I'm working on my Math PhD at Brown University. I've finished my second year, and now I pursue my interests in analytic number theory. In particular, I study automorphic forms under Dr. Jeff Hoffstein.

I happen to loosely update a math blog at davidlowryduda.com. I put a lot of MSE things on there too, though a lot of the material caters to whatever class I'm teaching at the time (this fall, calc I).

@BaronVT: Yes, you're right. I feel silly now.

comment Method for Counting the Divisors of a number
Usually when people want to count divisors, they just count the positive ones. If you want to also count the negative ones, then multiple the number of positive divisors by $2$.

You have written down no limits.

Stop defacing this question. I'm removing unrelated comments.

comment homomorphism and resideu classes
I recommend that you choose some explicit numbers and write them down. See if that gets you started. Perhaps $15$ and $5$, for instance.
