mathematical notation
Equations and formulas
Mathematical notation is the system of symbols used to express mathematical ideas—numbers, operations, relationships, and abstract concepts.
It includes numerals, operators (+, −, ×, ÷), letters representing variables, and specialized symbols for sets, functions, and logical relationships.
Good notation compresses complex ideas into compact, precise form: The equation E = mc² expresses mass-energy equivalence in five characters.
Notation evolves as mathematics does, with different conventions in different fields.
