The functions of the Calculator buttons
Calculator has several buttons to help you perform calculations.
CE Clears the last number you entered.
Use this button if you make a mistake while entering
numbers. This button enables you to re-enter the number
without starting the calculation again.
C Clears the entire calculation and enables you to start a
new calculation.
+/- Toggles the current number between positive and
negative. If you want to enter a negative number, enter
the number and then tap the +/- button.
M+ Adds the current number to the total value in the
memory. Each number you enter with the M+ button is
added to the total value stored in the memory. The
number to be added can be either a calculated value or
the number you entered 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 the memory until it is recalled.
MR Recalls the total value stored in the memory and inserts
it in the current calculation.
MC Clears any value that is stored in the Calculator memory.
Calculates the square root of the entered number.
Tap the button after entering the number.
