Getting Started
General Information
This section helps you get started using your powerOne™
calculator.
The powerOne™ calculator
Welcome to the powerOne calculator. The powerOne calculator is
a colorful and easy-to-use calculator that gives you access to both
basic mathematics as well as more advanced functions. This
special edition includes computations for sales tax, percent change,
markup/discount, tip calculation, and calendar date computations.
In addition, it includes a calculation log to review past
mathematical functions. To access the worksheets, select either the
“Business” or “General” button and the worksheet to use. The
powerOne calculator also includes more advanced math function
by selecting the Math button.
The Display
The powerOne calculator has three functional areas: the main
calculator, the worksheets, and the input screen. The main and
input screens serve as calculators with arithmetic in the standard
mathematical format (3 + 4 = 7). The worksheets perform
computations, working with the input screen to enter variables and
perform arithmetic.

Performing Arithmetic
Performing Arithmetic
The main powerOne
calculator serves as a
standard calculator, which
functions in standard
(algebraic) input mode.
Entries made in the main
calculator tie to the input
screen, and vice-a-versa.
Functions are available
either on the screen or via
the “math” button.
Selecting “Business” or
“General” button displays
the list of available
worksheets. Other buttons function as standard calculator buttons.
In addition, there are menus. Reach the menu by tapping the menu
button to the lower, left of the Graffiti® input area.

Performing Arithmetic
Mathematics (One- and Two-Variable Functions)
The powerOne calculator can be used only in standard input mode.
Standard input mode math is performed by alternating chains of
values and operations.
Math functions are either one or two variable. Two-variable math,
such as add, subtract, multiply and divide, take two variables to
compute. One-variable functions, such as square root and
reciprocal (1/x), need only one variable to calculate.
Two-Variable Math
To perform a computation using standard input mode, enter
alternating values and functions. For example, if we wanted to
perform 27 + 3 x 8.5:

each worksheet for details on that specific computation. Finally,
see the appendix for information on errors.
Accessing the Worksheets
To access a worksheet, select the main screen button labeled
“Business” or “General” and choose the desired computation.
Worksheet Structure
All worksheets are similar in nature:
•Each worksheet has a clear button which sets the data back to
its original state.
•To exit the worksheet, select done.
•Most worksheets (excluding the calculation log) contain a
menu with two options: about the application and worksheet
help.

powerOne™ 14 Infinity Softworks
Using the Worksheets
The computation display for each worksheet is also similar.
For most worksheets, the data is set in column form:
To enter a value, tap on the label or value column, enter it in the
entry screen, and save. To compute a value, tap the “CPT” label
next to the data to compute.
Entering Data
In the worksheets, data is entered using the input screen, date
selector or time selector, depending on the type of data requested.
The date and time selectors are standard to the Palm Computing®
platform, used in applications such as the datebook and to do list.
The input screen is native to the powerOne calculator.
Input Screen
The input screen is used to enter values in the worksheets. All of
the math functions available on the main calculator are also
available in the input screen.

Using the Worksheets
When a value is selected, that value appears in the input screen.
The keyed function buttons work similar to those in the main
calculator. The only difference is memory, which is accessed by
selecting the “mem” button and choosing the function from the
pop-up list. See Performing Arithmetic for help with
understanding mathematical functions.
To exit the input screen, tap save to store the view window’s value
for worksheet calculations or tap cancel (“Cancl”) to disregard the
value. Some variables
cannot be saved. In this
case, the worksheet
disregards the value
whether save or cancel is
selected. Remember, the
computations done in the
worksheet itself are
automatically saved for
further use within the input screen or in the main calculator. Save
and cancel are specifically used for saving to the worksheet itself.

Sales Tax
The sales tax worksheet
computes tax before or after
sales tax, or the tax rate itself.
•Before Tax: the amount
before taxes.
•Tax Rate%: the tax rate as
a percentage.
•After Tax: the amount after
taxes.
Example: The local tax rate is 5.5% You have a maximum of $70
to spend on clothing. What is the maximum amount of clothing
you can purchase and still have enough to pay for the tax?
Key Entry Comments
