The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics. Additionally, the subsequent columns contains an informal explanation, a short example, the Unicode location, the name for use in HTML documents, [1] and the LaTeX symbol.
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. As formulas are entirely constituted with symbols of various types, many symbols are needed for ...

Examples are: nasal palatal approximant [j̃] nasal labialized velar approximant [w̃] voiceless nasal glottal approximant [h̃] In Portuguese, the nasal glides [j̃] and [w̃] historically became /ɲ/ and /m/ in some words. In Edo, the nasalized allophones of the approximants /j/ and /w/ are nasal occlusives, [ɲ] and [ŋʷ].
