Difference of two sets
From Encyclopedia of Mathematics
An operation on sets. Let $A$ and $B$ be two sets (where the second need not be contained in the first). Then the set of those elements of $A$ that are not elements of $B$ is called the difference of these sets.
The difference between two sets $A$ and $B$ is denoted by $A\setminus B$.
