Document Summary

Union of sets: the set of elements that are members of neither. The union of more than 2 sets is the set of all elements belonging to at least one of the sets. = and (the elements they have in common) Intersection: the set of elements common to both using the set builder notation. The intersection of more than two sets is the set of elements that belong to each other the sets is disjoint. Complement: the set outside or not included ( ) U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} Difference: of sets b and a is the set of elements that are in b but not in a. U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} a= {1, 2, 4, 7, 8} b = {1, 3, 4, 5, 8} E = {x:x is an even whole number less than 7}
