For other uses, see Coefficient (disambiguation).

In mathematics, a **coefficient** is a constant multiplicative factor of a certain object. For example, the coefficient in *9x*^{2} is *9*. A coefficient can also be a variable such as [math]a[/math], [math]b[/math] and [math]c[/math].^{[1]}^{[2]}

The object can be such things as a variable, a vector, a function, etc. In some cases, the objects and the coefficients are indexed similarly, leading to expressions such as:

- [math]a_1 x_1 + a_2 x_2 + a_3 x_3 + \cdots [/math]

where *a*_{n} is the coefficient of the variable *x*_{n} for each *n* = 1, 2, 3, …^{[3]}
