So, long story short, I'm trying to teach myself some of the basics of linear algebra (if you want to know why, see the last paragraph). I found an awesome video series on Khan Academy that I'm going through to get started. However, there aren't any practice problems on the Khan Academy page.

Where could I find free, simple online problems to practice the stuff I'm learning in the videos? Requirements would be that it is somewhat simpler (I'm in 8th grade), online, and free. I wouldn't mind a textbook if it is, again, online and free. Specifically, right now I just finished a video about vector multiplication and addition.

As for why I'm trying to teach myself the basics of linear algebra in 8th grade, I'm trying to teach myself a bit about quantum computing, and I found a video series that will teach it (including the quantum mechanics behind it) but it requires some knowledge of linear algebra. So.


  • $\begingroup$ google "linear algebra problems and solutions" : google.com/#q=linear+algebra+problems+and+solutions - find a link with problems that suit your level. $\endgroup$ – Ethan Bolker Sep 10 '16 at 14:34
  • $\begingroup$ Paul's Notes are a good textbook resource with some worked examples, but not much in the way of practice problems $\endgroup$ – Omnomnomnom Sep 10 '16 at 19:00
  • $\begingroup$ You might like to take a look at expii.com - they have lessons geared towards high schoolers, and I think they usually have a lot of problems to test yourself with. $\endgroup$ – Shagnik Sep 17 '16 at 20:38
  • $\begingroup$ Schaum's Outline isn't free, but it's probably not very expensive, and has large numbers of exercises, with solutions. $\endgroup$ – Gerry Myerson Sep 20 '16 at 7:11
