THE PUBLIC MATH ARCHIVE
The public Dogmathic math archive, with written notes and free downloads.
The public Videos and Shorts listings were checked through their final pages.
Titles, video runtimes, and channel ownership were checked against public Dogmathic pages on November 4, 2026. PDF-note links lead to the original Dogmathic download pages on Fourthwall. Downloads may require its checkout flow.
Subjects, subtopics, difficulty levels, and search keywords were assigned for browsing; they are not official course levels. Every subject has subtopic filters, which work together with search, format, and difficulty. Search checks titles, topic keywords, and alternate names, including “Am I a Potato?” It also handles word order and accents. Video thumbnails are the original public YouTube images.
