    That’s not even an equation, just basic arithmetic

      Technically not algebra, right? Algebra is where you move things around and solve for variables, and that kind of thing. This is just arithmetic.

          I don’t think you’re right. The wiki page literally uses a similar equation as an example of “elementary arithmetic.” It also uses a similar one, but with variables, as an example in “elementary algebra.” That implies that yes, this is arithmetic, and the introduction of variables is what makes it algebra.

          It doesn’t matter what course finally teaches it to you. That could be just out of convenience, not by definition part of that domain. It’s been ages since I took it, though I could swear I learned this in pre-algebra (meaning before algebra), or earlier. I could be wrong on this though. Again, it’s been a very long time.

          • 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.

              • 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

                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.

      Fair enough, I’ve heard “math problem” and “math equation” used interchangeably.

      Also you would be surprised how many people do not know basic algebra, at least in the US rofl
