Intersection and Union
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 two sets or intervals, A and B, is the set of elements which are in both sets. This is denoted as A ⋂B.
Drag to place two intervals on the number line. Choose whether to include, exclude, or set your endpoints to ±∞. Use the check boxes on the right to show the two intervals, their union, and their intersection.
