The intention of these pages or tools is to aid in the understanding of mathematics. I am a teacher first, and a computer geek second and that is intentional. What this means is that I have built a useful set of pages that help students (as well as myself) go through many of the steps it takes to find a linear regression line or the row operations in a Gauss-Jordon method.
