The greater-than sign is a mathematical symbol that denotes an inequality between two values. The widely adopted form of two equal-length strokes connecting in an acute angle at the right, >, has been found in documents dated as far back as 1631. [1] In mathematical writing, the greater-than sign is typically placed between two values being ...
Glossary of mathematical symbols. A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula.

Aleph-one. ℵ 1 is, by definition, the cardinality of the set of all countable ordinal numbers. This set is denoted by ω 1 (or sometimes Ω). The set ω 1 is itself an ordinal number larger than all countable ones, so it is an uncountable set. Therefore, ℵ 1 is distinct from ℵ 0. The definition of ℵ 1 implies (in ZF, Zermelo–Fraenkel ...
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. For a far more comprehensive list of symbols and signs, see List of Unicode characters.

Guillemet. Guillemets (/ ˈɡɪləmɛt /, [1][2] also UK: / ˈɡiːmeɪ /, [3] US: / ˌɡiː (j) əˈmeɪ, ˌɡɪləˈmɛt /, [4] French: [ɡijəmɛ]) are a pair of punctuation marks in the form of sideways double chevrons, « and », used as quotation marks in a number of languages.

Alt code. On personal computers with numeric keypads that use Microsoft operating systems, such as Windows, many characters that do not have a dedicated key combination on the keyboard may nevertheless be entered using the Alt code (the Alt numpad input method). This is done by pressing and holding the Alt key, then typing a number on the ...
For example, B− ("B minus") is one grade lower than B. In some occasions, this is extended to two plus or minus signs (e.g., A++ being two grades higher than A ). A common trend in branding, particularly with streaming video services, has been the use of the plus sign at the end of brand names, e.g. Google+ , Disney+ , Paramount+ and Apple TV+ .
