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  A B.


The intersection of the two intervals, is the set of elements which are in both set. This is denoted as A B.


Click or drag to place two intervals on the number line. Choose whether to include, exclude, or set your end points to ±. Use the check boxes on the right to show the two intervals, their union, and their intersection.
