Joshua Burch – Elementary Arithmetic
Using a well known mathematical principle Josh Burch believes that he has come upon one of the simplest mathematical forces in magic.
A calculator is used as the magician instructs the participant to make some truly random calculations. In the end they will be forced to end up with one of 3 numbers, the magician makes it look like they predicted the decimal from the beginning.
This mathematical trick takes the difficult to memorize formulas of the past and replaces them with one simple to remember principle.
