Our Process

Every formula is derived, not asserted. If a result is stated, the working that produces it is on the page.

Every diagram is generated from the real numbers it describes, so the picture and the maths always agree.

Guides are corrected and updated when an error is found — including ones already published.

Written for people who never did a maths degree. School algebra is the only assumed prerequisite.

Founder & Editor

I write every guide on this site. The goal is the explanation I wanted when I was learning this material myself: the actual mathematics, worked through in full, without the notation standing in for understanding. Found a mistake? Tell me — corrections get made and noted.
