Comment on I dunno
SmartmanApps@programming.dev 3 days agoinsist mathematics has exactly one perfect unambiguous syntax,
It sure does! 😂
2*(1+3) is somehow different from 2(1+3)
Yep, one is Multiplication - 2x3 - the other is The Distributive Law - (2x1+2x3) - both easily found in Maths textbooks

Fuck off.

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:
Go away, patience vampire.

Says person who hasn’t looked this up in a Maths textbook 😂
Neither, I’m a Maths teacher
There’s no pretending involved, it’s in Maths textbooks
Yep, and??
Nope! They can also be done in any order
Got no idea who you think you’re talking to, but I never said Multiplication and Division are different
No, it’s the rules of Maths as found in Maths textbooks 😂
ALL Mathematicians have, if you’re going to put it like that.
As found in Maths textbooks
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
…give correct answers without putting each paired operation into brackets
and obeys the EXACT SAME RULES 🙄
because it obeys the same rules 🙄
Not impossible at all. Someone even wrote it in one of the other comments! 😂
you found there were no gaps 😂
And as these very comments show, I’m not the only one to have done so! 😂
No, Distribution.
Well, you have zero awareness of what’s in Maths textbooks anyway 😂
I have never contradicted myself. You calling Distribution “Multiplication” doesn’t make it Multiplication.
My students do very well in their exams. How about you? 😂
Still can’t admit you were wrong then 🙄
