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.

Setting the Default Calculator
The first time powerOne is run, it is set as the default calculator.
In other words, once you run the application once, it will
automatically set itself to run when the Calculator button is
selected. To set something else to be the default calculator, tap the
Applications button and choose Prefs. From the pull-down list in
the upper, right-hand corner, select Buttons. Next to the icon that
looks like a calculator, select the correct application from the popup list.
Removing the powerOne™ Calculator
To remove the powerOne calculator from the Palm device, select
the Applications button then the Menu button. Choose Delete
from the App menu. Finally, select pwrOne™ in the list and
finally the “Delete…” button. Select Done to return to the
Applications screen. The calculator button will reset to the built-in
calculator.
Number Ranges
The powerOne calculator allows for entry of numbers up to 10
digits. Numbers larger than this will display in scientific notation
(i.e., 1.234e13).

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.
Entering Numbers (0-9; ./,; +/–; ←←; CE/C)
To enter a number, tap the corresponding keypad button (0-9,
decimal point, or sign).
Performing Arithmetic
powerOne™ 7 Infinity Softworks
To enter -356.96, for instance, do the following:

. or , 356. Depends on the number format
9 356.9
6 356.96
+/– -356.96
The decimal point can either be displayed as a period or as a
comma. This depends on the number format mode used. See your
Palm device owner’s manual for more details.
The following are number entry functions:
Operation Example Comments

Decimal point . or , Depends on the number format
Sign +/–
The Backspace (←) button allows for editing of numbers as they
are entered. Tapping this button removes the last number entered
(i.e., 54.32 becomes 54.3).
Tapping the Clear Entry/Clear (CE/C) button once clears only
the currently entered number. Tapping it a second time clears the
entire computation.
