I did Linear Algebra in a period of pitch-black self-sacrifice
way back in 2009-06-10, hm, 11y 10m 25d 0h 0min 0s (4347 days)
ago, and it was so miserable doing that stuff I wrote a pretty
big program in SML to do all the common matrix operations,
including adding multiples of a row and stuff like that.

Now you tell me Emacs could do it all along?
