Table 1-2. Keys for Clearing
Key Description
<
Backspace; erases the character before the cursor.
C
Clear; clears the calculator line. (When the calculator
is off, this key turns the calculator on, but without
clearing anything.)
@c
This clears all information in the current work area
(menu). For example, it will erase all the numbers in
a list if you are currently viewing a list (SUM or
CFLO). In other menus (like TVM),
@c
clears
all of the values that have been stored. In SOLVE, it
can delete all equations.
The cursor ( ) is visible while you are keying in a number or doing a
calculation. When the cursor is visible, pressing
<
deletes the last
character you keyed in. When the cursor is not visible, pressing
<
erases the last number.

In addition, there are more drastic clearing operations that erase more
information at once. Refer to “Resetting the Calculator” on page 228 in
appendix A.
