40500 readers
774 users here now
A Fediverse community for open-ended, thought provoking questions
Rules: (interactive)
1) Be nice and; have fun
Doxxing, trolling, sealioning, racism, toxicity and dog-whistling are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them
2) All posts must end with a '?'
This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?
3) No spam
Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason
Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either !asklemmyafterdark@lemmy.world or !asklemmynsfw@lemmynsfw.com.
NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.
If you have any questions regarding the site itself or would like to report a community, please direct them to Lemmy.world Support or email info@lemmy.world. For other questions check our partnered communities list, or use the search function.
6) No US Politics.
Please don't post about current US Politics. If you need to do this, try !politicaldiscussion@lemmy.world or !uspolitics@lemmy.world
7) No Hit-and-Run questions.
Please don't delete your post for no apparent reason. If you plan on deleting a question later, say so in the post, or if you feel that you have a good reason to remove it, message a mod beforehand. It's not fair to the ones who took their time to answer, and it's not in the spirit of the community.
Reminder: The terms of service apply here too.

MODERATORS
Right here on Lemmy, someone argued with me for weeks that the mathematical conventions on order of operations can be proven, and that all calculators obey them. You can find calculator manuals with explicit examples that don't obey the conventions, and as a one time mathematician, his attempts at proofs are pathetic. Anyone who persists with him no matter how polite, will be faced with rudeness and condescension.
I found the guy on Mastodon where he peddles the full suite of common mathematical wrongness (he thinks 0.999... ≠ 1) and recently he tried to do an inductive proof in an "educational" thread and got completely schooled by someone else. He was unable to understand that he was wrong.
He claims to be a maths teacher, but his ability ran out at school and he's to arrogant to realise.
Were you arguing with Terrence Howard?
Lol, he's not quite that loopy!
Mathematics will always fascinate me. I am too wise to argue with experts on it. I am not that naive. I love the YouTube channel Numberphile. It really kept my attention better than "college math" lol.
Numberphile has some great stuff :)
Being cursed with a memory good enough to recall some of my math teachers, I'm absolutely willing to believe that someone as comically incompetent as you describe could be a math teacher.
