STILL can’t admit you’re wrong then 😂 I guess you never bothered looking in any Maths textbooks since last time then (or you did and don’t want to admit you found out you were wrong)
You are the brickest wall on lemmy. Either out of undiagnosed neurodivergence or some aggravating character gimmick, you pretend there is one true way to do a thing, except when you don’t. The commutative property means addition can happen in any order! But multiplication and distribution are totally different (despite getting the same goddamn answer due to the commutative property) and you will never ever shut the fuck up about splitting that hair.
It’s dogma. You’ve internalized one set of rigid instructions, and declared them the rules of all mathematics, to the point you insist Reverse Polish Notation has parentheses. It fucking doesn’t. It literally cannot. Yet it’s an equally valid way to write and do math. It gets the same results, despite distribution being impossible. Last time I tried wedging this uneniable fact through any gap in your mortar, you smugly declared you’d found a way… and then explained multiplication, not distribution. Zero self-awareness. To this day, you are trying to be smug about a time you proudly contradicted yourself.
I feel sorry for students who can’t just tell you:
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? 😂

I don’t think you understand mathematics above the 7th-grade level you brag about teaching. No bona fides will excuse how you’ve acted; you have to be better. On the internet nobody knows you’re a dog, and you act like a child cosplaying a teacher that students hate.
RPN does not have parentheses, any more than standard notation can have a stack. The concept does not exist. Yet both forms of equation are equally valid, but different - in the same way as peasant multiplication versus new-math multiplication. I’m not saying this for your sake because you’re a broken robot. But since you’re spamming everyone in this two-week-old thread, some of them are going to scroll through wondering ‘is this schmuck for real?,’ and they deserve to know exactly how small-minded and stubborn you are.
You’re basically out here demanding that multiplication can only be done in the peasant method, so if someone’s explaining it without a list of doubled numbers, they ‘can’t admit they’re wrong.’ So you’re going to henpeck them one line at a time, ignoring the many ways they try to politely explain you’re being a pedantic troll, and pounding books that reflect knowledge as if they define knowledge, until they all give up trying to spoon-feed you your own visible failure to teach anyone anything. Nobody’s walking away from these interactions like ‘oh thanks, good to know, that’s perfectly clear now.’ It’s wall-to-wall ‘I don’t think you’re as smart as you think you are’ and ‘you’re really missing the point’ and ‘if it always gets the same answer then there’s no meaningful difference.’
Yet tour dogmatism is so blatant that you’re assigning Buddha nature to parentheses. Your philosophy cannot comprehend a math notation where you’re even merely overreaching, let alone mistaken - so parentheses flit into being, somewhere in a stack operation between two numbers at a time. 1 2 + 3 * is not an equation with parentheses. Order of operations is baked into the order of operands. The first time I explained this to you, you had never heard of it. Yet you immediately asserted you’d found something missed by all all other people, sites, and indeed holy texts maths books.
You are a crank. Trying to ‘no u’ about your absence of self-awareness does not work, because you didn’t predict me showing up to harass people with grade-school math while not listening. What you’re doing is troll behavior. If this is how you teach children, it’s enforced learning by rote, and their understanding of even basic mathematics is permanently hobbled by your smile-and-repeat-yourself rhetorical style.
