Most chemistry textbooks introduce students to the mathematics of chemistry, such as scientific notation, significant digits, and unit conversions.  However, many students need to review and practice other mathematical topics, such as powers of ten, metric prefixes and conversions, determining when conversions are exact or measured, solving equations for a variable, and canceling units.  This book contains tutorials on these topics, as well as links to more practice problems.  It is suitable for any beginning introductory or general chemistry student.
