Plus–minus sign
The plus–minus sign, ±, is a mathematical symbol with multiple meanings. In mathematics, it generally indicates a choice of exactly two possible values, one of which is obtained through addition and the other through subtraction. In experimental sciences, the sign commonly indicates the confidence interval or uncertainty bounding a range of possible errors in a measurement, often the standard deviation or standard error. The sign may also represent an inclusive range of values that a reading might have. In medicine, it means "with or without". In engineering, the sign indicates the tolerance, which is the range of values that are considered to be acceptable, safe, or which comply with some standard or with a contract. In botany, it is used in morphological descriptions to notate "more or less". In chemistry, the sign is used to indicate a racemic mixture. In chess, the sign indicates a clear advantage for the white player; the complementary minus-or-plus sign, ∓, indicates the same advantage for the black player. In electronics, this sign may indicate a dual voltage power supply, such as ±5 volts means +5 volts and -5 volts, when used with audio circuits and operational amplifiers. In linguistics, it may indicate a distinctive feature, such as [±voiced].
