Calculator
The Calculator includes several buttons to help you perform calculations.
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. 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.
