Calculator
Calculator includes two operating modes: Basic and Advanced. In 
Basic mode you can perform simple mathematical calculations. In 
Advanced mode you can access scientific functions and perform 
sophisticated math calculations. This section explains how to select 
the operating mode and use the buttons and menu options available 
in each mode.
Selecting the Calculator mode
The Change Mode dialog enables you to choose whether you want to 
work in Basic Calculator mode or Advanced Calculator mode. You 
can change modes at any time.
To select the Calculator mode:
1. Tap the Calculator icon   next to the Graffiti® writing area.
2. Tap the Menu icon  .
3. Tap Options, and then tap Change Mode.
4. Tap Basic or Advanced as the mode.
5. Tap OK.
Using the Basic Calculator buttons
The Basic Calculator includes the following buttons.
Clears the last number you entered. Use this button if 
you make a mistake while entering a number in the 
middle of a calculation. This button enables you to re-
enter the number without starting the calculation over.
Clears the entire calculation and enables you to begin a 
fresh calculation.
Toggles the current number between a negative and 
positive value. If you want to enter a negative number, 
enter the number first and then press the +/- button.
Places the current number in memory. Each new 
number you enter with the M+ button is added to the total 
already stored in memory. You can add either a 
calculated value or a number you enter by pressing the 
number buttons. Pressing this button has no effect on 
the current calculation (or series of calculations); it 
merely places the value into memory until it is recalled.

Displaying Recent Calculations
The Basic Calculator’s Recent Calculations command enables you to 
review the last series of calculations and is particularly useful for 
confirming a series of “chain” calculations.
To display recent calculations:
1. Tap the Menu icon  .
2. Tap Options, and then tap Recent Calculations.
3. After you finish reviewing the calculations, tap OK.
Using the Advanced Calculator mode
The Advanced Calculator screen consists of three regions. Each region 
performs a different function to help you perform a variety of 
calculations.Recalls the stored value from memory and inserts it in 
the current calculation.
Clears any value that is stored in the Calculator 
memory.
