A comprehensive math book from basic operations to differential equations.
Covers Algebra, a means of modeling scenarios and manipulating numbers and operations.
Covers Geometry, a field of math focused on shapes, space, and dimensions!
Covers Discrete Math, a branch of mathematics focusing on logic, Boolean Algebra, and more.
Welcome!
This is a math book I am currently writing that covers math from basic operations all the way to differential equations. Based upon my own knowledge, my old school notes, and many things I picked up along the way.
This book was originally began in October of 2019, completed sometime during the COVID-19 pandemic, left to collect digital dust for a few years (to age like fine wine, of course), and finally revived in 2025 when I decided to finally get around to making the document a lot better.
This document began as a Word doc that became around 210 pages (43231 words). Maintaining this was cumbersome as even loading the document took a couple minutes, not to mention the lag and slow-loading images.
Therefore, Markdown has been selected for the revival, so it can be version controlled, cleaned up, and separated nicely. It also has the added benefit of being relatively easily converted to other formats, like HTML, Word docs, etc.
The goal is to have a free, open-source centralized book that can be used as a reference, as teaching material, etc. I believe knowledge should be freely available, and hiding it behind a paywall is ridiculous.
This is licensed under the GNU GPLv3 License. This is meant to be a free book, so just don’t sell it.
Although not on GitHub (yet), I have many other books, including Physics, Chemistry, Astronomy, and plenty of others that will be done “eventually”. Math is just the first one I am beginning with.
