BTW, if one wants to see more problems with worked out answers than their professor and/or textbook provides, there are books you can buy for this. For linear algebra for example you could get Schaum's Outline of Linear Algebra [1] for $13.44 which includes 612 practice problems with step-by-step solutions.
There are such books for most of the major first and second year undergraduate STEM and STEM-adjacent courses.

In many math courses, there is the oficial theoretical book, and the "Schaum" as a side book that has a lot of exercises. So it may be useful.
The serie cover a lot of math topics, with a similar style https://www.amazon.com/dp/B09ZP6Q2NC?binding=paperback&ref=d...
