About
Math Without Borders is a set of self-paced video math courses produced by physics and math teacher David Chandler. Each course follows a standard textbook, most commonly Paul Foerster's Algebra, Trigonometry, and Precalculus titles, plus Harold Jacobs' Geometry. Chandler works every problem on camera with pencil and voiceover, explaining reasoning step by step. Families purchase the textbook separately and pair it with the download or streaming video license. The program is often chosen by parents who want rigorous textbook content delivered through clear, no-frills instruction.
