    Still not reading it properly.

    that's why i'm asking,is that dot means "divided by two times"?

    coz last i know,it just simply means "times" or multiply...

    It's not a dot, it's a division sign. So its 48 divided by 2 multiplied by 12.

    BODMAS says division first so it's 24 multiplied by 12 which is 288
    So signature
    wow
    much awesome

    so that thing which is not a dot but somekinda small dark square means division?

    if that's the case then...

    48/12=4...

    or i'm wrong,that thing means half then multiply...

    that'll be the only clear idea that makes the answer is 288

    Your encoding isn't set to read the elementary division symbol. It reads as:

    Forty eights divided by two, open parenthesis nine plus three close parenthesis.

    Your bitterness, I will dispel

    The order of operations says:

    Parentheses - Exponents - Multiplication - Division - Addition - Subtraction

    With the priority going from left to right.

    By that logic, the problem should go like this:

    48÷2(9+3)

    48÷2(12) the parenthesis go first, naturally.

    48÷24 Next comes multiplication, between the 2 and the 12.

    2 Being that there is only one action left, the answer is two.



    The trouble with this particular problem is that multiplication and division (like addition and subtraction) are often given the same priority status. The answer you come up with depends on what version of the order of operations your algebra teacher taught you in high school.
