    Because BRACKETS - ab=(axb) BY DEFINITION

    “Parentheses must be introduced”!

    But you understand E=mc2 does not mean E=(mxc)2.

    This is you acknowledging that distribution and juxtaposition are only multiplication - and only precede other multiplication.

    In your chosen Introduction To Algebra, Chrystal 1817, on page 80 (page 100 of the PDF you used), under Exercises XII, question 24 reads (x+1)(x-1)+2(x+2)(x+3)=3(x+1)2. The answer on page 433 of the PDF reads -2. If 3(x+1)2 worked the way you pretend it does, that would mean 3=9.

      I already answered, and I have no idea what your point is.

      This is you acknowledging that distribution and juxtaposition are only multiplication

      Nope. It’s me acknowledging they are both BRACKETS 🙄

      E=mcc=(mxcxc) <== BRACKETS

      a(b+c)=(ab+ac) <== BRACKETS

      and only precede

      everything 😂

        Then why doesn’t the juxtaposition of mc precede the square?

        In your chosen book is the example you’re pestering moriquende for, and you can’t say shit about it.

        Another: Keys To Algebra 1-4’s answer booklet, page 19, upper right: “book 2, page 9” expands 6(ab)3 to 6(ab)(ab)(ab), and immediately after that, expands (6ab)3 to (6ab)(6ab)(6ab). The bullshit you made up says they should be equal.

          For starters stop calling it “juxtaposition” - it’s a Product/Term. Second, as I already told you, c²=cc, so I don’t know why you’re still going on about it. I have no idea what your point is.

          In your chosen book

          You know I’ve quoted dozens of books, right?

          you can’t say shit about it

          Again I have no idea what you’re talking about.

          expands 6(ab)3 to 6(ab)(ab)(ab)

          Ah, ok, NOW I see where you’re getting confused. 6ab²=6abb, but 6(ab)²=6abab. Now spot the difference between 6ab and 6(a+b). Spoiler alert - the latter is a Factorised Term, where separate Terms have been Factorised into 1 term, the former isn’t. 2 different scenario’s, 2 different rules relating to Brackets, the former being a special case to differentiate between 6ab² and 6a²b²=6(ab)²

          P.S.

          is like arguing 1+2 is different from 2+1 because 8/1+2 is different from 8/2+1

          this is correct - 2+1 is different from 1+2, but (1+2) is identically equal to (2+1) (notice how Brackets affect how it’s evaluated? 😂) - but I had no idea what you meant by “throwing other numbers on there”, so, again, I have no idea what your point is

            Juxtaposition is key to the bullshit you made up, you infuriating sieve. You made a hundred comments in this thread about how 2*(8)2 is different from 2(8)2. Here is a Maths textbook saying, you’re fucking wrong.

            Here’s another: First Steps In Algebra, Wentworth 1904, on page 143 (as in the Gutenberg PDF), in exercise 54, question 9 reads (x-a)(2x-a)=2(x-b)2. The answer on page 247 is x=(2b2-a2)/(4b-3a). If a=1, b=0, the question and answer get 1/3, and the bullshit you’ve made up does not.

            You have harassed a dozen people specifically to insist that 6(ab)2 does not equal 6a2b2. You’ve sassed me specifically to say a variable can be zero, so 6(a+b) can be 6(a+0) can just be 6(a). There is no out for you. This is what you’ve been saying, and you’re just fucking wrong, about algebra, for children.

              Juxtaposition is key to the bullshit you made up

              Terms/Products is mathematical fact, as is The Distributive Law. Maths textbooks never use the word “juxtaposition”.

              You made a hundred comments in this thread about how 2*(8)2 is different from 2(8)2

              That’s right. 1/2(8)²=1/256, 1/2x8²=32, same difference as 8/2(1+3)=1 but 8/2x(1+3)=16

              Here is a Maths textbook saying, you’re fucking wrong

              Nope! It doesn’t say that 1/a(b+c)=1/ax(b+c). You’re making a false equivalence argument

              Here’s another:

              Question about solving an equation and not about solving an expression. False equivalence again.

              You have harassed a dozen people specifically to insist that 6(ab)2 does not equal 6a2b2

              Nope! I have never said that, which is why you’re unable to quote me saying that. I said 6(a+b)² doesn’t equal 6x(a+b)², same difference as 8/2(1+3)=1 but 8/2x(1+3)=16

              You’ve sassed me specifically to say a variable can be zero, so 6(a+b) can be 6(a+0) can just be 6(a).

