Figures are chapter counts.

What's inside

Chapters.

Each one is a self-contained textbook section — definitions, motivation and full derivations, so a result is shown rather than asserted.

Practice.

Short auto-graded questions that confirm a chapter's methods work. Every one carries a complete worked solution.

Problem sets.

Printable sheets worked on paper — proofs, sketches and find-the-error problems that auto-grading cannot ask — with full solutions on a separate page.
