In mathematics, a formal series is an infinite sum that is considered independently from any notion of convergence, and can be manipulated with the usual algebraic operations on series. A formal power series is a special kind of formal series, of the form
- ∑ n = 0 ∞ a n x n = a 0 + a 1 x + a 2 x 2 + ⋯, where the a n, called coefficients, are numbers or, more generally, elements of some ring, and the x n are formal powers of the symbol x that is called an indeterminate or, commonly, a variabl
