In mathematics, the first symbol is mainly used in Anglophone countries to represent the mathematical operation of division and is called an obelus. [3] In editing texts, the second symbol, also called a dagger mark † is used to indicate erroneous or dubious content; [4] [5] or as a reference mark or footnote indicator. [6]
French also uses the indicators d and de for the alternative second ordinal number (masculine 2 d – second; feminine 2 de – seconde). In plural, all these indicators are suffixed with an s: ers (1 ers – premiers), res (1 res – premières), es (2 es – deuxièmes), ds (2 ds – seconds), des (2 des – secondes).
Some scholars used the obelus and various other critical symbols, in conjunction with a second symbol known as the metobelos ("end of obelus"), [15] variously represented as two vertically arranged dots, a γ-like symbol, a mallet-like symbol, or a diagonal slash (with or without one or two dots). They indicated the end of a marked passage.

The asterisk (/ ˈ æ s t ər ɪ s k / *), from Late Latin asteriscus, from Ancient Greek ἀστερίσκος, asteriskos, "little star", [1] [2] is a typographical symbol. It is so called because it resembles a conventional image of a heraldic star.
The names and symbols of SI base units are written in lowercase, except the symbols of those named after a person, which are written with an initial capital letter. For example, the metre has the symbol m, but the kelvin has symbol K, because it is named after Lord Kelvin and the ampere with symbol A is named after André-Marie Ampère.
