 Apr 17 asked What is the determinant of the sum of a diagonal matrix and a matrix of ones? Apr 11 accepted Is there a totally ordered set we can map any other totally ordered set to? Apr 11 comment How to prove that $\lim\limits_{x\to0}\frac{\sin x}x=1$? While this is indeed an interesting approach, integrals haven't been taught at the point where this limit is proved. Thank you for your answer though. Mar 24 awarded Notable Question Mar 23 comment What is the lower bound for an algorithm that reconstructs a permutation? I fixed a couple of typos. I'm sorry if that changes your answer.

Indeed, it's easy to see that this holds if one uses a series, but this question starts on the prerequisite that one does not use a series.

Mar 4 awarded Great Question Mar 3 comment Is there a totally ordered set we can map any other totally ordered set to? I edited the question because I thought that the case $|O|=|\mathbb N|$ might be interesting, too. Thank you for researching this!
