mathacademy has a course on linear algebra. currently working my way back up from nothign to get to it. easily the best resource for learning math on the internet.

I do love Math Academy (I signed up 9 months ago in the hopes of replacing my NYT Crossword habit with something more productive, and 9 months later I'm gearing up for multivariable calc, which is neat given that except for linear algebra, which I self-studied out of necessity for cryptography work, all my math education stopped in sophomore year of high school).

It has a very different purpose than a post like this though! Also: there's probably more effort at exposition in this blog post than in all of Math Academy's coverage (that's not a dunk on Math Academy).

haha definitely agree. a lot of these blog posts are great if you want to read about math. mathacademy is pretty much all the exposition chopped out and you spend 90% of your time doing math. I can see how some wouldn't like it but I think the problem solving aspect makes it was more useful for bruteforcing your way towards building intuition

		I like comparing it to Lingua Latina Familia Romana, a book that teaches Latin basically without any English; it opens in Latin and just keeps going that way and somehow you're able to follow along. Both are kind of trippy experiences.
