> another textbook that is hard and complex To be fair, you were looking at the super-condensed linear algebra tutorial, which is meant to be a condensed pre-exam review for students and not as a standalone tutorial. The actual book starts off much more smoothly and introduces concepts step by step (see http://cnd.mcgill.ca/~ivan/miniref/noBSguide2LA_preview.pdf http://cnd.mcgill.ca/~ivan/miniref/noBSguide2LA_preview.pdf for a preview). The "onboarding" in the math/phys book (No bullshit guide to math and physics) is even smoother. About 1/3 of the text is a review of high school math topics, which helps to establish a solid foundation understanding mechanics and calculus. (see http://minireference.com/static/excerpts/noBSguide_v5_preview.pdf http://minireference.com/static/excerpts/noBSguide_v5_previe... for a PDF preview.) You are absolutely right though, many of the readers who have written to me over the years are adults who used the book to review what they learned at university. The compactness works well for that.
