The plus sign (+) is a binary operator that indicates addition, as in 2 + 3 = 5. It can also serve as a unary operator that leaves its operand unchanged ( + x means the same as x ). This notation may be used when it is desired to emphasize the positiveness of a number, especially in contrast with the negative numbers ( +5 versus −5 ).
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 ±.
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.
The plus sign + (itself based on an et-ligature) is often informally used in place of an ampersand, sometimes with an added loop and resembling ɬ. [ citation needed ] Other times it is a single stroke with a diagonal line connecting the bottom to the left side.
The German layout differs from the English (US and UK) layouts in four major ways: The positions of the "Z" and "Y" keys are switched. In English, the letter "y" is very common and the letter "z" is relatively rare, whereas in German the letter "z" is very common and the letter "y" is very uncommon. [1]
The only variant that exists is an alternative plus sign, which is a plus sign which looks like an inverted capital T. Unicode has this symbol at position U+FB29 "Hebrew letter alternative plus sign" (﬩).
Most keyboard shortcuts require the user to press a single key or a sequence of keys one after the other. Other keyboard shortcuts require pressing and holding several keys simultaneously (indicated in the tables below by the + sign).
On some keyboards, the c-cedilla key (Ç) is located one or two lines above, rather than on the right of, the acute accent key (´). In some cases it is placed on the right of the plus sign key (+), while in other keyboards it is situated on the right of the inverted exclamation mark key (¡). [better source needed]
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 standard notation for this class uses the number sign symbol, not the sharp sign from music, but it is pronounced "sharp P". More generally, the number sign may be used to denote the class of counting problems associated with any class of search problems.
