That is, assume for some set A, A ∩ ∅ ≠ ∅. By definition of the empty set, this means there is an element in A ∩ ∅. Let x ∈ A ∩ ∅. x ∈ A ∧ x ∈ ∅ by definition of intersection. This says x ∈ ∅, but the empty set has no elements! This is a contradiction! Thus, our assumption is false, and the original statement is true.
