    Nobody has argued exponents should go before brackets.

    I’m saying distribution being mandatory is an invented rule from your part.

    No wonder you can’t produce such a simple request. I thought you had calculators that work “correctly”?

    • Nobody has argued exponents should go before brackets

      You did! 😂 You said 2(3+5)²=2(8)²=2(64), which is doing the Exponent when there are still unsolved Brackets 😂

      I’m saying distribution being mandatory is an invented rule from your part

      You still haven’t explained how it’s in 19th Century textbooks if I “made it up”! 😂

      If you don’t remember Roman Numerals either, that’s 1898

      No wonder you can’t produce such a simple request.

      says person who still hasn’t produced a single textbook that supports anything that they say, and it’s such a simple request 😂

        Unsolved brackets

        Solving brackets does not include forced distribution. Juxtaposition means multiplication, and as such, 2(3+5 is the same as 2*(3+5, so once the brackets result in 8, they’re solved.

        Distribution needs to happen if you want to remove the brackets while there are still multiple terms inside, but it’s still a part of the multiplication. You can’t do it if there is an exponent, which has higher priority.

        Your whole argument hangs on the misinterpretation of textbooks. This is what it feels like to argue against Bible fanatics lmao.

        Tell you what, provide me a solver that says 2(3+5 is 256 and you’ve won, it’s so easy no?

          Solving brackets does not include forced distribution

          Yes it does! 😂

          Juxtaposition means multiplication,

          No, it doesn’t. A Product is the result of Multiplication. If a=2 and b=3, axb=ab, 2x3=6, axb=2x3, ab=6. 3(x-y) is 1 term, 3x-3y is 2 terms…

          as such, 2(3+5)² is the same as 2*(3+5)²

          No it isn’t. 2(3+5)² is 1 term, 2x(3+5)² is 2 terms

          so once the brackets result in 8

          They don’t - you still have an undistributed coefficient, 2(8)

          they’re solved

          Not until you’ve Distributed and Simplified they aren’t

          Distribution needs to happen if you want to remove the brackets

          if you want to remove the brackets, YES, that’s what the Brackets step is for, duh! 😂 The textbook above says to Distribute first, then Simplify.

          while there are still multiple terms inside

          As in 2(8)=(2x8) and 2(3+5)=(6+10) is multiple Terms inside 😂

          it’s still a part of the multiplication

          Nope! The Brackets step, duh 😂 You cannot progress until all Brackets have been removed

          which has higher priority.

          It doesn’t have a higher priority than Brackets! 🤣

          Your whole argument hangs on the misinterpretation of textbooks

          says person who can’t cite any textbooks that agree with them, so their whole argument hangs on all Maths textbooks are wrong but can’t say why, 😂 wrongly calls Products “Multiplication”, and claimed that I invented a rule that is in an 1898 textbook! 🤣 And has also failed to come up with any alterative “interpretations” of “must” and “Brackets” that don’t mean, you know, must and brackets 😂

          This is what it feels like to argue against Bible fanatics

          says the Bible fanatic, who in this case can’t even show me what it says in The Bible (Maths textbooks) that agrees with them 😂

          provide me a solver that says 2(3+5)² is 256 and you’ve won, it’s so easy no?

          provide me a Maths textbook that says 8/2(1+3)=16 and you’ve won, it’s so easy no? 🤣

          And in the meantime, here’s one saying it’s 1, because x(x-1) is a single Term

            • This is a college textbook, and that explains how to solve it

              It’s a college refresher course on high school Maths. They also forgot to cover The Distributive Law, which is not unusual given college Professors don’t actually teach high school Maths.

              Another example

              From the same refresher course 🙄

              Alternatively, here is another example

              Which also doesn’t cover The Distributive Law, which isn’t surprising given that chapter isn’t even about order of operations! 😂

              In case you can’t find the correct part

              Still not about a(b+c). You lot are investing so much effort into such an obvious False Equivalence argument it’s hilarious! 😂

                Don’t move the goalposts. I’ve posted textbooks showing that “solving brackets” only applies to the inside, and distribution is part of multiplication and optional.

                You’ve said yourself your magic rule is taught in highschool, so a refresher course in college would never ignore it.

                Now instead of giving weak excuses, provide your part of the proof. And I’m not talking about multiplication, I want to see anywhere where a distribution is given precedence over an exponent.

                • Don’t move the goalposts

                  I didn’t. You’re the one who has been desperately trying to make a False Equivalence argument between a(b+c) and a(bc)² 🙄

                  I’ve posted textbooks showing that “solving brackets” only applies to the inside,

                  No you haven’t. A college refresher isn’t a Maths textbook, and I already pointed out to you that they don’t mention The Distributive Law at all, unlike, you know, high school Maths textbooks 🙄

                  distribution is part of multiplication

                  And the high school Maths textbooks I posted prove you are wrong about that 🙄

                  and optional

                  And the high school Maths textbooks I posted prove you are wrong about that too, 🙄 unless you think “optional” is a valid interpretation of what “must” means 😂

                  You’ve said yourself your magic rule is taught in highschool,

                  Yep

                  so a refresher course in college would never ignore it

                  And yet you proved that they did in fact forget about it 🙄

                  Now instead of giving weak excuses

                  they say to person who has been backed up by every textbook they posted so far 😂

                  provide your part of the proof.

                  Just scroll back dude - they’re all still there, like here for example.

                  And I’m not talking about multiplication

                  Well that’ll be a nice change then 😂

                  I want to see anywhere where a distribution is given precedence over an exponent

                  Because you are hell bent on making a False Equivalence argument between a(b+c) and a(bc)². I don’t care dude. there is no exponent in the meme. I’ll take that as an admission that you are wrong about a(b+c) then.

                    Who are you talking to?

                    All I said was: If 5(4)2 is 5*16, like this college math textbook shows, then 2(8)2 is 2*64.

                    Every published example will agree this is how it works. None, at any level of education, will agree with your bullshit.
