Comment on I dunno
SmartmanApps@programming.dev 1 day agoI 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.
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:
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 😂

Which you said changed 130 years ago.

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.

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
