Veranderlik Definisie

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.

As u algebraïese berekeninge met veranderlikes maak asof dit eksplisiet getalle is, kan u 'n reeks probleme in 'n enkele berekening oplos. 'N Tipiese voorbeeld is die kwadratiese formule , waardeur 'n mens elke kwadratiese vergelyking kan oplos deur die numeriese waardes van die koëffisiënte van die gegewe vergelyking te vervang vir die veranderlikes wat hulle voorstel.

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.
