  Solving brackets does not include forced distribution

  Yes it does! 😂

  Image

  Juxtaposition means multiplication,

  No, 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…

  Image

  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

  Image

  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! 😂

  while there are still multiple terms inside

  As in 2(8)=(2x8) 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

  Image

  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, wrongly calls Products “Multiplication”, and claimed that I invented a rule that is in an 1898 textbook! 🤣

  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.

    Another example: stemjock.com/STEM Books/…/OSCACh1s1e32.pdf

    Alternatively, here is another example: kingphilip.org/…/Supplemental_Topics_from_Algebra…

      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.

        If 5(4)^2^ is 5*16 then 2(8)^2^ is 2*64.

        I get a free hoagie.
