## Exploding Dots

## Overview

Here is a story that isn’t true:

*When I was a young child I invented a machine (not true) that was nothing more than a series of boxes that could hold dots. And these dots would, upon certain actions, explode. And with this machine, in this non-true story, I realized I could explain true things! In one fell swoop I explained all the mathematics of arithmetic I learnt in grade school (true), all of the polynomial algebra I was to learn in high-school (true), elements of calculus and number theory I was to learn in university (true), and begin to explore unanswered research questions intriguing mathematicians to this day (also true)!*

Let me share this story with you. See how simple and elegant ideas connect to elegant and profound ideas in mathematics as a whole. **See how these ideas will COMPLETELY REVOLUTIONIZE your thinking of school arithmetic and algebra and beyond!**

This course will knock your socks off! (And for something exciting and big on this topic, see The Global Math Project.)
