Glossary of mathematical symbols. 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 ...
Braille cell, 2 dots wide by 3 dots high. Braille music is a braille code that allows music to be notated using braille cells so music can be read by visually impaired musicians.
