u Functions that Support Insertion
The following lists the functions that can be inserted using the procedure under “To insert a
function into an existing expression” (page 1-3-13). It also provides information about how
insertion affects the existing calculation.

u Editing Calculations in the Math Input Mode
The procedures for editing calculations in the Math input mode are basically the same as
those for the Linear input mode. For more information, see “Editing Calculations” (page
1-3-1).
Note however, that the following points are different between the Math input mode and the
Linear input mode.
•Overwrite mode input that is available in the Linear input mode is not supported by the
Math input mode. In the Math input mode, input is always
inserted
at the current cursor
location.
• In the Math input mode, pressing the D key always performs a backspace operation.
