There seems to be something about financial calculations that boggles minds. I've taught finance
courses for years and I'd guess that less than 20% of introductory students finish with a solid working
knowledge of the fundemental equation. Now Messrs. Coffin and Wadman have written a book whose
great value is not its explanation of a particular calculator, but its graphic presentation and detailed
explanation of basic present value/future value calculations.
Coffin and Wadman don't skimp in explaining the machine itself—the first sixty pages deal with
Hewlett-Packard's stack manipulation. Still, this is widely popular financial calculator, and this subject
gets the book's remaining 70 pages. Persons who do have a good gut feel for PV/FV manipulations can
skip this book entirely, but if you've just been issued an HP-12C for your line of work (as many of my
students have) here's where you want to dig in.
