What is the quickest way to learn Linear Algebra?

well yeah, if you're attending a seminar on algorithmic problems of group theory complexity applied to crypto, you already know some group theory, some algorithms, some ring theory and basic number theory, and I assume you already know other pieces of the basic math curriculum like analysis and some probability since you're doing a lot of probability in ML. OP presumably knows noting but linear algebra after he learns that book

what didn't you like about axler's book? i thought it was pretty good

so which should i pick up? i already started with axler now im confused. yes i am starting with 0 LA

you're good with axler
"Advanced linear algebra" is literally advanced: you need tons of more stuff before that, including a full book in linear algebra and some abstract algebra

OK thanks. I'll stick with Axler. I don't know abstract algebra yet, but will pick that up a bit later. Really been wanting to get my teeth in LA

Watch the linear algebra series from 3blue1brown on Youtube.
