What “notation” means
Wiktionary · Wikipedianotation/noʊˈteɪʃən/
- nounThe act, process, method, or an instance of representing by a system or set of marks, signs, figures, or characters.
In linguistics and semiotics, a notation system is a system of graphics or symbols, characters and abbreviated expressions, used in artistic and scientific disciplines to represent technical facts and quantities by convention. Therefore, a notation is a collection of related symbols that are each given an arbitrary meaning, created to facilitate structured communication within a domain knowledge or field of study.
