      Same as PEMDAS, except: Parentheses -> Bracket Exponent -> Order Multiplication <-> Division

      BODMAS

        I learned it as “BEDMAS”

        Brackets

        Exponents

        (You can guess the rest)

        But when I learned BEDMAS, my teacher directed us to do implied multiplication before other multiplication/division. Which, as far as I’m aware, is mathematically correct according to the proper order of operations (instead of whatever acronym summary you learned).

        Before I get "umm. Acktually"d … I know that’s not the full picture of the order of operations as it should be in mathematics. But for the limited scope I learned of algebra from highschool, AFAIK, this is correct to the point that I have understanding of. I’m not a mathematician, and I work with computers all day long and they do the math for me when I need to do any of it. So higher understanding in my case is not helpful.

          Order is often used to describe exponents when talking about functions and other mathematical properties. In a lot of cases, it’s also equivalent to a degree. For example, a function y = x² - 9 is a second-order/degree polynomial.

          Alternatively, one could find a second-order rate of a reaction, which means the rate of reaction is proportional to the square of a solution’s concentration.

            You have the right idea, and you are right in some regards. Generally the order of magnitude is an order of 10. That is, 1350 could be represented as 1.350×10³, so the order of magnitude is the third order of 10, which is 10³ (i.e. some value x×1000).
