WebThe 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)]. The set difference between two sets A and B, denoted by A − B, is the set of elements that can only be found in A but not in B. In symbols, it means ∀x ∈ U [x ∈ A − B ⇔ (x ∈ A ∧ x ∉ B)].
