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.
