In these tutorials, we'll cover a lot of ground. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. Without it, it's impossible to move forward. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you.
It's also seen as a "gatekeeper" subject.
As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. Please.Practice this lesson yourself on right now:Īlgebra I on Khan Academy: Algebra is the language through which we describe patterns. Therefore I beg of you Khan Academy, please, please add some practice exercises to linear algebra and maybe check out some of the comments on the more frustrating videos. Moreover, the videos go so fast from concept to concept that I'm having a very difficult time solidifying any of the information given, not to mention there is a serious lack of content over there.Īnother reason why I'm writing this is because if you look at all the content on this site and its quality, linear algebra just doesn't hold up very well compared to, say, statistics or calculus. My issue is that there simply aren't any practice exercises on linear algebra. I've attempted to watch the videos on this site, and even though they are more advanced than most stuff around here, I still grasp the concepts roughly. Now I'm doing linear algebra and I'm struggling hard. Just last year I was struggling with calculus before a big exam that might have seen me out of university early, but I watched these videos on Khan Academy and did the exercises and I passed (after maybe a week of thorough practice). I've been on Khan Academy for over 3 years now, and this site has saved my ass more than once.
