  Nowhere in your “proof” screenshots does it say anything about distribution being part of the brackets step

  Which step is first? Brackets. What do they do first in 5(36)/9? The Brackets.

  What does the other textbook do with bc? Puts it in Brackets. Which step is fist in order of operations? Brackets 🙄 What do they end that page with? “those who study algebra are required to make their calculations conform to these laws”. You seriously need to work on your comprehension that I need to explicitly spell out to you what the textbooks say

  Distribution is a method that can help solve equations

  The Property is. The Law is a rule which literally must be obeyed, as per Maths textbooks 🙄

  it isn’t required

  Yes it is! That’s why it’s a Law 😂

  If you have 2(3+5) you’re free to solve it as 23+25 or as 2*8

  Nope, neither

  1/2(3+5)=1/(6+10)

  1/2x3+2x5=3/2+10 WRONG ANSWER

  1/2x8=8/2=4 WRONG ANSWER

  Welcome to why it must be in brackets, as per Maths textbooks 🙄

  That is because juxtaposition means multiplication and nothing else

  says person who can’t cite any Maths textbook that says that. Nope! It means it’s a Term/Product, the result of a Multiplication (or Factorisation), and nothing else…

  Note that it never used the word Multiplication at all in that definition 🙄

  Math textbooks almost universally will either use clear brackets or simply write divisions in 2 lines

  or an obelus or slash on one line

  which avoids the confusion altogether

  Only people who don’t remember the rules of Maths are confused about it. Students have no trouble with it.

    Here is math for kids www.mathsisfun.com/…/distributive-law.html

    Distributive law means you are allowed to distribute, not that you must distribute. I’m so sorry for the amount of effort you’re futilely putting into this lmao. Nowhere in all your sources and screenshots is it stated you must distribute, and thus the entire argument breaks down.

      Yep, that’s about The Distributive Property too 🙄 Every time Multiplication gets mentioned, you know they’re talking about the Property, since the Law has no multiplication in it, but The Distributive Property of Multiplication over Addition does

      Distributive law means you are allowed to distribute

      No, the Property does. The Law tells you that you literally must Distribute.

      not that you must distribute

      Because The Law says that, hence why it’s a Law 🙄

      I’m so sorry for the amount of effort you’re futilely putting into this lmao

      says someone who can’t even tell the difference between the Property and the Law 😂

      Nowhere in all your sources and screenshots is it stated you must distribute

      Yes it does liar

      thus the entire argument breaks down

      Not for people who know how to read 😂

        You must not distribute brother, lay it to rest lmao. It’s optional. Google distributive law and find me one source saying it’s imperative to distribute - there’s none. You can even confirm this is true yourself with simple examples like the ones I’ve mentioned above.
