entering a number in the middle of a calculation, you can use this
button to reenter 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 into 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 into the current
calculation.
