In order to understand and communicate in mathematical terms and to lay the foundation for the
concepts and principles presented in this material, certain terms and expressions must be defined.
This section covers basic definitions used in mathematics. Once understood, such knowledge
should provide the foundation from which the principles of mathematics can be presented. By
no means are the terms here all inclusive; they are representative of those found within the
