This book contains a treatment of arithmetic, algebra, and trigonometry, and an appendix on the slide rule. The text adapts to either review or first time coverage and is designed mainly for a junior college audience with no prerequisites necessary. Practical application is emphasized throughout, with a minimum of words used to explain concepts; this stress on demonstration over description is especially helpful for remedial students. Of particular interest is the textbook page with wide margins intended for exercises a feature that creates an opportunity for student reinforcement and eliminates the cost of an extra workbook.
