The null set makes it possible to explicitly define the results of operations on certain sets that would otherwise not be explicitly definable. The intersection of two disjoint sets (two sets that contain no elements in common) is the null set. For example:

{1, 3, 5, 7, 9, ...} {2, 4, 6, 8, 10, ...} = $\theta$

▶The empty (or void, or null) set, symbolized by {} or Ø, contains no elements at all.
