sorry if this has been brought up before.
It's been some years since I was in school, and even then I learned matrices one year by rote, without knowing or understanding what they did or they applications.
I'd like to share this playist (Essence of linear algebra by 3Blue1Brown):
It's not about learning linear algebra per se, but it explains visually, with animations and the like what the different processes do and provides intuitions for what its going on.
Hopefully if anyone is struggling with linear algebra like me it will give them some insights.
