After you press A, you can press f or c to recall previous calculations, in sequence from
the newest to the oldest (Multi-Replay Function). Once you recall a calculation, you can use
e and d to move the cursor around the calculation and make changes in it to create a new
calculation.
Example 2
• A calculation remains stored in replay memory until you perform another calculation.
• The contents of replay memory are not cleared when you press the A key, so you can
recall a calculation and execute it even after pressing the A key.
