Union (set theory) - Wikipedia
WEBThe union of A, B, C, D, and E is everything except the white area. In 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 …
4.3: Unions and Intersections - Mathematics LibreTexts
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 …
Union and Intersection | Brilliant Math & Science Wiki
WEBThe union of 2 sets A A and B B is denoted by A \cup B A∪B. This is the set of all distinct elements that are in A A or B B. A useful way to remember the symbol is \cup ∪ nion. We can define the union of a collection of sets, as the set …

WEBUnion, Interection, and Complement. The union of two sets contains all the elements contained in either set (or both sets). The union is notated A ∪ B A ∪ B. More formally, x ∈ A ∪ B x ∈ A ∪ B if x ∈ A x ∈ A or x ∈ B x ∈ B (or both) The intersection of two sets contains only the elements that are in both sets.
The "Union (∪)" Symbol in Mathematics
WEBIn set theory, the ∪ symbol is used to show the union of two sets, resulting in a new set that contains all the elements from both constituent sets. If an element belongs to either one of the sets (or both), it will belong to their union.
