They’re definitely not

Says person who definitely can't give a single example of any that aren't 🙄

[–] SmartmanApps@programming.dev -2 points 3 months ago

Just patently untrue,

Maths textbooks are patently untrue?? 😂 I guess you think Earth is flat too

If you believe the article is incorrect, submit your corrections to Wikipedia

You know they've rejected corrections by actual Maths Professors right? Just look for Rick Norwood in the talk section. Everyone who knows Maths knows Wikipedia is wrong, and looks in the right place to begin with - Maths textbooks

Take it up with Berkeley then

What for? You're only the second person ever to have quoted him. You're not the first person to refuse to look in Maths textbooks though 🙄

I don’t think you understand mathematics above the 7th-grade level you brag about teaching

I don't think you understand any of it, not even Year 7

No bona fides will excuse how you’ve acted; you have to be better

says person who refuses to look in Maths textbooks

RPN does not have parentheses

in the foreground. In the background it does or it would give wrong answers. You understand that apps can do things that you don't see, right??

but different

Only the notation is different, the rules are the same

they deserve to know exactly how small-minded and stubborn you are

says the person who refuses to look in Maths textbooks 😂

as if they define knowledge

Textbooks do indeed define the notation and rules. 1+1=2 is defined as the notation to use to show that I had 1 thing and now I have 2 things

your own visible failure to teach anyone anything

says person ignoring all the people who actually did learn from me. That would be the people who are open to being wrong about how they thought it was done

Nobody’s walking away from these interactions like ‘oh thanks, good to know, that’s perfectly clear now.’

Yes they are! 😂

you’re assigning Buddha nature to parentheses

No, just literal textbook definition, which you refuse to look at 😂

1 2 + 3 * is not an equation with parentheses

So the app adds them in the background. Do you think apps don't know how many "a" you're talking about if you don't write 1a? Guess what, it knows in the background that a=1a, and that the 1 in 1-2-3 is +1, etc. Not typing them in doesn't mean they aren't being added

The first time I explained this to you, you had never heard of it.

yet again you seem to have me confused with someone else. I have no idea what you're talking about

You are a

Maths teacher

Trying to ‘no u’ about your absence of self-awareness does not work

says person who refuses to look in Maths textbooks

because you didn’t predict me

gaslighters gonna gaslight - there's nothing unpredictable about that

What you’re doing is

teaching the rules of Maths

If this is how you teach children, it’s enforced learning by rote

No it isn't, because they, having seen it also in the textbook, understand how it works

their understanding of even basic mathematics is permanently

improved, because they don't sit there going "Nah nah nah, nah nah nah, I'm not listening and not looking in the textbook!" 😂

The rules are socially agreed upon

Nope! Universal laws.

They are not a mathematical truth.

Yes they are! 😂

There is nothing about the order of multiple different operators in the definition of the operators themselves

That's exactly where it is. 2x3 is defined as 2+2+2, therefore if you don't do Multiplication before Addition you get wrong answers

you can order those however you like.

No you can't! 😂 2+3x4=5x4=20, Oops! WRONG ANSWER 😂

All that matters is just what calculation it is that you’re after

And if you want the right answer then you have to obey the order of operations rules

[–] SmartmanApps@programming.dev 0 points 3 months ago (5 children)

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.

[–] SmartmanApps@programming.dev 0 points 3 months ago (2 children)

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 😂

[–] SmartmanApps@programming.dev -3 points 3 months ago (134 children)

Nope, that’s wrong

You think Maths textbooks are wrong?? 😂

See https://www.wolframalpha.com/input?i=10%2F2%282%2B3%29 for reference

See Maths textbooks for reference 😂

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"

[–] SmartmanApps@programming.dev -2 points 3 months ago

Post picture declaiming brackets as a multiplication symbol,

What do you think the "B" step in BEDMAS is for?? 😂

proceeds to solve the problem to the exact same solution using distributive law to

Distribute the coefficient over the terms inside the brackets

Fucking genius

Says someone who can't tell the difference between Distributing, 2(1+3)=(2+6), and Multiplication, 2x(1+3)=2x4, 1/(2+6)=(1/8), 1/2x4=2

[–] SmartmanApps@programming.dev 0 points 3 months ago (6 children)

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! 😂
