Please watch and work along with the following screencasts (from Khan Academy, which has an extensive list of videos for linear algebra and other subjects) before class on Tuesday, March 8. Note that if you are familiar with adding, subtracting, and multiplying matrices already from other classes, you can skip a lot of what's in the videos here. Please refer to a list of competencies that will be given to you to know whether or not you will need a full review.
