If I have a maths question, on which site should I ask: MathOverflow or Mathematics.SE?

    As was stated on the previous MathOverflow FAQ: "MathOverflow's primary goal is for users to ask and answer research level math questions, the sorts of questions you come across when you're writing or reading articles or graduate level books.". I'm sure that in the upcoming days/weeks all the information will be filled out once again.

  • @Oded I am only able to find this: MathOverflow is a question and answer site for mathematicians. It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about research level mathematics.

    @Oded Wow, that took way too many reads to find that. Not at all obvious to find the "research level mathematics" within that (standard?) About page. I glanced over it a couple of times.

    @Oded Oh yes. After reading multiple times, I was unable to find that. :)

    If you have to ask, math.SE Jun 25, 2013 at 22:27

    Well after reading, it's clear that those 2 sites shouldn't be merged. But these post should be merged with this meta.math.stackexchange.com/questions/41/… or viceversa :)

    While this question is older, I feel like the answer to What is the intended difference between MathOverflow and Mathematics? is better and has more detail, and the general policy for duplicate closures is that the one with the better answers should be the canonical. Jan 8, 2021 at 12:53
  • @Sonic What decides "better"? Here, question and answer both have more upvotes. Also, that question survived only because people failed to close it.

    @user178465 See our FAQ on duplicate closures, section Which question is the duplicate?, for the relevant policy. The answer to the other question is much more substantive and detailed, containing quotes from the relevant help centers, and links to related questions discussing more context. The answer here simply tersely states which is which. Jan 9, 2021 at 8:03

It depends on the question.

MathOverflow is for research level questions.

Mathematics.SE is for any level.
