We can perform the following operations on sets:

**Union**: Given two sets, this returns a new set with elements from both the given sets**Intersection**: Given two sets, this returns a new set with the elements that exist in both sets**Difference**: Given two sets, this returns a new set with all the elements that exist in the first set and do not exist in the second set**Subset**: This confirms whether a given set is a subset of another set

The mathematic concept of **union** is: the union of sets *A* and *B*, denoted by*:*

This set is defined as*:*

This means that *x* (the element) exists in *A* or *x* exists in *B*. The following diagram exemplifies the ...
