Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the logical equivalence?Corresponds to the logical AND (conjunction) operator
2. What is the computational use?Fundamental in database queries, algorithms, and Boolean logic systems
3. What is the intersection of two sets?Intersection is the group of items that are in both sets. It shows what is the same in each group.
4. How do we write the intersection of sets A and B?We write it as A ∩ B. It means all items that belong to A and also belong to B.

Set: A well-defined collection of distinct objects, considered as an object in its own right.
Intersection (A ∩ B): The set comprising elements that are members of both set A and set B.
