  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

        Ok bro so answer my question what’s the result of the expression I wrote above?
