The World's Easiest Mentalism Trick (Peter Turner)

Peter Turner presents a tutorial for a remarkably simple and effective mentalism trick called 'Numerator,' which utilizes a standard smartphone calculator. The trick allows you to seemingly predict the final digit sum of calculations performed by multiple participants. It's designed to be accessible to anyone, completely self-working, and requires no pre-show or sleight of hand. The method relies on a mathematical principle – essentially a modulo 9 operation – where random calculations on a calculator consistently lead to the same final digit for everyone. Turner provides performance tips, including maintaining a straight face, adapting to different group sizes, and even incorporating a playful 'wrong number' to enhance the illusion. He enthusiastically describes it as the 'Mac Daddy' of calculator-based mentalism, emphasizing its repeatability and ease of use, making it a valuable addition to any mentalist's act.
