    Yep I have looked at all you’ve posted, I say you’re wrong because what you’ve posted says things that are true, but you’re reading them wrong. For example your last image clearly says a number next to a bracket means the content of the bracket must be multiplied with said number. Nowhere there does anybody speak of distribution taking precedence over other operations. In fact, nowhere in all sources I can find does it say so. Wonder why all screenshots you post use convoluted wording and wonder why you pop up everywhere arguing the same thing and keep getting downvoted? At some point you need to understand that if one old-ass calculator and selective reading of cherry picked passages is all the proof you have, when all modern calculators and algebra solvers go against you, maybe it’s time to reconsider.

    Juxtaposition taking precedence over other multiplications I can understand and it’s an arguable point. Distribution being a mandatory step and taking precedence over even exponents is just silly and unfortunately wrong.

    Also another thing: you’re a math teacher as you’ve said, and consistently ask if I think “random programmers” know more about algebra than you. What I say to that is I’ve met plenty of teachers who are wrong about things in their own fields, for one. And also, people defining the rules of all those algebra solvers aren’t the programmers, as you’d know if you looked a bit into product development. It’s domain experts, who also define tests and receive feedback on the software’s performance and errors. I’m sure (lol) you’ve sent feedback to them, and they probably looked at it and decided you’re wrong. As well all have.

    • you’re reading them wrong

      says the person who is actually reading them wrong, who is unable to cite any example of me reading it wrong

      clearly says a number next to a bracket means the content of the bracket must be multiplied with said number

      the content of the bracket - you just quoted that yourself and still completely missed what that means 😂

      Nowhere there does anybody speak of distribution taking precedence over other operations

      BRACKETS has precedence over everything 😂 So here we have an example of you reading it wrong

      nowhere in all sources I can find does it say so

      And can you find any source which says Multiplication takes precedence over Brackets? No. Another example of you reading it wrong

      Wonder why all screenshots you post use convoluted wording

      They don’t use “convoluted wording”! 🤣

      “the contents OF THE BRACKETS should be multiplied”

      “everything IN THE BRACKET should be multiplied by that number”

      Yet another example of you reading it wrong 😂

      wonder why you pop up everywhere arguing the same thing and keep getting downvoted?

      The only person downvoting me is the person replying, whereas the others are getting downvoted by others as well 🙄

      At some point you need to understand that if one old-ass calculator

      My brand new calculator gives the same answer! 😂 They all do now, except for Texas Instruments - the only one stubbornly still doing it wrongly

      selective reading of cherry picked passages

      Sure, I’m “cherry picking” the sections of textbooks about Distribution. Do you want me to post something random about a different topic? 😂 BTW, noted that you haven’t come up with any textbooks that agree with you

      all the proof you have

      And it is indeed proof.

      when all modern calculators

      Agree with me (except for Texas Instruments)

      algebra solvers

      Written by programmers who have forgotten the rules of Maths, and as pointed out by many people in forums.

      maybe it’s time to reconsider

      And yet, here you are not reconsidering 🙄

      Juxtaposition taking precedence over other multiplications I can understand

      Because BRACKETS - ab=(axb) BY DEFINITION 😂

      it’s an arguable point

      And is also the exact same rule 🙄

      Distribution being a mandatory step

      There’s a reason it’s called The Distributive Law

      taking precedence over even exponents is just silly

      BRACKETS taking precedence over Exponents is “silly”?? 🤣🤣🤣

      and unfortunately wrong

      BRACKETS taking precedence over Exponents is “unfortunately wrong”?? 🤣🤣🤣

      What I say to that is I’ve met plenty of teachers who are wrong about things in their own fields,

      You think they’re wrong you mean, person who is saying Brackets before Exponents is “wrong” 🤣🤣🤣

      people defining the rules of all those algebra solvers aren’t the programmers,

      Yes they are! That’s why they give wrong answers 😂 I told one he was wrong and he went and fixed it, being the one who had programmed it that way 🙄

      as you’d know if you looked a bit into product development.

      I know they are because I have spoken directly to them 😂 Maybe try asking some yourself, before making completely wrong statements

      It’s domain experts

      No it isn’t, as proven by personal experience. You know who uses domain experts? calculator manufacturers. 😂 They have considerably more riding on it being right or not.

      who also define tests and receive feedback on the software’s performance and errors

      You know there’s a whole bunch of programmers who don’t bother even defining tests to begin with, right??

      I’m sure (lol) you’ve sent feedback to them

      Yep!

      they probably looked at it and decided you’re wrong

      Except for the ones who did change it. The ones who claimed I was wrong, quoted Google - who have also been told they’re wrong by many people -and not Maths textbooks 🙄

      As well all have.

      says person who did nothing of the sort, and lied about such things as "all modern calculators " being against me (they aren’t, if you had actually tried some), Exponents having precedence over Brackets, etc.
