Calculation History
In the COMP Mode, the calculator remembers up to approximately 200 bytes
of data for the newest calculation. You can scroll through calculation history
contents using f and c.
1 + 1 = 2 1 + 1 = 2
2 + 2 = 4 2 + 2 = 4
3 + 3 = 6 3 + 3 = 6
(Scrolls back.) f 4
(Scrolls back again.) f 2
Note: Calculation history data is all cleared whenever you press O, when
you change to a different calculation mode, when you change the display
format, or whenever you perform any reset operation.
Replay
While a calculation result is on the display, you can press d or e to edit
the expression you used for the previous calculation.
4 × 3 + 2.5 = 14.5 b 4 * 3 + 2.5 = 14.5
4 × 3 − 7.1 = 4.9 (Continuing) dYYYY- 7.1 = 4.9
Note: If you want to edit a calculation when the ' indicator is on the right
side of a calculation result display (see “Reading the Display”), press A
and then use d and e to scroll the calculation.
Answer Memory (Ans)/Previous Answer Memory
(PreAns)
The last calculation result obtained is stored in Ans (answer) memory. The
calculation result obtained prior to the last one is stored in PreAns (previous
answer) memory. Displaying the result of a new calculation will move current
Ans memory contents to PreAns memory and store the new calculation
