Description
Your audience puts the number sticks on the table themselves. They decide whether they want to use 2, 3 or 4 sticks. Before they have entered the first digit on the calculator, you have told them the result. As shown in the image, 5792+7377+9684+6829 = 29682. And you can say that result in less than a second.
The principle is brilliant and you don’t even need to be good at math. It’s like a good friend of mine said: It doesn’t matter if you can do math, as long as you can figure it out.
