Very important: learning math is about doing problems. That is how you get better. While the complete answers to all questions are available to you, it is crucial that before consulting an answer, you must give the question a good try on your own. If you read the question and just immediately read the answer, then you will not learn.Â
Much of this material is also covered in the appendix of the Linear Algebra textbook, although it is covered in more depth here.Â
