Ever since I learned about math writing in LaTeX, I have really enjoyed it.
Over the summer before my freshman year of college, I spent hours rewriting a few papers I had written in google docs (yes with the horrible math integration) in LaTeX. I am now a 2nd-year undergraduate studying to pursue a pure math degree (I especially enjoy number theory).
In all of my math classes, I write my homework up in LaTeX, even though my classmates write it by hand and finish their HW in half the time it takes me. Still, I really enjoy the way my final product looks. I don't get any extra points for doing this, I just really love proof-writing and especially finalizing it in a way that looks professional.
My question is this: are there any career routes that specifically focus on mathematical writing? Obviously, math researchers write their own papers, but I'm curious if there is something more to math paper writing.
