How do you find an element in math?

The objects used to form a set are called its element or its members. Generally the elements of a set are written inside a pair of curly (idle) braces and are represented by commas. The name of the set is always written in capital letter. Here ‘A’ is the name of the set whose elements (members) are v w x y z.

What does this ∈ mean?

The symbol ∈ indicates set membership and means “is an element of” so that the statement x∈A means that x is an element of the set A. In other words x is one of the objects in the collection of (possibly many) objects in the set A.
