The symbol “∈” is used in mathematics to denote “belongs to” or “is an element of.” It is used to indicate that a particular object is a member or part of a set.
For example, if we have a set A = {2, 4, 6, 8}, we can say that the number 4 ∈ A. This means that 4 is an element of the set A. Similarly, if we have a set B = {red, green, blue}, we can say that the color red ∈ B, indicating that red is one of the elements in the set B.
In set theory, the symbol “∈” is used to establish membership and distinguish between elements and sets. It helps to define relationships between objects and sets within the framework of mathematical logic.
