The best explanation that could be given to the mathematical statement a ∈ A is that "a is an element of A."
A set is a group of objects. The objects are referred to as the set's elements. A set is said to be a finite set if it has a finite number of items; else, it is an infinite set. We can simply list the elements of a set if there aren't too many of them.
The elements of a set are those things that make up the set. The elements of a set are often denoted by commas and expressed inside a pair of curly braces. The set expressing these elements is always stated in capital letters.
So, if we have a set A with the following parameters a, b, c. We can mathematically express it as:
Thus, we can conclude that a ∈ A i.e "a is an element of A."
