    Abstract: A mathematical card game and a method of play are provided. The cards consist of a suit of numeric cards, a wild card and a set of non-numeric cards. The numeric cards and wild card are mixed well and divided evenly among players. Each player places two cards face up in the center. The players use common mathematical operations to make mathematical relationships of the value of the four cards that equals a number determined prior to the game. The first player who correctly explains the relationship of the cards using the non-numeric card pile collects the entire four cards. The wild card can be any numbers from one to thirteen. When no successful match occurs, each player takes their two cards back. At the end of the game the player who has most cards wins.
