Each number shown on the card can only be used once and you must get 24 as fast as you can.

The 24 game was invented by Robert Sun, who is from Shanghai and earned his degree in Electronic Engineering in the United States. Sun created this game, in 1988, with the intention of getting students to explore the relationships between numbers. He wanted to show how Math can be powerful, attractive and fascinating. This author supports the idea that patterns are the essence of Math, and emphasizes that it is important to discover different ways to relate numbers.
