U+2213 ∓ MINUS-OR-PLUS SIGN (∓, ∓, ∓) 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 .
The plus sign (+) and the minus sign (−) are mathematical symbols used to denote positive and negative functions, respectively. In addition, + represents the operation of addition, which results in a sum, while − represents subtraction, resulting in a difference.
In common numeral notation (used in arithmetic and elsewhere), the sign of a number is often made explicit by placing a plus or a minus sign before the number. For example, +3 denotes "positive three", and −3 denotes "negative three" (algebraically: the additive inverse of 3 ).
Sign convention. In physics, a sign convention is a choice of the physical significance of signs (plus or minus) for a set of quantities, in a case where the choice of sign is arbitrary.
1. Denotes either a plus sign or a minus sign. 2. Denotes the range of values that a measured quantity may have; for example, 10 ± 2 denotes an unknown value that lies between 8 and 12. ∓ ( minus-plus sign) Used paired with ±, denotes the opposite sign; that is, + if ± is –, and – if ± is +.
Plus–minus, ±, +/−, or variants may refer to: Plus–minus sign (±), a mathematical symbol which can mean either plus (+) or minus (−), or can indicate the uncertainty of a measurement or statistic; Plus–minus (sports), a sports statistic used to measure a player's impact on the game

6÷2(1+2) is interpreted as 6÷(2×(1+2)) by a fx-82MS (upper), and (6÷2)×(1+2) by a TI-83 Plus calculator (lower), respectively. This ambiguity has been the subject of Internet memes such as "8 ÷ 2(2 + 2)", for which there are two conflicting interpretations: 8 ÷ [2 · (2 + 2)] = 1 and (8 ÷ 2) · (2 + 2) = 16.

The plus–minus sign (±) is a mathematical symbol which can mean either plus (+) or minus (−), or can indicate the uncertainty of a measurement or statistic. Plus–minus, ±, +/−, or variants may also refer to: Plus–minus (sports), a sports statistic used to measure a player's impact on the game.
