Basic Dozenal Arithmetic
Donald P. Goodman III
Arithmetic has both fascinated and terrified students
for countless generations. A big part of that fright,
though, has been due to the use of decimal numbering.
The more or less chaotic multiplication tables; the lack of
easy factors, particularly for thirds; and, most of all,
the lack of adequate explanation of the place notation
system in general have served to make arithmetic, and by
extension mathematics, an opaque subject full of magical
spells that, when executed properly, will give the right
result, but which are only imperfectly understood.
This text starts from the very beginning, with counting;
explains place notation along with other notational
systems; and goes through basic and advanced arithmetic
step-by-step, with examples and exercises. Featuring
answers to the exercises; a complete glossary; a table of
definitions; an appendix of tables; and recommendations
for further reading, the adult student should need no
other text.
