Linear Algebra Problem Book (1995, Mathematical Association of America) by Paul R. Halmos is a unique and celebrated text. Unlike conventional linear algebra textbooks, it presents the subject almost entirely through a carefully sequenced set of problems, with solutions and commentary provided in the second half. It is especially valued by advanced undergraduates, graduate students, and instructors for building deep conceptual understanding and proof‑writing skills.

If you are willing to share your context (student, instructor, self‑learner, no local library access), I can suggest more tailored legal paths to obtain either the book or an equivalent structured problem‑based resource.
