We have written a trilogy of books called: Rigorous Elementary Mathematics. It is currently in editing stage with a potential release date by the end of 2022! The cumulative number of pages is over 700. The plan is to provide electronic copies for free to those who sign up for our newsletter, and concurrently self-publish paperbacks for those who want a physical copy. The tables of contents are provided below as a sample. To stay up to date on this project, please sign up for our Newsletter.
