Calculation History
In the COMP, CMPLX, or BASE-N 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
2 + 2 = 4
3 + 3 = 6
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 − 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.
