Calculator
The Calculator includes several buttons to help you perform calculations.
Clears the entire calculation and enables you to begin a fresh
calculation.
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.
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. 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.
Recalls the 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 the number, then tap
the square root button.
