    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

                Exponents come after brackets, so I’m curious to see how you solve that with your logic lol. It has an obvious correct solution, which is 128, but you need to distribute in the brackets step, which comes before exponents, so let’s see what you do with it lmao.

                • Exponents come after brackets

                  That’s right

                  so I’m curious to see how you solve that with your logic

                  Ummm, you do the brackets and then the exponent. Not sure what you find unclear about that

                  It has an obvious correct solution

                  The one where you do the brackets before the exponent

                  which is 128

                  Nope! You can only get that by doing the exponent before the brackets, which is against the order of operations rules. Or did you wrongly add a multiply sign before the brackets - that also yields a different answer

                  you need to distribute in the brackets step

                  That’s right, so why did you do the exponent first?

                  which comes before exponents,

                  That’s right. So why did you do the exponent first?

                  so let’s see what you do with it

                  Brackets before exponents, as already established 🙄

                    Ok bro now find an expression solver that verifies your solution. I tried Wolfram Alpha, Google, and others, and they all return 128. So either you’re wrong, or all people who make these tools professionally are wrong. Not trying to be offensive, but I know where I’m putting my money.

                    To be clear, the reason you’re wrong is because distribution is not part of the brackets step. Brackets are solved before exponents, resulting in 2(8)². Remove the brackets and then it’s 2*8²
