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.
Primary Arithmetic
Reading, writing and understanding numbers to 100; adding and subtracting
with sums to 20; multiplication and division to 10s.
