Intersection Operator

Set Intersection Operator

The set intersection operation is denoted using the cap symbol. The intersection of two sets returns all of the elements common to both sets. For example, the intersection of the two sets and would be written in an expression like this:

Since both sets share the element and the element the resulting set contains both elements. The intersection operator can be visually represented as the shared space in the venn-diagram.
