# Value (mathematics)

In mathematics, **value** may refer to several, strongly related notions:

- The
**value**of a variable or a constant is any number or other mathematical object assigned to it. - The
**value**of a mathematical expression is the result of the computation described by this expression when the variables and constants in it are replaced by some numbers. - The
**value**of a function is the number implied by the function as a result of a particular number being assigned to its argument (also called the*variable*of the function).^{[1]}^{[2]}

For example, if the function is defined by , then, given the value 3 to the variable *x* yields the function value 10 (since indeed 2 · 3^{2} – 3 · 3 + 1 = 10). This is denoted
