Sets A, B, and C are groups of elements or objects. They can be numbers, letters, or even other sets. Each set is denoted by curly braces { } and the elements are separated by commas.
The intersection of sets A and B is the set of elements that are common to both sets. In other words, it is the elements that are present in both sets A and B.
The intersection of sets A and B is represented by the symbol ∩.
The difference between sets A and B is the set of elements that are present in set A but not in set B. In other words, it is the elements that are unique to set A.
The difference between sets A and B is represented by the symbol \. So the difference of set A and B would be written as A \ B.
