If Ais a set and y is one of the objects in the set A, we write y \in A and read this as “y is an element of A” or “y is a member of A.” For example, if B is the se...If Ais a set and y is one of the objects in the set A, we write y \in A and read this as “y is an element of A” or “y is a member of A.” For example, if B is the set of all integers greater than 4, then we could write 5 \in B and 10 \in B.
