210 Calculator
The “M+” button places the current number in
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 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.
The “MR” button recalls the stored value from
memory and inserts it in the current calculation.
The “MC” button clears any value that is stored in
the Calculator memory.
Displaying Recent Calculations
The Recent Calculations command lets you review the last
series of calculations and helps you confirm a chain of
calculations. Recent calculations include the number of
characters that can fit on the screen. Once the characters scroll
from the screen, they are lost.
To display recent calculations:
1. In the Calculator application, tap the Menu icon.
2. Tap “Options”, and then tap “Recent Calculations”.
