## Overview

### GLOBAL MATH WEEK is here!

It’s a global phenomenon happening now, across the entire globe. The joyous uplifting mathematics of Exploding Dots is being enjoyed by one million – YES! One Million! – students and teachers across the entire globe this very week!

Register and be part of this beautiful phenomenon here

It all begins with 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 mathematical story will knock your socks off!

SCROLL DOWN to see and access the Exploding Dots chapters. Play with them at your leisure. (Warning: When you start one, you won’t want to stop!)
