    Dpemas would be a fully valid mathematical order of operations. As would only left to right. Or right to left. Or only parenthesis.

    The ambiguity remains due to the ambiguity of division operators in single line phrasing and implied multiplication, not because of the shape of the operator lol

      Sure, if everyone on the world would switch over and accept that as the offical order of operations, it would be valid. But that’s not the case.

      So either learn the order everyone else uses … or be wrong.

      • That’s not what mathematically valid requires.

        You in fact likely have interacted with non pemdas or dot before line orders of ops before. Many calculators in fact follow left to right. Many programming language follow their own unique OoO.

        I don’t think you understand what wrong means.

          Yes, due to input limitations. That’s why you should know the proper OoO so you can enter them in the calculator in the correct order.

          Many programming language follow their own unique OoO.

          Yeah, they are literally different languages …

          I don’t think you understand what wrong means.

          You sure are giving me detailed demonstration.

          Let’s give me another example. If everyone switched the world “dog” and “shoe” and used them with inverted meaning … everything would be fine. The world would go on without issue. It’s fun though experiment.

          But as soon as you go around point at people’s shoes and calling them “dog” or seriously campaigning for the words to offically swap meaning … well then you’re just being retarded.

          • Not just due to input limitations.

            I don’t need to give a detailed demonstration, we both agree that OoO is arbitrary and have examples of alternative systems. You agree on these points, you just want to claim addressing pemdas as arbitrary and disagreeing with a design choice is a slur.
