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

- A
**value**of a variable or a constant is any number or other mathematical object assigned to it. - A
**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 values. - A
**value**of a function is the result associated to a value of its argument (also called*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
