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? -- underground experts united https://dataswamp.org/~incal
