    It’s organized so that more powerful operations get precedence, which seems natural.

    Set aside intentionally confusing expressions. The basic idea of the Order of Operations holds water even without ever formally learning the rules.

    If an addition result comes first and gets exponentiated, the changes from the addition are exaggerated. It makes addition more powerful than it should be. The big stuff should happen first, then the more granular operations. Of course, there are specific cases where we need to reorder, or add clarity, which is why human decisions about groupings are at the top.

      Yeah, but that’s why I like to buff my base attack before I invest in multipliers and armor penetration!

    • The big stuff should happen first, then the more granular operations

      The “big stuff” is stuff that is defined in terms of something else. i.e. exponents are shorthand for repeated multiplication… and multiplication is shorthand for repeated addition, hence they have to be done in that order or you get wrong answers.

        “Wrong answers” only according to our current order of operations, math still works if you, for example, make additions come first (as long as you’re consistent about it).

        OFC it is a convention and to change it you would have to change all expressions ever written all at the same time, to avoid confusion between competing standards. I’m not arguing that it should be changed, only that there is no ‘high truth’ behind it.

          No, according to arithmetic.

          No, it doesn’t - order of operations proof. The only way it could work with addition first is if we swapped the definitions of addition and multiplication around… but then we still have the same order of operations, all we’ve done is swapped around what we call addition and multiplication!

          there is no ‘high truth’ behind it.

          There is when it comes to order of operations.
