Basic Applications Overview: 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 Applications Launcher icon, and 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.
