Tennis a new point. A game consists of a sequence of points played with the same player serving. A game is won by the first player to have won at least four points in total and at least two points more than the opponent. The running score of each game is described in a manner peculiar to tennis: scores from zero to three points are described as ""love"", ""15"", ""30"", and ""40"", respectively. If at least three points have been scored by each player, making the player's scores equal at 40 apiece, the score is not called out as "40-40", but
Zero to the power of zero Zero to the power of zero Zero to the power of zero, denoted by 0, is a mathematical expression with no agreed-upon value. The most common possibilities are 1 or leaving the expression undefined, with justifications existing for each, depending on context. In algebra, combinatorics, or set theory, the generally agreed upon value is 0 = 1, whereas in mathematical analysis, the expression is generally left undefined. Computer programs also have differing ways of handling this expression. There are many widely used formulas having terms involving natural-number exponents that require 0 to be evaluated to 1. For example, regarding "b"
