• I don’t think you’re right

    You don’t think Maths textbooks are right??

    The wiki page

    is full of disinformation. Note that they literally never cite any Maths textbooks

    as an example of “elementary arithmetic.”

    And whichever Joe Blow My Next Door Neighbour wrote that is wrong

    as an example in “elementary algebra.”

    Algebra isn’t taught until high school

    That implies that yes, this is arithmetic,

    No, anything with a(b+c) is Algebra, taught in Year 7

    the introduction of variables is what makes it algebra

    and the rules of Algebra, which includes a(b+c)=(ab+ac). There is no such rule in Arithmetic.

    It doesn’t matter what course finally teaches it to you

    It does if you’re going to argue over whether it’s Arithmetic or Algebra.

    not by definition part of that domain

    The Distributive Law is 100% part of Algebra. It’s one of the very first things taught (right after pronumerals and substitution).

    It’s been ages since I took it

    I teach it. We teach it to Year 7, at the start of Algebra

      You’re very rude. Also, Ill informed, and you think you’re smarter than you are. For example, this:

      as an example in “elementary algebra.”

      Algebra isn’t taught until high school

      Elementary doesn’t mean elementary school. Do you think elementary particles are the ones they teach you in elementary school? Lol. Elementary means fundamental or basic.

        The clouds could part, revealing an unmistakable divine presence, where a herald of angels trumpet, and the creator of the universe tells this guy he’s being a hypocritical crank, and he’d bicker until god himself said “Stuff this” and moved on.

      • You’re very rude

        What do you expect to happen when you call a Maths teacher wrong about Maths?

        Ill informed

        Maths teachers are ill informed about Maths?? 😂

        Elementary means fundamental or basic

        Which therefore contradicts your argument about it being part of Arithmetic, which is taught in elementary school, Algebra isn’t

          Maths teachers are ill informed about Maths?? 😂

          Dude, there are math geniuses, who were powerhouses in the field, who were wrong about some things. Do you think you’re above them?

          Which therefore contradicts your argument about it being part of Arithmetic, which is taught in elementary school, Algebra isn’t

          I don’t think you understood that. Elementary particles are taught in undergrad physics, not elementary school. They’re elementary because they’re fundamental, not because of when they’re taught. Elementary school teaches you the fundamentals to your future education. That’s why it’s called that, not because they teach you everything that uses the word “elementary.” Also, many things are fundamental (elementary) to their fields that won’t be taught to elementary school students. The sharing a word does not make them related.

          What do you expect to happen when you call a Maths teacher wrong about Maths?

          I didn’t say you were wrong about math. I said you were wrong about English that is used in relation to math. Clearly this isn’t a strong suit of yours, and that’s fine. However, stop acting like you know everything, because you clearly don’t. You’re using some very strange logic to argue you’re right, and it doesn’t make any sense.

          • Do you think you’re above them?

            You know we’re talking about Year 7 Maths, right? 😂

            Elementary school teaches you the fundamentals to your future education

            but NOT The Distributive Law, which is taught in high school, in Algebra

            I didn’t say you were wrong about math

            You said “I don’t think you’re right”, and followed it up with “Ill informed”, to a Maths teacher.

            I said you were wrong about English that is used in relation to math

            And you were wrong about that too

            Clearly this isn’t a strong suit of yours

            What you mean is you clearly can’t rebut any of it

            However, stop acting like you know everything

            I know everything about high school Maths - I teach it

            you clearly don’t

            There you go again calling a Maths teacher wrong about Maths 😂

            You’re using some very strange logic to argue you’re right

            You think Maths textbooks use very strange logic??

            it doesn’t make any sense

            read this then. Contains Maths textbooks

              You said “I don’t think you’re right”, and followed it up with “Ill informed”, to a Maths teacher.

              About pedantics, not math. Sorry, your realm does not extend into English. Even if you were one of the great mathematicians of our time (which I suspect your not, but I don’t know you) this still isn’t the same domain. It’s tangential to mathematics, but it isn’t mathematics.

              I know everything about high school Maths - I teach it

              Everything, huh? There’s absolutely nothing you can improve on? Has a teacher ever been wrong (or just uninformed) about a topic in a subject they teach? Does every English teacher know the content of every book? You can be a great teacher and still not know everything. No one knows everything about a subject, even when they’re complete experts. Anyway, this isn’t your subject! This is English, not math. Do you see any formulas, proofs, or equations in these comments?

              You think Maths textbooks use very strange logic??

              What don’t you get? It being in an algebra textbook does not limit it to the realm of algebra. Numbers are in that textbook too, yet they aren’t exclusive to algebra. I’m reasonably confident that your textbook, where it teaches this, does not say “this is a part of algebra, and no other domain.” If I’m wrong, I’d love to see the citation.

