This is an excellent course. That's where I first learned about the "column picture" of matrix multiplication... and this after 10+ using linear algebra and teaching. Overall LA can be a complicated subject, but Strang does a good job at making it seem like common sense. For more linear algebra goodness, check out the 3Blue1Brown playlist, which provides a lot of the important geometric intuition: https://www.youtube.com/playlist?list=PLZHQObOWTQDPD3MizzM2xVFitgF8hE_ab https://www.youtube.com/playlist?list=PLZHQObOWTQDPD3MizzM2x... Another good book with visuals and manipulatives is http://immersivemath.com/ila/index.html http://immersivemath.com/ila/index.html And this is a short tutorial that I wrote that summarizes some of the main ideas of LA in just four pages: https://minireference.com/static/tutorials/linear_algebra_in_4_pages.pdf https://minireference.com/static/tutorials/linear_algebra_in... You can print this and enjoy with your weekend coffee tomorrow. For bonus points, you can also learn how to do LA using SymPy here https://github.com/minireference/sympytut_notebooks/blob/master/notebooks/Linear-algebra.ipynb https://github.com/minireference/sympytut_notebooks/blob/mas...
