Subreddit rules check

Can you promote here?
Promotion is allowed only with moderator permission (or inside designated threads). A short, honest modmail before posting costs two minutes and functions as a safe-conduct pass; skipping it is the most common avoidable removal.
Links
No explicit link policy. Default to no URL: link-plus-young-account is one of the most common automated removal patterns on Reddit.
What this community rewards
Dominant post formats: question, discussion, guide
Headline: a concise, math-focused title that states the problem or result. Body: clear, precise, formal math writing (use LaTeX or plain symbols), typically 1–5 paragraphs with key steps or definitions. Write as a sober question or exposition (first person for questions). Upvotes go to well-posed problems, correct proofs, and clear explanations; low-effort/homework dumps are removed.
Arriving in the local format matters: cross-posting the same text everywhere reads as tourist instantly. The wider method is in the Reddit playbook.
Classified mechanically from the community's published rules and recent top posts, last checked October 2026. Rules change and moderators have the final say: verify at r/math's rules page before posting anything that matters.
Thread Otter checks this before every send
These profiles power the product: promo-banned communities never receive a promotional draft, drafts arrive in the local format, and a fact-check gate plus human pacing protect the account doing the talking.
