SUMMARY

DeMorgan's Laws apply to infinite unions and intersections, confirming that for any set X and a collection of sets U_i, the equation X - ∩_{i=1}^{∞} U_i = ∪_{i=1}^{∞} (X - U_i) holds true. The proof for this relationship mirrors that of finite unions and intersections, establishing a consistent framework for set operations in both finite and infinite contexts. This conclusion is essential for understanding advanced set theory and its applications in mathematical logic.

I'm fairly certain the proof is exactly the same as it would be for a finite number
