The notion of a set is one of the m

The notion of a set is one of the most basic concepts in all of mathematics.
We begin our discussion with some set-theoretic terminology and a few
facts from the algebra of sets. A set is a collection of well-defined objects
(e.g., numbers, vectors, functions) and is usually designated by a capital letter
A, B, C, . . . , X, Y, Z. If A is a set, we write a ∈ A to express “a is an
element (or member) of A” or “a belongs to A.” Likewise, the expression
a /∈ A means “a is not an element of A” or “a does not belong to A.” For
instance, A = {a, b} means that A consists of a and b, while the set A = {a}
consists of a alone. We use the symbol “∅” to denote the empty set, that is,
the set with no elements.
