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.
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).
± (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 +.
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 .

Mathematical notation consists of using symbols for representing operations, unspecified numbers, relations, and any other mathematical objects and assembling them into expressions and formulas. Mathematical notation is widely used in mathematics , science , and engineering for representing complex concepts and properties in a concise ...
U+2248 ≈ ALMOST EQUAL TO. U+2261 ≡ IDENTICAL TO. A well-known equality featuring the equal sign. The equals sign ( British English) or equal sign ( American English ), also known as the equality sign, is the mathematical symbol =, which is used to indicate equality in some well-defined sense. [1]
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 ...
