WebIn set theory, the union (denoted by ∪) of a collection of sets is the set of all elements in the collection. [1] It is one of the fundamental operations through which sets can be combined and related to each other. A nullary union refers to a union of zero ( ) sets and it is by definition equal to the empty set.

This expression worked for the sum for all of positive integers up to and including 1. And it also works if we assume that it works for everything up to k. Or if we assume it works for integer k it also works for the integer k plus 1. And we are done. That is our proof by induction.
