Webb26 nov. 2013 · A nine-item list of rules called Zermelo-Fraenkel set theory with the axiom of choice, or ZFC, was established and widely adopted by the 1920s. Translated into plain English, one of the axioms says two sets are equal if they contain the same elements. Another simply asserts that infinite sets exist. WebbThe rules that determine the order of evaluation in a set expression that involves more than one operation are similar to the rules for logic. In the absence of parentheses, complementations are done first, intersections second, and unions third. Parentheses are used to override this order.

WebbThe union of two sets A and B, denoted A ∪ B, is the set that combines all the elements in A and B. In symbols, ∀x ∈ U [x ∈ A ∪ B ⇔ (x ∈ A ∨ x ∈ B)].

For example, let x be an element from the set A U (B U C), then x is an element of A or x is an element of (B U C).
