Time-value-of -money problems in Math for
Business and Life include solutions using (1) compound interest formulas,
(2) compound interest tables, (3) financial calculators, and (4) Excel.
This allows you to use your method(s) of choice. If you
use method 3 (financial calculators) with the HP10BII and/or TIBAII PLUS,
we may be able to get you one or more support products, compliments of
the calculator manufacturers:
- Financial calculator (HP 10BII or TI BAII PLUS)
- Overhead transparency of calculator keyboard
- Overhead calculator (a see-through operating calculator used with an
overhead projector)
- Calculator emulator (used with a computer and screen)
Contact the publisher for more details (facultysupport@olympuspub.com

If you use calculators to solve TVM problems, remember that we have an
operating TVM calculator on our website (see the navigation bar at the
left, CALCULATOR/TVM AIDS, Online Calculator). The online calculator can
be used to solve most of the problems in the text; it is not designed
to amortize or to solve cash flow problems (in which the payments change).
If you have your students use financial calculators to solve TVM problems,
here are some things to consider.
- Acceptable calculators. The text includes keystrokes for the
HP 10BII and TI BAII PLUS calculators. Both calculators are excellent
machines and do everything covered in the text. They each sell for around
$30. Here are a few basic differences. The HP 10BII has a larger display
(12 digits compared to 11), makes it easier to change the decimal setting
and, for most applications, requires fewer keystrokes. The TI BAII PLUS
uses worksheets, and while there are more keystrokes involved, it is
easier to review and change entries; it also has a few extra features,
such as depreciation, bond, and date applications. There are a few other
financial calculators that will work, including: HP 10B (the model that
preceded the HP 10BII), HP 12C, and the HP 17B. Some financial calculators
do not amortize accurately and cannot compute an IRR. Some graphic calculators
are equipped to do TVM problems, but require many more keystrokes. Our
website has calculator information and keystrokes for several popular
calculators (see the navigation bar at the left).
- Require a certain calculator? Some instructors insist that students
have a certain calculator, requiring only one set of classroom instructions.
Other instructors don't feel comfortable endorsing a particular brand,
and allow students to choose from several.
- Seating arrangements. You may find it helpful to have students with
similar calculators sit together. That way, you can address en entire
group of students at once. And, students with similar calculators can
help each other.
- Where can students get calculators?
- College bookstores. Prices may not be competitive, depending on
quantities the bookstore is able to purchase.
- Retail stores such as Staples (800-378-2753), Office Max (800-283-7674),
Office Depot (800-463-3768), etc. Also look in the yellow pages under
"Calculators" or "Office Supplies." You may want
to let selected retailers know when each term starts so they can
do their buying at the right time.
- New and used calculators can be purchased on the web, such as ebay.com
and Amazon.com. Students should be careful to get the current model.
- Manufacturers. Hewley Packard (888-999-4747), or Texas Instruments
(800-TI-CARES).
- Wholesalers. Valley (800-462-2019), Wholesale (800-880-9400), and
ElDorado (800-227-8292).
- Our Calculator Loaner Program. Students buy an HP 10BII or TI BAII
PLUS from us and get a refund when returned, except for a S&H
fee (currently $7). Details can be found by going to the navigation
bar at the left.
- Resale program. Students who have completed the course can resell
calculators (maybe through a bulletin board) to new students (for
about $5 less then they paid). This may not work smoothly, however,
because most students will not part with their calculator.
- School ownership. Your school may want to purchase a supply of
calculators and loan or rent to students each term.
