The Combinations Calculator will find the number of possible combinations that can be obtained by taking a sample of items from a larger set. Basically, it shows how many different possible subsets can be made from the larger set. For this calculator, the order of the items chosen in the subset does not matter.

Digit Sum. Download Wolfram Notebook. A digit sum is a sum of the base- digits of . The base-10 digit sum of the integer will be implemented in a future version of the Wolfram Language as DigitSum [ n ], and the base- digit sum as DigitSum [ n, b ]. The following table gives for , 2, ... and small .An equation is said to be a closed-form solution if it solves a given problem in terms of functions and mathematical operations from a given generally-accepted set. For example, an infinite sum would generally not be considered closed-form. However, the choice of what to call closed-form and what not is rather arbitrary since a new "closed-form" function could simply be defined in terms of the ...Calculator for double sums, the connections of two sums, an inner and an outer sum.

Wolfram|Alpha brings expert-level knowledge and capabilities to the broadest possible range of people—spanning all professions and education levels.This means that the sum can be made as large as desired by adding enough terms. Suppose we delete from this series all terms with a "9" in the denominator. That is, we remove 1/9, 1/19, 1/29, etc. Then the remaining series converges to a sum less than 80. This very surprising result was proved by A. J. Kempner in 1914. maricopa jail mugshotssec college football scoreskctv5 rainfall totals Complex Numbers. Complex numbers are numbers of the form a + ⅈb, where a and b are real and ⅈ is the imaginary unit.
