The math secret behind the Mystery the Traveling Numbers took me by surprise... It's an amazing addition to the original routine. The thing I like about it most is all the math is done at home. There is no math at all in the actual performance.

You also get a little bonus with "The Numbers on Arm" routine. Dan teaches his delayed-read center-tear, and his justification for doing it is fantastic. The reaction Dan gets from the crowd is a beautiful thing to watch.