              Anyway, unless you provide that proof at the end there, I’m done with this conversation. Goodbye and I hope you have a good time teaching math!

              • Sorry, your realm does not extend into English

                Sorry, it most definitely does when it comes to how English is used in Maths

                It’s tangential to mathematics, but it isn’t mathematics

                The way we say Mathematical things is 100% Maths

                There’s absolutely nothing you can improve on?

                I can improve some badly written textbooks. Probably every Maths teacher can.

                Has a teacher ever been wrong (or just uninformed) about a topic in a subject they teach?

                Yes, ones who haven’t looked in the textbook which seems to be the case with a lot of unqualified U.S. Maths teachers

                Does every English teacher know the content of every book?

                Probably the content of every book they teach 🙄

                No one knows everything about a subject

                Teachers do. It comes from teaching the same thing year after year after year

                Anyway, this isn’t your subject!

                Yes it is! 😂

                This is English, not math

                It’s Mathematical English

                Do you see any formulas, proofs, or equations in these comments?

                Do you see words in Maths textbooks? And the definitions of them? 🙄

                What don’t you get?

                Why you keep insisting that Maths textbooks are wrong

                It being in an algebra textbook does not limit it to the realm of algebra

                And NOT being in any arithmetic book means it’s not part of Arithmetic 🙄

                Numbers are in that textbook too

                Yep, both Arithmetic and Algebra, as opposed to a(b+c) which is only in Algebra books.

                If I’m wrong, I’d love to see the citation

                Says person who can’t cite any Arithmetic books it’s in 🙄

                Anyway, unless you provide that proof at the end there

                Already gave it in the previous post… which you didn’t look at 🙄

                  OK, I said I was done, but one last one.

                  And NOT being in any arithmetic book means it’s not part of Arithmetic 🙄

                  Here is a distributive law lesson for grade 4. Here’s another, and another. My search was just “when is the distributive law taught in schools”. These were the first results.

                  It being used in an algebra course doesn’t mean it’s in the domain of algebra. Algebra is also used in calculus, but algebra isn’t the domain of calculus, correct?

                  It’s algebra when it’s using variables, and you’re solving for an equation. 2(3+4) is arithmetic. 2(x+4)=0 is algebra.

                  Arithmetic: a branch of mathematics that deals usually with the nonnegative real numbers including sometimes the transfinite cardinals and with the application of the operations of addition, subtraction, multiplication, and division to them.

                  Algebra: [A] branch of mathematics in which arithmetical operations and formal manipulations are applied to abstract symbols rather than specific numbers.

                  Note: Algebra includes the use of arithmetic. It being used in algebra does not mean it is part of algebra.

                  • Here is a distributive law lesson for grade 4

                    That’s the Distributive Property actually. The dead giveaway is the multiply sign, as in “The Distributive Property of Multiplication over Addition”. There’s no Multiply sign in The Distributive Law, a(b+c)=(ab+ac)

                    Here’s another, and another.

                    Also The Distributive Property. “The distributive law says that multiplying a number by a group of numbers added together is the same as doing each multiplication separately” - no, the Distributive Property says that.

                    These were the first results

                    Welcome to the problem with using the internet and not looking at Maths textbooks

                    It being used in an algebra course doesn’t mean it’s in the domain of algebra

                    It being taught in Algebra most certainly does mean it’s in the domain of Algebra

                    Algebra is also used in calculus, but algebra isn’t the domain of calculus, correct?

                    It’s all Algebra. You can’t do Calculus if you haven’t learnt Algebra yet, just like you can’ do a(b+c) if you haven’t learnt Algebra yet.

                    It’s algebra when it’s using variables

                    and the rules of Algebra, like a(b+c)=(ab+ac). Arithmetic doesn’t have any rules that aren’t in Algebra, but Algebra does have rules which aren’t in Arithmetic.

                    and you’re solving for an equation

                    I can solve 1+1= without using Algebra

                    2(3+4) is arithmetic

                    Nope, it’s Algebra

                    2(x+4)=0 is algebra

                    Yep, now substitute x=3 in 2(x+4) and tell me what you get 😂

                    the application of the operations of addition, subtraction, multiplication, and division to them

                    Yep. Notice how Distribution was not mentioned?? 😂

                    and formal manipulations

                    Yep, such as a(b+c)=(ab+ac)

                    rather than specific numbers

                    Soooo, a+b is Algebra, but 2a+3b+4 isn’t Algebra, because it has specific numbers in it?? 😂

                    Note: Algebra includes the use of arithmetic

                    Yep, it sure does.

                    t being used in algebra does not mean it is part of algebra

                    NOT being used in Arithmetic means it’s not part of Arithmetic. 🙄 You know we’ve only had Brackets in Maths for 300 years, and that Arithmetic is much older than that, right?
