# Thread: Discrete Mathematics in Set Identities

1. ## Discrete Mathematics in Set Identities

Proving Set Identities
1) (A intersection B)U(A intersection B complement)U (A intersection B)=A
using commutative identities
2) (A intersection B)U(A intersection B complement)=A
using distributive identities
3) (complement A-B)=(complement A U B)
using by diff.