              That’s right

              There is no out for you

              Got no idea what you’re talking about

              This is what you’ve been saying

              Yes

              you’re just fucking wrong

              No, you’ve come up with nothing other than False Equivalence arguments. You’re taking an equation with exponents and no division, and trying to say the same rules apply to an expression with division and no exponents, even though we know that exponent rule is a special case anyway, even if there was an exponent in the expression, which there isn’t. 🙄

                I have never said that, which is why you’re unable to quote me saying that.

                1/2(8)²=1/256

                That’s you saying it. You are unambiguously saying a(b)c somehow means (ab)c=acbc instead of abc, except when you try to nuh-uh at anyone pointing out that’s what you said. Where the fuck did 256 come from if that’s not exactly what you’re doing?

                You’re allegedly an algebra teacher, snipping about terms I am quoting from a textbook you posted, and you wanna pretend 2(x-b)2 isn’t precisely what you insist you’re talking about? Fine, here’s yet another example:

                A First Book In Algebra, Boyden 1895, on page 47 (49 in the Gutenberg PDF), in exercise 24, question 18 reads, divide 15(a-b)3x2 by 3(a-b)x. The answer on page 141 of the PDF is 5(a-b)2x. For a=2, b=1, the question and answer get 5x, while the bullshit you’ve made up gets 375x.

                Show me any book where the equations agree with you. Not words, not acronyms - an answer key, or a worked example. Show me one time that published math has said x(b+c)n gets an xn term. I’ve posted four examples to the contrary and all you’ve got is pretending not to see x(b+c)n right fuckin’ there in each one.

                  That’s you saying it

                  No it isn’t! 😂 Spot the difference 1/2(8)²=1/256 vs.

                  6(ab)2 does not equal 6a2b2

                  You are unambiguously saying a(b)^c somehow means (ab)c=ac b^c

                  Nope. Never said that either 🙄

                  except when you try to nuh-uh at anyone pointing out that’s what you said

                  Because that isn’t what I said. See previous point 😂

                  Where the fuck did 256 come from if that’s not exactly what you’re doing?

                  From 2(8)², which isn’t the same thing as 2(ab)² 🙄 The thing you want it to mean is 2(8²)

                  snipping about terms I am quoting from a textbook you posted,

                  Because you’re on a completely different page and making False Equivalence arguments.

                  you wanna pretend 2(x-b)2 isn’t precisely what you insist you’re talking about?

                  No idea what you’re talking about, again. 2(x-b)2 is most certainly different to 2(xb)2, no pretense needed. you’re sure hung up on making these False Equivalence arguments.

                  Show me any book where the equations agree with you

                  Easy. You could’ve started with that and saved all this trouble. (you also would’ve found this if you’d bothered to read my thread that I linked to)…

                  Thus, x(x-1) is a single term which is entirely in the denominator, consistent with what is taught in the early chapters of the book, which I have posted screenshots of several times.

                  I’ve posted four examples to the contrary

                  You’ve posted 4 False Equivalence arguments 🙄 If you don’t understand what that means, it means proving that ab=axb does not prove that 1/ab=1/axb. In the former there is multiplication only, in the latter there is Division, hence False Equivalence in trying to say what applies to Multiplication also applies to Division

                  all you’ve got is

                  Pointing out that you’re making a False Equivalence argument. You’re taking examples where the special Exponent rule of Brackets applies, and trying to say that applies to expressions with no Exponents. It doesn’t. 🙄 The Distributive Law always applies. The special exponent rule with Brackets only applies in certain circumstances. I already said this several posts back, and you’re pretending to not know it’s a special case, and make a False Equivalence argument to an expression that doesn’t even have any exponents in it 😂

                    From 2(8)², which isn’t the same thing as 2(ab)²

                    a=8, b=1, it’s the same thing.

                    False equivalence is you arguing about brackets and exponents by pointing to equations without exponents.

                    This entire thing is about your lone-fool campaign to insist 2(8)2 doesn’t mean 2*82, despite multiple textbook examples that only work because a(b)c is a*bc and not acbc.

                    I found four examples, across two centuries, of your certain circumstances: addition in brackets, factor without multiply symbol, exponent on the bracket. You can’t pivot to pretending this is a division syntax issue, when you’ve explicitly said 2(8)2 is (2*8)2. Do you have a single example that matches that, or are you just full of shit?
