$\text{A△B}$ or $\text{A⊖B}$ or $\text{A}{\oplus}{B}.$ Using set notation, we can also denote this as $(A\cup B)-(A\cap B).$ Symmetric difference is also known as disjunctive union.

The symmetric difference of set A with respect to set B is the set of elements which are in either of the sets A and B, but not in their intersection. This is denoted asFor example, the symmetric difference of the sets $\text{{1,2,3}}$ and $\text{{3,4}}$ is $\text{{1,2,4}}$.
