Ufitzeg Defininitioun

In mathematics, a variable is a symbol used to represent an arbitrary element that can change or that may take on different values. Variables may also refer to a letter, symbol, or snippet of words or text, representing such a quantity. In addition to numbers, variables are commonly used to represent vectors, matrices and functions.

Maacht algebraesch Berechnunge mat Variabelen wéi wa se explizit Zuelen eng Rei Problemer an enger eenzeger Berechnung ze léisen. En typesch Beispill ass den Quadratesch Formel , wéi ee fir all Quadratesch Equatioun ze léisen andeems se nëmmen eng quadratesch Wäerter vun der numerescher Wäerter sinn Koeffizique fir d'Variabelen déi se representéieren.

In mathematical logic, a variable is either a symbol representing an unspecified term of the theory, or a basic object of the theory, which is manipulated without referring to its possible intuitive interpretation.
