 Jan29 awarded Good Question Jan28 awarded Favorite Question Nov3 comment Explanation of method for showing that 0 / 0 is undefined I see that this comment was made four years ago, but I said that I would revise or defend my position on the basis of comments. So, could a simple example be provided of one particular part of mathematics that would be broken as a result? Oct31 awarded Good Question Oct20 comment Why must the base of a logarithm be a positive real number not equal to 1? This doesn't answer the question about why the base of the logarithm cannot be negative. Oct16 awarded Notable Question Oct10 accepted If all vectors in a set are perpendicular to a given vector, is the set linearly dependent? Oct8 comment If all vectors in a set are perpendicular to a given vector, is the set linearly dependent? Hmmm, I should have specified that I was considering three vectors over three dimensions, or two vectors over two dimensions. Not sure whether I should edit the question or pose a new one. (Although my reason for suspecting it to be true is now looking dubious, so perhaps I should just ask for a counterexample to the conjecture.)

Jul20 awarded Yearling Jul2 awarded Curious May19 awarded Famous Question Apr29 awarded Popular Question Apr9 awarded Notable Question Mar30 awarded Notable Question Jan8 comment What's the explanation for why n^2+1 is never divisible by 3? I like the first three paragraphs, although I'd start the first with "For any integer $n$,". Why not conclude with "Thus, for any value of $n$, either $n^2$ or $n^2 - 1$ is a multiple of three, so the next multiple of three above $n^2$ is either $n^2+2$ or $n^2+3$."? Dec12 comment Are there any interesting semigroups that aren't monoids? Although this answers the question in the title, it seems to ignore the second paragraph where I try to tighten what is meant by the question.
