For example: "All humans are mortal, and Socrates is a human. ∴ Socrates is mortal." ∵ Abbreviation of "because" or "since". Placed between two assertions, it means that the first one is implied by the second one. For example: "11 is prime ∵ it has no positive integer factors other than itself and one." ∋ 1. Abbreviation of "such that".
For example, "almost all prime numbers are odd". There is a more complicated meaning for integers as well, discussed in the main article. Finally, this term is sometimes used synonymously with generic, below. arbitrarily large Notions which arise mostly in the context of limits, referring to the recurrence of a phenomenon as the limit is approached
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 —
My summary is: A hyphen is an optional tool to be used when it fulfils a purpose. If that purpose does not exist, then do not use a hyphen. For example, an author can use a hyphen for the purpose of linking number word pairs when the reader might reasonably have more than one choice of interpretation of the text. For example:
Examples: 1:a klass "first grade (in elementary school)", 3:e utgåvan "third edition", but 6 november. Furthermore, suffixes can be left out if the number obviously is an ordinal number, example: 3 utg. "3rd ed".

This essay explains use of the non-breaking hyphen character ‑, U+2011, coded by ‑ or ‑. Once displayed in a page, the non-breaking hyphen can be copied into words, or abbreviations, so they will not wrap at the hyphen character, such as an interstate highway symbol, "I‑94", which would always wrap to the next line as a whole word.
Mathematical notation is widely used in mathematics, science, and engineering for representing complex concepts and properties in a concise, unambiguous, and accurate way. For example, the physicist Albert Einstein's formula = is the quantitative representation in mathematical notation of mass–energy equivalence. [1]
