The plus–minus sign or plus-or-minus sign (±) and the complementary minus-or-plus sign (∓) are symbols with broadly similar multiple meanings. In mathematics, the ± sign generally indicates a choice of exactly two possible values, one of which is obtained through addition and the other through subtraction.
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; Plus–minus method, a geophysical method to interpret seismic refraction profiles
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 . [ 1 ]
A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
The plus and minus symbols are used to show the sign of a number. In mathematics, the sign of a real number is its property of being either positive, negative, or 0.Depending on local conventions, zero may be considered as having its own unique sign, having no sign, or having both positive and negative sign.
The temperature was minus-13 with a wind-chill of minus-36. ... another in ’66, plus the first non-Super Bowl Super Bowl in ‘67, and another NFL title in the Ice Bowl at the end of the ’67 ...
The role of the Blue hat is adopted by one person only at any time (like the meeting chairman) and determines the sequence of thinking under the other hats. In some ways the Six Hats are a reincarnation of earlier thinking tools devised by de Bono. The PMI (Plus Minus Interesting) tool from CoRT Thinking is similar: P = Yellow hat and M = Black ...
Plus-or-minus can be used as INCLUSIVE disjunction or EXCLUSIVE disjunction. The article currently highlights INCLUSIVE disjunction, and only hints at EXCLUSIVE disjunction, in its discussion of the Taylor series for the sine function, but then points out that a more rigorous presentation would eliminate the need for the plus-or-minus symbol.
