This is a list of symbols found within all branches of mathematics to express a formula or to replace a constant . When reading the list, it is important to recognize that a mathematical concept is independent of the symbol chosen to represent it. For many of the symbols below, the symbol is usually synonymous with the corresponding concept (ultimately an arbitrary choice made as a result of the cumulative history of mathematics), but in some situations a different convention may be used.

Nearly all the abbreviations below have been adopted by Modern English . However, with some exceptions (for examples, versus, modus operandi), most of the Latin referent words and phrases are still foreign and unknown to English. In a few cases, English referents have replaced the original Latin ones (e.g., "rest in peace" for R.I.P. and "post script" for P.S.) Latin was once the universal academic language in Europe. From the 18th century authors started using their mother tongues to write books, papers or proceedings. http://en.wikipedia.org/wiki/List_of_Latin_abbreviations
