ition by Arnold J. Insel, Lawrence E. Spence, and Stephen H. Friedberg. I feel like the textbook lacks explanation considering this is my first exposure to linear algebra. At this point in the semester, I feel like I have a good idea of the concepts and how to represent them (e.g. I understand and can visualize what is happening in space) because I've spent a lot of time learning from alternative resources. What I am having trouble with now is when I go back to the book, I can follow the examples to an extent, but there are computations that aren't explained and I don't know where they are coming from. Moreover, and more importantly, I don't know how to approach the assignment questions at all.
