However, numeric entry of Unicode characters is possible in most Unix or Unix-like OSs by pressing and releasing Ctrl + ⇧ Shift + U, and typing the hex number followed by the space bar or enter key. For example, For the registered trademark symbol ®, type Ctrl + ⇧ Shift + U, AE, ↵ Enter. For the no entry sign ⛔, type Ctrl + ⇧ Shift ...
The plus–minus sign or plus-or-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. In statistics and experimental sciences, the sign commonly indicates the confidence interval or ...
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] Their use has been extended to many other meanings, more or less analogous.
± (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 +.

Mathematical operators and symbols are in multiple Unicode blocks. Some of these blocks are dedicated to, or primarily contain, mathematical characters while others are a mix of mathematical and non-mathematical characters. This article covers all Unicode characters with a derived property of "Math". [2] [3]
The four hyphen/dash-like characters used in Wikipedia are: - is a hyphen-minus (ASCII 2D, Unicode 002D), normally used as a hyphen, or in math expressions as a minus sign. – is an en dash (Unicode 2013). This can also be entered from the Special characters: Symbols bar above the text-entry field; it's between the m³ and —.
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).
