Set Difference Notation

The minus symbol is used in set theory to represent the difference operator for two sets. The operation removes all elements found in one set from another and returns the resulting set.


For example, the difference of the two sets A and B is denoted as:

If A = { w, x, y} and B = { x, y, z} then the operation removes the elements {x, y} from set A.
