Plus and minus signs. 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]
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. In some contexts, it makes sense to consider a signed zero (such as floating-point representations of real numbers within computers). Depending on local conventions, zero may be ...

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 .
Plus Codes logo. The Open Location Code (OLC) is a geocode based in a system of regular grids for identifying an area anywhere on the Earth. It was developed at Google's Zürich engineering office, and released late October 2014. Location codes created by the OLC system are referred to as "plus codes".
± (plus–minus sign) 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 +.
A variant, LGBTQ, adds the letter Q for those who identify as queer (which can be synonymous with LGBT) or are questioning their sexual or gender identity. Another variation, LGBTQ+, adds a plus sign "represents those who are part of the community, but for whom LGBTQ does not accurately capture or reflect their identity".
In chemistry, a chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs.
This article contains Unicode mathematical symbols. Without proper rendering support, you may see question marks, boxes, or other symbols instead of mathematical symbols. The following table lists many specialized symbols commonly used in modern mathematics, ordered by their introduction date.
Mathematical Operators is a Unicode block containing characters for mathematical, logical, and set notation. Notably absent are the plus sign (+), greater than sign (>) and less than sign (<), due to them already appearing in the Basic Latin Unicode block, and the plus-or-minus sign (±), multiplication sign (×) and obelus (÷), due to them ...
