Question

what is symmetric difference​

Answer 1

Answer:

In mathematics, the symmetric difference, also known as the disjunctive union, of two sets is the set of elements which are in either of the sets and not in their intersection. The symmetric difference of the sets A and B is commonly denoted by or or For example, the symmetric difference of the sets and is.

Answer 2

Answer:

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

For example, the symmetric difference of the sets \text{{1,2,3}}1,2,3 and \text{{3,4}}3,4 is \text{{1,2,4}}1,2,4.
