Summary of MENTOR problem-solving session
March 25, 2016

About presentations, can keep in mind the short note How to Give a Good Colloquium. It was published in 1999, so a few suggestions (e.g.,"Do not use slides"), while good, might be hard to follow.

Discussed LaTeX, including Beamer (a LaTeX style to make presentations, similar to Powerpoint).

Why LaTeX/Beamer:
Because it makes writing mathematics much easier than with other tools.
It also takes care automatically of the numbering of sections, theorems, equations, etc., making it very convenient for writing long documents.
