Yeah, but even worse, you’re just talking about schools

I'm talking about anyone at all in the U.S. is allowed to teach Maths without any Maths qualifications

You forgot about all the kids being home schooled

That happens in other countries too, and yet it's the U.S. which has been sliding down the world rankings for more than a decade, the country that doesn't require Maths teachers to have Maths qualifications.

Also, it’s kinda obvious the rules of math aren’t different in the US

That's right, as proven by U.S. Maths textbooks

If people don’t know how to use math properly, the issue clearly is the education and not math itself

Partly right. there's also people who just outright forgot the rules.

only one valid notation

Only one valid set of rules you mean. Notation varies by country

I warned folks about your cocksure confusion of notation and rules

says person who is confused about the difference between notation and rules 😂

You’re so confused about notation versus rules

Nope! That's you

RPN must have parentheses, somewhere, somehow, because they’re in the One True

Rules There you go confusing notation with rules again

I don’t think you understand being wrong, as a concept

says person who refuses to look in Maths textbooks 😂

Your brain slides right off it and circles back to a sequence of words that lets you be smug

And here you are writing a bunch of words and no Maths textbooks 😂

Probably the part where you said how we write expressions is different from the underlying maths

Yep, the underlying Maths is the same everywhere, because the rules are universal, but different countries have different notations, it's still the same Maths

Because words mean things

And you seem to be having trouble understanding the difference between "notation" and "rules"

Ohhh, so there is a difference between what’s in math(s) books and the underlying laws of reality

No, and I have no idea where you got that idea! 😂

You already said that to me

And you're still ignoring it

found the Commonwealther

Or more precisely, the non-USer 😜

I’m talking programming languages

Written by people who forget the order of operations rules, hence MathGPT is the only e-calc which gives correct answers.

We are not the same

Yep, as well as being a programmer I'm also a Maths teacher

Most languages throw a syntax error if the multiplication symbol is missing

See first point

You are the brickest wall on lemmy

Says person who hasn't looked this up in a Maths textbook 😂

Either out of undiagnosed neurodivergence or some aggravating character gimmick

Neither, I'm a Maths teacher

you pretend there is one true way to do a thing

There's no pretending involved, it's in Maths textbooks

The commutative property means addition can happen in any order

Yep, and??

But multiplication and distribution are totally different

Nope! They can also be done in any order

you will never ever shut the fuck up about splitting that hair

Got no idea who you think you're talking to, but I never said Multiplication and Division are different

It’s dogma

No, it's the rules of Maths as found in Maths textbooks 😂

You’ve internalized one set of rigid instructions

ALL Mathematicians have, if you're going to put it like that.

declared them the rules of all mathematics

As found in Maths textbooks

to the point you insist Reverse Polish Notation has parentheses

It adds them in the background, so that you don't have to - if it didn't it would return wrong answers - you not having to type them in doesn't mean they aren't getting added

It literally cannot

...give correct answers without putting each paired operation into brackets

Yet it’s an equally valid way to write and do math

and obeys the EXACT SAME RULES 🙄

It gets the same results

because it obeys the same rules 🙄

despite distribution being impossible

Not impossible at all. Someone even wrote it in one of the other comments! 😂

Last time I tried wedging this uneniable fact through any gap in your mortar

you found there were no gaps 😂

you smugly declared you’d found a way

And as these very comments show, I'm not the only one to have done so! 😂

then explained multiplication, not distribution

No, Distribution.

Zero self-awareness

Well, you have zero awareness of what's in Maths textbooks anyway 😂

To this day, you are trying to be smug about a time you proudly contradicted yourself

I have never contradicted myself. You calling Distribution "Multiplication" doesn't make it Multiplication.

I feel sorry for students who can’t just tell you

My students do very well in their exams. How about you? 😂

Go away, patience vampire

Still can't admit you were wrong then 🙄

I don’t know why, but this was intuitively my first approach

Because that's what we teach students to do, though technically it should be (xy-xz)

Because there is no question

So Maths test says "2+3 ____", and you write "that's not a question" on the blank line?? 😂

Because people never use that after they learn fractions,

Yes they do, because not every division is a fraction

order of appearance is ‘the rule’ when commutative properties apply

That's because students often make mistakes with signs when they do it in a different order, so we tell them to stick to left to right
