What practical applications are offered in history, philosophy, geography?
I have a 1922 edition of a high school algebra book used by my uncle and
father (both highly successful in math/engineering type activities).
Except for the lack of inequalities and set theory, I could use the
contents for my beginning-level algebra classes (although some of the
algorisms are too tough--it includes the cube root algorism, for example).
And it contains NO practical problems at all. I wonder how we managed to
survive back then... ;-)

John M. Flanigan <johnf@hawaii.edu> The equation is the final arbiter.
Assistant Professor, Mathematics --Werner Heisenberg
Kapi'olani Community College The scoreboard is the final arbiter.
4303 Diamond Head Road --Bill Walton
Honolulu HI 96816 History is the final arbiter.
(808) 734-9371 --Edward Gibbon
