    *jaw drops* *is appalled on the amount of people who got this problem wrong* Wowzers, it's not 288, it's 2 according to PENDAS mathematical order.

    not really... Espresso explained it on the first page...

    to make it simpler its the same as 48 ÷ 2 x 12, whereby anyone with any Maths qualification can work out the answer from there... 288.

    i believe in PEMDAS method(popular in States&China), rather than the STANDARD order OF operations one.
    There is nothin rite or wrong, academically 2 is the correct answer.Dont believe? Ask ur math teacher.PROBABELY THEY CANT TELL...
    IF U R A STRICTLY STANDARD ORD OF OPERATIONS USER, the answer should be(48/2)*(12)=288.

    I use BE/DM/AS.
    I use what operation comes first in the equation for DM.

    It actually depends on what the situation is. You need base the equation on a real life problem.

    can't believe this is still going...
    funny reading back, how so many don't have "logic"

    There is no incorrect answer for these two cases.

    pemdas / bedmas / bidmas / or whatever u wanna call it... it's still order of operations
    regardless how u see it, division/multiplication take same level of precedence, just as addition/subtraction take same level

    there is only ever one answer...
    it's just a matter of logic that's misinterpreted or misunderstood

    brackets/parentheses always take precedence regardless what logic u use
    exponents/logs are next
    multiplication/division
    addition/subtraction

    and it's not like u have to do multiplication before division or vice versa... that's what's misunderstood, along with how the brackets work

    Basically, yep. Solved it with like BEDMAS, or the way I was taught.

    It's really up to what you do first.

    48 ÷ 2 x 12.

    Division first, u get 288
    Multiplication first, u get 2

    Basically that's what I did.

    But this BEDMAS and PEMDAS thing is yeah...

    If it's put into a fraction, then it'll be much more comprehensive. Or an extra bracket.

    exactly... but its not atm... so how ever u go...


    pemdas = parentheses, exponents, multiplication, division, addition, subtraction
    bedmas = brackets, exponents, division, multiplication, addition, subtraction

    parentheses and brackets are the same thing, so it doesn't matter if u wanna call it a P or a B
    multiplication and division both have the same precedence level in either method, so it's same thing as using MD or DM

    the names are just used so people have a "name" to remember it by
    so regardless which "method" u really pick, you should still get the same result

    the only real issues that the methods don't cover are negatives
    -3^2 (im sure there are those who understand that... essentially negative 3 squared... depending how that's interpreted, its either the negative of 3 squared, or negative 3 squared)

    -3^2 = -9
    (-3)^2 = 9

    Again. The brackets determines the outcome.
