The plus–minus sign, ±, is a 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 statistics and 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 chess, the sign indicates a clear advantage for the white player; the complementary minus-plus sign, ∓, indicates the same advantage for the black player.
Other meanings occur in other fields, including medicine, engineering, chemistry, electronics, linguistics, and philosophy.
