Comment on I dunno
Cethin@lemmy.zip 17 hours agoI 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 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.
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:
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 creator of the universe made the laws of nature, which gave rise to the rules of Maths, which can be found in Maths textbooks 😂

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

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