The primary goal of *Business Algebra* is to bring as simple, organized and straight-forward of an approach to business algebra as possible. Many students are somewhat mathemaphobic and are intimidated by mathematics textbooks. They typically don’t have a great desire (or any at all) to read all the text of the sections in a mathematics book, but they desperately want to review the examples in detail in order to increase their own understanding of the material. Thus, this publication contains only what’s necessary and gives plenty of examples with every step outlined so students may get maximum use from the text. It contains answers to every homework problem in the end of the book to provide feedback for all homework, not just half of the problems.
