Accessing Calculation History
The ` symbol in the upper right corner of the display indicates that there is data stored in

scroll upwards (back) one calculation, displaying both the calculation expression and its
result.
Example:

While scrolling through calculation history records, the
$ symbol will appear on the display,
which indicates that there are records below (newer than) the current one. When this symbol
is turned on, press
c to scroll downwards (forward) through calculation history records.
Important!
• Calculation history records are all cleared when you change to a different calculation
mode, or when you change the display format.
• Calculation history capacity is limited. Whenever you perform a new calculation while
calculation history is full, the oldest record in calculation history is deleted automatically to
make room for the new one.
Note
A calculation that contains any of the following functions is not stored in calculation history
when it is executed.
