Introduction to Linear Algebra

“Introduction to Linear Algebra” by Gilbert Strang is the book. Recommend getting a used older edition as not much has changed. His course at MIT is legendary, completely available online https://ocw.mit.edu/courses/18-06-linear-algebra-spring-2010... (https://ocw.mit.edu/courses/18-06-linear-algebra-spring-2010/) And there’s so much good linear algebra stuff on YouTube from 3brown1blue. If you can do one thing now, watch this Veritasium video to disprove the myth that you’re a visual learner: https://youtu.be/rhgwIhB58PA.
