alt Hacker News> here'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.
