This module is from Elementary Algebra by Denny Burzynski and Wade Ellis, Jr.
The symbols, notations, and properties of numbers that form the basis of algebra, as well as exponents and the rules of exponents, are introduced in this chapter. Each property of real numbers and the rules of exponents are expressed both symbolically and literally. Literal explanations are included because symbolic explanations alone may be difficult for a student to interpret.This module provides a summary of the key concepts of the chapter "Basic Properties of Real Numbers".

Grouping symbols are used to indicate that a particular collection of numbers and meaningful operations is to be considered as a single number (
is not meaningful). Grouping symbols can also direct us in operations when more than two operations are to be performed. Common algebraic grouping symbols are
When two or more operations are to be performed on a collection of numbers, the correct value can be obtained only by using the correct order of operations.
The number associated with a point on the number line is called the
coordinate of the point. The point associated with a number is called the
graph of the number.
