Self Working Effect
This is an easy to do effect, where you can have a multiple spectators participate at the same time if you would like. They follow easy instructions, and you can reveal their number(s). No sleight of hand, nor any complicated memory work necessary. You will learn and be able to perform this in less than an hour.

Excellent
Thorough explanation, and also followed by interesting jam session where multiple ways of presentation are discussed. Good value!

Strong Mentalism that Plays Big
Having watched the performance in the trailer and then learning how that was done, I at first thought I was going to be a little disappointed – that maybe I had gotten something that wasn’t quite what I thought. But then I watched the full jam session with Turner and three others throwing out so many different uses and presentations of the Numerator principle. That video is full of nuggets of gold that give you tons of ideas to mess around with and a principle that can be used to create some incredible strong and unbelievably fair mentalism that gets multiple people involved and plays great for a big audience. Definitely recommend.
