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 sign is predominantly used in algebra to denote the binary operation of addition, and only rarely to emphasize the positivity of an expression. 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.
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 +.
The minus–plus sign, ∓, is generally used in conjunction with the ± sign, in such expressions as x ± y ∓ z, which can be interpreted as meaning x + y − z or x − y + z (but not x + y + z or x − y − z ). The ∓ always has the opposite sign to ± .
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 ...
Typographical symbols and punctuation marks are marks and symbols used in typography with a variety of purposes such as to help with legibility and accessibility, or to identify special cases. This list gives those most commonly encountered with Latin script. E a far more comprehensive list of symbols and signs, see List of Unicode characters. For other languages and symbol sets (especially in ...
The multiplication sign ( × ), also known as the times sign or the dimension sign, is a mathematical symbol used to denote the operation of multiplication, which results in a product. [1]
The null sign (∅) is often used in mathematics for denoting the empty set (however, the variant φ is more commonly used). The same letter in linguistics represents zero, the lack of an element. It is commonly used in phonology, morphology, and syntax .
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.
