comment Are cyclic groups always abelian?
Sounds good. And in fact, having this picture is great because it shows that each row (or column) is the previous row (or column) shifted by 1. What's more is that if we associate $e,a,b$ with $g^0, g^1, g^2$, then we can see the "addition table" structure come out.

comment Are cyclic groups always abelian?
This is a valid example, but giving a single example doesn't explain why we'd expect cyclic groups to be abelian in general.

comment Contemporary Mathematical Columns in Magazines
I know these aren't columns, but do resources like TopCoder or Project Euler qualify?

comment How can I calculate the standard deviation knowing an event probability and a number of trials?
Good question! I hope it's okay that I removed the "probability-theory" tag.

comment Largest Part of a Random Weak Composition
That's a cool insight; if you actually use this approximation, what can you say about the error (especially when $n$ is small)?

Fine, I'll drop the word "hypothesis" from my vocabulary.

comment A probability question about a dog
Dan, what would be the "right" hypothesis to consider for this problem (instead of "at any time, a dog has the probability of p to bark")?
