A few years ago he started uploading his lessons to You Tube, he calls it Wootube, and has more than a quarter of a million subscribers and videos viewed more than 14 million times.
He makes math fun by teaching lessons through interesting questions like why is a rainbow curved and why aren't left handers extinct?
