What to post in r/learnmath
What fits the room, and what gets removed.
Works well
- Ask a genuine math question you actually have, no matter how basic, because the description promises every question gets an answer.
- Share a math-learning resource you really used and explain in your own words what it helped you understand.
- Describe a concept that finally clicked for you and ask others how they think about it.
- Answer other people's math questions patiently when you genuinely know the answer.
- Ask for advice on the best path to learn a specific math topic before you build something that needs it.
Avoid
- Posting a bare link or pitch with no math learning purpose, because the moderator one-liner asks for helpful and relevant content.
- Dropping an ad in a community whose description promises patient answers to basic questions.
- Asking a vague question that gives helpers nothing to work with.
- Being rude or dismissive to people who answer you, since the survival tips stress politeness.
- Treating the absence of rules as permission to spam, because no rules still means the community decides what feels relevant.

What r/learnmath Is For
This is a place for people who are learning math. The public description says to post all of your math-learning resources here, and it makes a promise that questions, no matter how basic, will be answered to the best ability of the online subscribers. So the room is full of learners asking questions at every level, plus people sharing resources that helped them. The moderator one-liner sums up the spirit simply: keep your math questions and resources helpful and relevant. That is the whole job. If your post helps someone learn math, it belongs here.
What To Post
A good post here is a clear math question or a resource that genuinely helps someone learn. If you are a founder, the honest move is to show up as a learner first. Ask the math question you actually have, even if it feels basic, because the description promises that questions no matter how basic will be answered. If you built something that helped you learn math, you can describe it in plain words and what it did for you, and let people ask about it if they want. Answer other people's questions when you can, because the moderator one-liner asks everyone to keep posts helpful and relevant, and being useful is the whole currency here. Write like a person, not a landing page.
What To Avoid
There are no published rules here, so I cannot point to a rule that bans anything, and I will not invent one. What I can point to is the moderator one-liner, which says to keep your math questions and resources helpful and relevant. That means a post with no real math learning purpose, like a bare link dump or a pitch that never touches math, does not fit what this space is for. A vague or confusing question also wastes the goodwill of people trying to help. And since the survival tips lean on politeness, being rude to someone who tried to answer you is the fastest way to wear out your welcome.
A note from Anthony
This is one of the friendliest setups I have seen in these guides, because the description itself promises that no question is too basic to be answered. There are no published rules at all, which is rare, and it puts the burden on you to read the room instead of a rulebook. My honest read is that a community this open earns that openness through people who genuinely want to help, so the only safe way in is to be one of them. If your product only makes sense here as an ad, it does not make sense here.

Common questions about r/learnmath
Can I promote my math product here?
There are no published rules on promotion, so nothing in the rules bans it, but the moderator one-liner says to keep posts helpful and relevant, so any promotion should be wrapped in genuine help for someone learning math.
Are links allowed?
The rules page shows nothing about links, so there is no published ban, but a link only makes sense if it is a math-learning resource that fits the description of this community.
Is my question too basic to post?
No, the description says questions, no matter how basic, will be answered to the best ability of the online subscribers.
Can I use AI-generated content in my posts?
Nothing in the published rules or the moderator one-liner addresses AI content, so there is no stated policy either way, and the safest path is to write in your own voice about your own learning.
What happens if I break a rule?
There are no published rules and no stated enforcement policy, so I cannot tell you what moderators will do, and I will not guess beyond what the evidence says.
