What you need to know about properties, order of operations, exponents, roots and polynomials before starting algebra.

What you will learn

### Students will learn about absolute value operations.

Description

This course is designed for anyone at least 18 years of age starting an algebra course.  This course can even be used for adults or parents wanting to learn algebra for their own edification or to help the own children with these topics.  Although it covers some pre-algebra topics, it also goes into basic algebra topics so that upon enrolling in an algebra course, the student will be conversant and knowledgable in those topics.  Included in this free course are:

-Numbers:  a basic description of the development of the number system including integers, rational and irrational numbers.

-Properties:  Includes a description and examples of the basic mathematical properties used in algebra, i.e. commutative, associative, symmetric, distributive, transitive, substitution, inverse, identity, zero product and properties of equality.

– Order of operations: describes use of order of mathematical operations using the acronym PEMDAS.

– Exponents and roots: Defines exponents and roots and their relationship.

– Absolute Value: Describes absolute value and how to solve for various equations involving absolute values expressions.

-Variable of Interest:  Using mostly properties of equality, shows how to solve for a single variable in a multivariable equation scenario.

This free course can be used as a refresher at all levels or it can be used for students seeing these topics for the first time to help with the more challenging topics in a full algebra course.
