The title says it all: I'm confused as to the difference between mathoverflow.net and math.stackexchange.com. Can anyone elaborate?

My its descriptions math.sx is a "Q&A for people studying math at any level and professionals in related fields" and MathOverflow is a "Q&A for professional mathematicians". That's not a big help... :-)


Math Overflow is for research-level math, so if you're a graduate student in Math or a professor, this is probably the correct site for you.

Math.SE is for Math at all levels, so any question you might ask on MO, you could also ask on Math.SE.

    Shows how much I pay attention; I thought they were the same site! – Andrew Barber Oct 15 '13 at 12:49
  • If one completely overlaps the other, shouldn't something about that be changed? – user236578 May 21 '14 at 12:12
  • The reason for the overlap is b/c Math Overflow has been around for longer. – Gabriel Fair Nov 24 '17 at 21:45
