From the creator who brought you Swap and Sharp Edged comes the best way to read the two digit number that is in the spectator mind.

The spectator is free to think of three numbers, let's say the numbers are 7, 12 and 21. Then all the numbers are added in their phone calculator and become a new random number. Whatever number they have they need to remember it. Then in a simple and short process you can know the number they are thinking of.

IMPORTANT POINTS:

1. The use of a phone calculator is required because it simplifies the addition process. (recommended)

2. Nothing on the phone, spectator use their own phone calculator. You never peeked at any numbers. Yes, really. You can do this trick over the phone if you want to.

3. This is not a force. The spectator is free to choose all the numbers and the results will always be different every time you perform.
