbol yo.

    Yes, if you assume the (9+3) is a power.

    No, if you assume there is a fantom multiplier between the 2 and the (9+3).

    It's a loaded question, due to incomplete specifications, yet again.

    Takes me back to my User days. Kill them all!!! :mad:
