Using Calculator
The Calculator lets you perform general mathematical functions, such as addition,
subtraction, multiplication, division, and square root operation.
Using the Calculator buttons
The Calculator includes several buttons to help you perform calculations.
Displaying recent calculations
The Recent Calculations command lets you review the last series of calculations and
helps you confirm a chain of calculations.
To display recent calculations:
1 Tap the Menu icon . The Calculator menu bar appears.
Clears the entire calculation and enables you to begin a
fresh calculation.
Clears the last number you entered. Tap 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.
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. Tapping this button has no effect on the
current calculation (or series of calculations); it merely
places the value into memory until it is recalled.
Recalls the total stored value from memory and inserts it in
the current calculation.
Clears any value that is stored in the Calculator memory.
Calculates the square root of a number. Enter a number
then tap this 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 tap the +/- button.
