Using Calculation History

Memory and Replay (COMP)

Calculation history memory maintains a record of each calculation

expression you input and execute, and its result.

You can use calculation history memory in the COMP Mode

(N1) only.

Recalling Calculation History Memory Contents

Press f to back-step through calculation history memory contents.

Calculation history memory shows both calculation expressions and

results.

Example:

LINE

1+1=

2+2=

3+3=

• Note that calculation history memory contents are cleared

whenever you turn off the calculator, press the O key, change to

the calculation mode or the input/output format, or perform any

reset operation.

•Calculation history memory is limited. When the calculation you

are performing causes calculation history memory to become full,

the oldest calculation is deleted automatically to make room for

the new calculation.

Replay Function

While a calculation result is on the display, you can press A and

then d or e to edit the expression you used for the previous

calculation. If you are using Linear format, you can display the

expression by pressing d or e, without pressing A first.
