BASIC APPLICATIONS > USING THE CALCULATOR
Using the Calculator
The Calculator lets you perform general mathematical functions, such as addition, subtraction, multiplication, and division.
Use the Calculator to do the following:
• Perform basic calculations.
• Store and retrieve values.
• Display the last series of calculations, which is useful for confirming a series of “chain” calculations.
To open the Calculator:
Tap the Home icon
. Select All from the pick list in the upper-right corner. Then tap the Calculator icon.
Using the Calculator Buttons
The Calculator includes several buttons to help you perform calculations.
The CE button 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.
The C button clears the entire calculation and allows you to begin a fresh calculation.
The Plus/Minus button 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.
The M+ button places the current number in memory. Each new number you enter with the M+ button is added to the total stored
in memory. The number that you add can be either a calculated value or any 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.
The MR button recalls the stored value from memory and inserts it in the current calculation.
The MC button clears any value that is stored in the Calculator memory.
