What this sub rewards
How replies earn upvotes here
- Explain reasoning step by step when the topic involves a process.
- Back specific claims with evidence — research, data, or named sources. Primary sources beat secondary. Wikipedia is a starting point, not a citation.
- Acknowledge limitations, trade-offs, or uncertainty when relevant. Mark what's contested vs settled. Historical interpretation evolves; physics doesn't.
- Offer multiple options or perspectives, not a single prescription. Name 2–3 frameworks for the same question. Single-framework answers get pushback.
What good looks like
Real comments that landed in r/askmath
Two recent highly-upvoted replies. Notice what they have in common — concrete, no preamble, no self-promotion.
"So basically if you changed the the definition of distance (a thing called a norm). Search up taxicab distance for the most intuitive norm (not the Euclidean one)"
"No, the teacher is the idiot. They have the same number of squares, but each square in B is covering more area, thus the whole rectangle B is bigger."
Your pre-reply checklist
Before you hit Reply — four quick checks
Does my comment add something specific, not just an opinion?
A useful reply names a number, a method, a personal experience, or a concrete example. If you could replace your draft with "I agree" and lose nothing, rewrite.
Have I read the top 3 comments already on this thread?
If the highest-upvoted reply already says what you were about to say, your comment will sink. Add what's missing — counterexamples, edge cases, the next step — not what's there.
Would my reply still work if my username was removed?
If it only makes sense because it promotes you, your product, or your platform, this sub will spot it. Frame the value as "this solved it for me," not "check out my…"
Did I skim the sidebar rules one more time?
Every sub has at least one rule that surprises outsiders — peer-review only, no images, no specific tags, no off-topic. Five seconds in the sidebar can save you a removal.
