    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 first 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, when solving expressions, 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

        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.

          • You must not distribute brother

            Literally a Law of Maths, but go ahead and stay in Denial about it 😂

            It’s optional

            You think the word “must” means it’s optional?? 😂

            Google distributive law and find me one source saying it’s imperative to distribute

            Go through Maths textbooks and find me one which says it isn’t, or alternatively go through dictionaries and find me one that says “must” means “optional” 😂

            there’s none

            He says, when I’ve already posted multiple textbooks which say it is 😂

            You can even confirm this is true yourself with simple examples like the ones I’ve mentioned above

            I’ve confirmed it with Maths textbooks - you know, those things you refuse to look in because you know they prove you are wrong 😂 BTW your “example above” was about The Distributive Property, as I already pointed out to you at the time

              Bro directly after what you underlined it says “if you want to remove the brackets” lol. Selective reading much? “If” means optional. You are free to solve what’s inside the brackets first, before multiplying it with what’s outside.

              Also, the link I posted is literally titled “distributive law”, not property. You realize a law can have conditions, right?

              Quick quiz for you: what’s the result of 2(3+5)² ?

              • Bro directly after what you underlined it says “if you want to remove the brackets”

                Yep, that’s right, and removing brackets is the first step in order of operations 😂

                Selective reading much?

                By you apparently.

                “If” means optional

                So… you’re telling me that the “B” step in BEDMAS, and the “P” step in PEMDAS, is optional? I don’t have to remove Brackets?? 😂 Better go back to school dude

                You are free to solve what’s inside the brackets first, before multiplying it with what’s outside

                Yep, but inside the brackets, as per the text you can see in the screenshot 😂

                5(8-5)=(5x8-5x5)=(40-25)=15

                5(8-5)=5(3)=(5x3)=15 <== Multiplication inside the Brackets, as per The Distributive Law

                same answer both ways 😂

                the link I posted is literally titled “distributive law”, not property

                But has a multiply sign in it, thus proving it is the Property that they are talking about - The Distributive Property of Multiplication over Addition to call it by it’s full name

                You realize a law can have conditions, right?

                You realise it literally must be obeyed, right? The condition that The Distributive Law has, is “A number or letter next to a Bracket”, direct quote from the textbook, hence a(b+c)=(ab+ac), and not ax(b+c) since the a is not next to the bracket in that case
