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.
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.
The definition of Division changed more than 130 years ago. a+b/c+d originally meant (a+b)/(c+d), but that limited you to one division per expression, so they changed the definition to be a+b/c+d=a+(b/c)+d, which brought it into line with all the other operators - the underlying Maths never changed, just the way we write expressions did
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.
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!
No, it actually is Algebra. The Distributive Law isn’t taught to students until they start on Algebra.
There’s no a(b+c) in Arithmetic.

You don’t think Maths textbooks are right??
is full of disinformation. Note that they literally never cite any Maths textbooks
And whichever Joe Blow My Next Door Neighbour wrote that is wrong
Algebra isn’t taught until high school
No, anything with a(b+c) is Algebra, taught in Year 7
and the rules of Algebra, which includes a(b+c)=(ab+ac). There is no such rule in Arithmetic.
It does if you’re going to argue over whether it’s Arithmetic or Algebra.
The Distributive Law is 100% part of Algebra. It’s one of the very first things taught (right after pronumerals and substitution).
I teach it. We teach it to Year 7, at the start of Algebra

The creator of the universe made the laws of nature, which gave rise to the rules of Maths, which can be found in Maths textbooks 😂
Which you said changed 130 years ago.
The definition of Division changed more than 130 years ago. a+b/c+d originally meant (a+b)/(c+d), but that limited you to one division per expression, so they changed the definition to be a+b/c+d=a+(b/c)+d, which brought it into line with all the other operators - the underlying Maths never changed, just the way we write expressions did
Ohhh, so there is a difference between what’s in math(s) books and the underlying laws of reality. When it lets you scold people.
What do you expect to happen when you call a Maths teacher wrong about Maths?
Maths teachers are ill informed about Maths?? 😂
Which therefore contradicts your argument about it being part of Arithmetic, which is taught in elementary school, Algebra isn’t

You know we’re talking about Year 7 Maths, right? 😂
but NOT The Distributive Law, which is taught in high school, in Algebra
You said “I don’t think you’re right”, and followed it up with “Ill informed”, to a Maths teacher.
And you were wrong about that too
What you mean is you clearly can’t rebut any of it
I know everything about high school Maths - I teach it
There you go again calling a Maths teacher wrong about Maths 😂
You think Maths textbooks use very strange logic??
read this then. Contains Maths textbooks

Sorry, it most definitely does when it comes to how English is used in Maths
The way we say Mathematical things is 100% Maths
I can improve some badly written textbooks. Probably every Maths teacher can.
Yes, ones who haven’t looked in the textbook which seems to be the case with a lot of unqualified U.S. Maths teachers
Probably the content of every book they teach 🙄
Teachers do. It comes from teaching the same thing year after year after year
Yes it is! 😂
It’s Mathematical English
Do you see words in Maths textbooks? And the definitions of them? 🙄
Why you keep insisting that Maths textbooks are wrong
And NOT being in any arithmetic book means it’s not part of Arithmetic 🙄
Yep, both Arithmetic and Algebra, as opposed to a(b+c) which is only in Algebra books.
Says person who can’t cite any Arithmetic books it’s in 🙄
Already gave it in the previous post… which you didn’t look at 🙄
