Tennis is a sport in which the mathematics involves an unusual scoring system together with other applications pertinent to the draw for different types of tournaments and the relative ratios of points won and lost. The name of the sport is thought to have originated from the French word "tenez", which translates roughly as "to receive (the ball)". However, there is an alternative possibility connected with the Egyptian city, Tennis, which was noted in the Middle Ages for its linen from which early tennis balls were made. This article describes mathematical exercises involving both tennis competitions and scoring.
