Interval operations:

• Union:
• If AA and BB are two intervals, then the union A∪BA∪B is defined as the set of points xx that are in the interval AA or in the interval BB or in both intervals:
• A∪B = {x | x∈A∨x∈B}
• 

Intersection:

• 
• If AA and BB are two intervals, then the intersection A∩BA∩B is defined as the set of points xx that are in the interval AA and in the interval BB. That is, it is the set of points that are in both intervals:
• A∩B = {x | x∈A∧x∈B}

Difference and complement

• 
• It is the set formed by the elements that the set lacks to be equal to the universal set
