Intersection and Union

 Main Concept Given two intervals, the two major relations between them are their union and their intersection.   The union of two sets or intervals, $A$ and $B$, is the set of elements which are in either set. This is denoted as .   The intersection of two sets or intervals, $A$ and $B$, is the set of elements which are in both sets. This is denoted as .

Drag to place two intervals on the number line. Choose whether to include, exclude, or set your endpoints to $\mathit{±}\mathit{\infty }$. Use the check boxes on the right to show the two intervals, their union, and their intersection.
