Technical Information
Calculation History and Replay
Calculation History
In the COMP, CMPLX, or BASE Mode, the calculator remembers up to approximately 150 bytes of data for the newest calculation.
An and/or at the top of the display indicates that there is more calculation history content above and/or below.
You can scroll through calculation history contents using and .
Example:
-
1 + 1 = 2 11
- 2.
-
2 + 2 = 4 22
- 4.
-
3 + 3 = 6 33
- 6.
- (Scrolls back.)
- 4.
- (Scrolls back again.)
- 2.
Note
Calculation history data is all cleared whenever you press , when you change to a different calculation mode, or whenever you initialize modes and settings.
Replay Copy
Replay copy lets you recall multiple expressions from replay so they are connected as a multi-statement on the screen.
Example:
Replay memory contents:
1 + 1
2 + 2
3 + 3
4 + 4
5 + 5
6 + 6
Multi-statement: 4 + 4 : 5 + 5 : 6 + 6
Use and to display the expression 4 + 4.
Press (COPY).

- (COPY)
Note
You can also edit expressions on the display and perform other multi-statement operations. For more details about using multi-statements, see "Multi-statements."
Only the expressions in replay memory starting from the currently displayed expression and continuing to the last expression are copied. Anything before the displayed expression is not copied.
Replay
While a calculation result is on the display, you can press or to edit the expression you used for the previous calculation.
Example: 4 × 3 + 2 = 14
Example: 4 × 3 - 7 = 5
- 432
- 14.
- (Continuing) 7
- 5.
