    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?

    • a=8, b=1, it’s the same thing

      No it isn’t! 😂 8 is a single numerical factor. ab is a Product of 2 algebraic factors.

      False equivalence is you arguing about brackets and exponents

      Nope. I was talking about 1/a(b+c) the whole time, as the reason the Distributive Law exists, until you lot decided to drag exponents into it in a False Equivalence argument. I even posted a textbook that showed more than a century ago they were still writing the first set of Brackets. i.e. 1/(a)(b+c). i.e. It’s the FOIL rule, (a+b)(c+d)=(ac+ad+bc+bd) where b=0, and these days we don’t write (a)(b+c) anymore, we just write a(b+c), which is already a single Term, same as (a+b)(c+d) is a single term, thus doesn’t need the brackets around the a to show it’s a single Term.

      3(x-y) is a single term

      This entire thing is about your lone-fool campaign

      Hilarious that all Maths textbooks, Maths teachers, and most calculators agree with me then, isn’t it 😂

      insist 2(8)2 doesn’t mean 2*82,

      Again, you lot were the ones who dragged exponents into it in a False Equivalence argument to 1/a(b+c)

      I found four examples, across two centuries

      None of which relate to the actual original argument about 1/a(b+c)=1/(ab+ac) and not (b+c)/a

      You can’t pivot to pretending this is a division syntax issue

      I’m not pivoting, that was the original argument. 😂 The most popular memes are 8/2(2+2) and 6/2(1+2), and in this case they removed the Division to throw a curve-ball in there (note the people who failed to notice the difference initially). We know a(b+c)=(ab+ac), because it has to work when it follows a Division, 1/a(b+c)=1/(ab+ac). It’s the same reason that 1/a²=1/(axa), and not 1/axa=a/a=1. It’s the reason for the brackets in (ab+ac) and (axa), hence why it’s done in the Brackets step (not the MULTIPLY step). It’s you lot trying to pivot to arguments about exponents, because you are desperately trying to separate the a from a(b+c), so that it can be ax(b+c), and thus fall to the Multiply step instead of the Brackets step, but you cannot find any textbooks that say a(b+c)=ax(b+c) - they all say a(b+c)=(ab+ac) - so you’re trying this desperate False Equivalence argument to separate the a by dragging exponents into it and invoking the special Brackets rule which only applies in certain circumstances, none of which apply to a(b+c) 😂

      2(8)2 is (2*8)2.

      That’s right

      are you just full of shit?

      says the person making False Equivalence arguments. 🙄 Let me know when you find a textbook that says a(b+c)=ax(b+c), otherwise I’ll take that as an admission of being wrong that you keep avoiding the actual original point that a(b+c) is a single Term, as per Maths textbooks

        3(x-y) is a single term…

        So is 3xy, according to that textbook. That doesn’t mean 3xy2 is 9*y2*x2. The power only applies to the last element… like how (8)22 only squares the 2.

        Four separate textbooks explicitly demonstrate that that’s how a(b)c works. 6(ab)3 is 6(ab)(ab)(ab), not (6ab)(6ab)(6ab). 3(x+1)2 for x=-2 is 3, not 9. 15(a-b)3x2 doesn’t involve coefficients of 3375. 2(x-b)2 has a 2b2 term, not 4b2. If any textbook anywhere shows a(b)c producing (ab)c, or x(a-b)c producing (xa-xb)c, then reveal it, or shut the fuck up.

        2(ab)2 is 2(ab)(ab) the same way 6(ab)3 is 6(ab)(ab)(ab). For a=8, b=1, that’s 2*(8*1)*(8*1).

          So is 3xy

          That’s right

          That doesn’t mean 3xy2 is 9y2x2.

          That’s right. It means 3abb=(3xaxbxb)

          The power only applies to the last element

          Factor yes, hence the special rule about Brackets and Exponents that only applies in that context

          like how (8)22 only squares the 2

          It doesn’t do anything, being an invalid syntax to follow brackets immediately with a number. You can do ab, a(b), but not (a)b

          not (6ab)(6ab)(6ab)

          Yep, as opposed to 6(a+b), which is (6a+6b)

          3(x+1)2 for x=-2 is 3, not 9

          No it isn’t. See previous point. Do we have an a(b+c), yes we do. Do we have an a(bc)²? No we don’t.

          2(x-b)2 has a 2b2 term

          No, it has a a(b-c) term, squared

          shut the fuck up

          says someone still trying to make the special case of Exponents and Brackets apply to a Factorised Term when it doesn’t. 😂 I’ll take that as your admission of being wrong about a(b+c)=ax(b+c) then. Thanks for playing

          For a=8, b=1, that’s 2*(81)(8*1).

          Only if you had defined it as such to begin with, otherwise the Brackets Exponents rule doesn’t apply if you started out with 2(8)², which is different to 2(8²) and 2(ab)²

          …and there’s still no exponent in a(b+c) anyway, Mr. False Equivalence

            There is no special case. You made it up by confusing yourself about “dismissing a bracket.” To everyone else in the world, brackets are just another term. Several of the textbooks I’ve linked will freely juxtapose brackets and variables before or after, because it makes no difference.

            Here’s yet another example, PDF page 27: (6+5)x+(-2+10)y. And that’s as factorization. This Maths textbook you plainly didn’t read was published this decade. Still waiting on any book ever that demonstrates your special bullshit.

            7bx with b=(m+n) becomes 7(m+n)x and it’s the same damn thing. Splitting it like 7xm+7xn is no different from splitting (m+n)/7 into m/7+n/7. Brackets only happen first because they have to be reduced to a single term. A bracket with one number is not “unsolved” - it’s one number. Squaring a bracket with one number is squaring that number.

            The base of an exponent is whatever’s in the symbols of inclusion. Hence: 6(ab)3 = 6(ab)(ab)(ab).

            No, it has a a(b-c) term, squared

            It has a (b-c) term, squared. The base of an exponent is whatever’s in the symbols of inclusion. See page 121 of 696, in the Modern Algebra: Structure And Method PDF you plainly got from Archive.org. “In an expression such as 3a2, the 2 is the exponent of the base a. In an expression such as (3a)2, the 2 is the exponent of the base 3a, because you enclosed the expression in a symbol of inclusion.” You will never find a published example that makes an exception for distribution first.

            On the page before your screenshot - 116 of 696 - this specific Maths textbook refers to both 8x7 and 8(7) as “symbols of multiplication.” It’s just multiplication. It’s only ever multiplication. It’s not special, you crank. 8(7) is a product identical to 8x7. Squaring either factor only squares that factor.

            Only if you had defined it as such to begin with

            Variables don’t work differently when you know what they are. b=1 is not somehow an exception that isn’t allowed, remember?

            There’s an exponent in 2(8)2 and it concisely demonstrates to anyone who passed high school that you can’t do algebra.
