Using Basic Applications
C
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.
M+
Places the current number in the memory. Each new number you enter with
the M+ button is added to the total stored in memory. The number that you
add can be either a calculated value or any 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 stored value from the memory and inserts it into the current
calculation.
MC
Clears any value that is stored in the Calculator memory.
