Code to add this calci to your website  Powersets: The power set is the set of all subsets of a given set. A set with n elements will have 2n subsets. The subset (or powerset) of any set S is written as P(S), P(S), P(S),P(S) or 2S. The power set must be larger than the original set and is closely related to the binomial theorem. The number of subsets with k elements in the power set of a set with n elements is given by the number of combinations, C(n, k), also called binomial coefficients.

Number of Subsets Calculator: Just enter the values for a set separated by a comma in this algebra calculator and you could calculate the number of subsets (powersets) in a set within the fractions of seconds.
