  Internalized PEMDAS without knowing it’s literally the same thing as BODMAS is exactly the problem!

    what in the name of fuck is BODMAS

    • TheOakTree@lemm.ee ⁨2⁩ ⁨years⁩ ago

      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? how does that make sense? brackets alright ig

    I mean … yea. The exact problem is math is not taught correctly. Order of operations make total logical sense for what the operations are doing.

      The exact problem is math is not taught correctly

      Every single Maths textbook I’ve seen teaches it correctly. The issue is people not remembering what they were taught (and then programming a calculator without checking it first). Calculators

  So better do higher math in Python? I agree.

  • MotoAsh@lemmy.world ⁨2⁩ ⁨years⁩ ago

    Python isn’t the only programming language.

      But a quite common pl in science.

  Counterpoint: C function pointers (or just C in general)

  Also: sometimes, a mathematician just has to invent some concept or syntax to convey something unconventional. The specific use of subscript/superscript, whatever ‘phi’ is being used for, etc. on whatever paper you’re reading doesn’t have to correlate to how other work uses the same concepts. It’s bad form, but sometimes its needed, and if useful enough is added to the general canon of what we call “math”. Meanwhile, you can encapsulate and obfuscate things in software, sure, but you can always get down to the bedrock of what the language supports; there’s no inventing anything new.

    Yea, that’s it. Math syntax was created for humans, and programming syntax had to always remain deterministic. It’s not an insult to either, just interesting how ambiguities show up often when humans are involved.

      Math should be just as deterministic as programming, but it’s not in some situations

      Maths is 100% deterministic for order of operations. The issue is people not following all of the rules. Order of operations thread index

        Math is. The syntax is arbitrary in some edge cases.
