Mathematical notation is a field of mathematics. In mathematics and other exact sciences like physics or computer science, problems often need to be presented in some way. In such representations, different symbols have different meanings:

  • There are numbers, like 1 and 2, or variables that stand for such numbers (like x and y)
  • There are functions that act on numbers and variables. Such function take a predetermined number of elements, and do something with them. An example is +, which adds two numbers
  • There are concepts of advanced mathematics such as limits and derivatives

Some mathematical notations use diagrams, or small drawings to show the underlying concepts. One example is the Penrose graphical notation which is used to show tensors. Another examples are Coxeter–Dynkin diagram which are used for certain problems of geometry.  view more...
