– 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:Â  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.
