Mathematical notation is a system of symbolic representations of mathematical objects and ideas. Mathematical notations are used in mathematics, the physical sciences, engineering, and economics. Mathematical notations include relatively simple symbolic representations, such as the numbers 0, 1 and 2, function symbols sin and +; conceptual symbols, such as lim, ''dy/dx'', equations and variables; and complex diagrammatic notations such as Penrose graphical notation and Coxeter–Dynkin diagrams. ==Definition== A mathematical notation is a writing system used for recording concepts in mathematics. *The notation uses symbols or symbolic expressions which are intended to have a precise semantic meaning. *In the history of mathematics, these symbols have denoted numbers, shapes, patterns, and change. The notation can also include symbols for parts of the conventional discourse between mathematicians, when viewing mathematics as a language. The media used for writing are recounted below, but common materials currently include paper and pencil, board and chalk (or dry-erase marker), and electronic media. Systematic adherence to mathematical concepts is a fundamental concept of mathematical notation.
