Ray's Arithmetic 8 Volume Set

By Joseph Ray, Mott Media

Used in the 1800's, Ray's Arithmetic taught math to generations. This set presents principles and follow up each one with examples which include difficult problems to challenge the best students. Students who do not master a concept the first time can return to it later, work the more difficult problems, and master the concepts. Thus in these compact volumes is a complete arithmetic course to study in school, to help in preparation for ACT and SAT tests, and to use for reference throughout a lifetime.
