The symbol "∪" is known as the union symbol and is used to denote the combination of elements from two or more groups. In other words, it represents the set of all elements that are present in any of the given groups.
The symbol "∩" is called the intersection symbol and is used to denote the common elements shared by two or more groups. It represents the set of all elements that are present in all of the given groups.
The symbol "⊂" is known as the subset symbol and is used to indicate that one group is a subset of another group. In other words, all the elements of the first group are also present in the second group.
The symbol "Σ" is known as the summation symbol and is used to denote the sum of all elements in a group. It is often used in mathematical equations to calculate the total value of a set of numbers.
The symbol "∅" is called the empty set symbol and is used to represent a group with no elements. It is often used in mathematical proofs and to represent the absence of any elements in a particular context.
