Set Theory Identities

Sets: A, B, C
Universal Set: I
Complement: A’
Proper Subset: A ⊂ B
Empty Set: ∅
Union of Sets: A ∪ B
Intersection of Sets: A ∩ B
Difference of Set: A\B

Set Theory Formulas

A⊂I
A⊂A
A=B if A⊂B and B⊂A
Empty Set: ∅⊂A
Union of Sets: C = A∪B = {X|X∈A or X∈B}
Union of Commutative Sets: A∪B = B∪A
Union of Associativity Sets: A∪(B∪C) = (A∪B)∪C
Intersection of Sets: C = A∩B = {X|X∈A or X∈B}
Intersection of Commutative Sets: A∩B = B∩A
Intersection of Associativity Sets: A∩(B∩C) = (A∩B)∩C
Distributive: A∪(B∩C) = (A∪B)∩(A∪C) and A∩(B∪C) = (A∩B)∪(A∩C)
Idempotency: A∪A = A, A∪A = A
Domination: A∩∅ = ∅, A∪I = I
Identity: A∪∅ = A, A∩I = A
Complement = A’= {X∈I|X∉A}
Complement of intersection and Union: A∪A’ = I, A∩A’ = ∅
De Morgan’s Law: (A∪B)’ = A’∩B’, (A∩B)’ = A’∪B’
Difference Sets: C = B\A = {X|X∈B or X∉A}
B\A = B\(A∩B)
B\A = B∩A’
A\A = ∅
A\B = A if A∩B = ∅
(A\B)∩C=(A∩C)\(B∩C)
A’ = I\A
Cartesian Product : C = A X B = {(x,y)| X∈A and y∈B}
