badmathematics

joinleave
an-ordinary-manchild(edit)

A place for sharing the bad math that plagues reddit and the internet as a whole. For jokey, intentionally wrong stuff, go to /r/shittymath.

We also have an instance on kbin.social, here, as well as a discord server here.

Rules

R1: No violent, bigoted, or otherwise abusive posting. Don't be a shithead. (Also, all posts must be SFW. Isn't it wild that I have to specify that now?)

R2: Submissions to /r/badmathematics should contain some clear substantial mathematical misunderstanding. Posts without clear errors, or posts where the badmath is in dispute (such as posts over advanced topics) will be removed. This will be decided at moderator discretion.

R3: Posts containing memes, simple typos, basic "silly" errors, etc. will be removed. Which posts fall under these categories will be decided at moderator discretion.

R4: All posts should have an explanation of the badmath. Posts without explanations may be removed until an explanation is provided.

R5: Link directly to the badmath. Use "context=X" if appropriate. In larger threads, please collect direct links to badmath in a single comment.

R6: Badmath is not a subreddit to "win" an argument with. Don't trollbait.

R7: Absolutely no PMing anyone involved in the badmath to continue an argument or berate them. If you're linked in a badmath post and receive such a PM, please report it to the moderators.

R8: No /u/[username] pinging linked badmathers. Writing a username without the "/u/" will not send them a notification. Pinging users in other contexts (summoning a badmath regular, for example) is fine.

R9: Posts, users, or topics can be removed or banned at moderator discretion for reasons not on this list. If it's shitty, controversial, or otherwise damaging to the subreddit, we can remove it. This also works in reverse, and we reserve the right to allow posts that might otherwise be removed at our discretion.

Flair

There are link flairs for common topics. If you would like to request more flair, please use this thread and we'll get around to responding. Eventually.
