    en.wikipedia.org/wiki/Twenty-One_Card_Trick

    After three steps, the middle card (*) is the one in all chosen piles. The Twenty-One Card Trick, also known as the 11th card trick or three column trick, is a simple self-working card trick that uses basic mathematics to reveal the user's selected card. The game uses a selection of 21 cards out of a standard deck. These are shuffled and the ...

  5. Operation (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Operation_(mathematics)

    The most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse. An operation of arity zero, or nullary operation, is a constant.

  6. Peano axioms - Wikipedia

    en.wikipedia.org/wiki/Peano_axioms

    In second-order logic, it is possible to define the addition and multiplication operations from the successor operation, but this cannot be done in the more restrictive setting of first-order logic. Therefore, the addition and multiplication operations are directly included in the signature of Peano arithmetic, and axioms are included that ...

    During his free time, he studied magic, working toward his goal of a career in professional magic. In 1960, Schneider developed the Matrix magic trick, where four cards are placed over four coins, and the coins then invisibly move between cards. Matrix is a modernized version of Yank Hoe's "Sympathetic Coins."

  9. Lunar arithmetic - Wikipedia

    en.wikipedia.org/wiki/Lunar_arithmetic

    It is not known whether there are any magic squares of squares of order 3 with the usual addition and multiplication of integers. However, it has been observed that, if we consider the lunar arithmetic operations, there are an infinite amount of magic squares of squares of order 3. Here is an example: [2]
