  Then you’re just a crank who lies to thirteen-year-olds about some bullshit you made up.

  Weird then that’s in in Maths textbooks isn’t it 😂

  Both 2(8+0)2 and 2(8*1)2

  Says another person who can’t tell the difference between a(b+c) and a(bc) 🙄

  Nobody but you has this problem

  Knowing how to read Maths textbooks is a problem?? 😂 I can assure you that all my students have this same “problem”

  Real math doesn’t work differently based on how you got there

  It does if you have different expressions, such as 8/2(1+3) and 8/2x(1+3)

  B 8/2(1+3)=8/(2+6)=8/8 E DM 8/8=1 AS

  B 8/2x(1+3)=8/2x4 E DM 8/2x4=4x4=16 AS

  Different expressions, different order of evaluation, same rules of Maths (both following BEDMAS here) resulting in the different evaluations of the different expressions 🙄

    If you can simplify before distributing - and the PDFs you spam say you can - then there is no difference. You made it the fuck up.

    2(n)^2^ is 2n^2^ whether n=a+b or n=a*b=ab. If you want to square the 2, that’s (2n)^2^.

    It’s not about the multiply sign, or grouping, or division. You fooled yourself into saying 2=1.

      They say you can do that when there is Addition or Subtraction inside the Brackets. They also say you cannot Distribute over Multiplication, at all

      then there is no difference

      There is no difference between Addition and Multiplication?? 😂

      You made it the fuck up

      And yet, there it is in textbooks that were written before I was even born 😂

      2(n)2 is 2n2 whether n=a+b or n=a*b=ab

      Nope! a(b+c)=(ab+ac). a(bxc)=abc

      If you want to square the 2, that’s (2n)2.

      …or 2²xn², or 2(½n+½n)²

      It’s not about the multiply sign, or grouping, or division

      Yes it is! 😂 If there’s a Multiply or a Divide, you cannot Distribute.

      You fooled yourself into saying 2=1

      Not me! 😂

        Every textbook with an answer key says you’re full of shit.

        Physical calculators say you’re full of shit.

        Advanced math programs say you’re full of shit.

        You can keep talking, but you’re obviously just full of shit.

        At some point you’re either so deep in denial you should speak Swahili, or else being wrong on purpose is the point. The answer in either case is shut the fuck up.
