    Which one is correct?

    Two Casio calculators; both with a different answer, which one is correct?



    Believe it or not, this has become a big debate at work

    9 is correct. You work from right to left when the parts have the same priority, supposedly.

    People are arguing PEMDAS; but they are saying the 2 (3) is multiplied first, because the 3 still has parenthesis. I agree with 9.

    People read it as

    __6__
    2(1+2)

    Well you do the parenthesis first.
    Then you do the multiplication/division, but you go from left to right.
    So you would divide the 6 by 2, then multiply that by 3 to get an answer of 9.

    Right because there's not actually an equation in the parenthesis after you do 1+2 and number(number) is multiplication, so then you'd do the division and then the multiplication.

    Calculators can be wrong! Who knew?

    PEMDAS says 1 but PEMDAS is just a simple mnemonic.

    Parentheses first - 2(1+2) = 2(3)
    No exponents.
    Multiplication and Division are both done in the same step prioritizing the leftmost operations... PEMDAS is a mnemonic, not a mathematical law.

    So it would be:
