u Editing Calculations in the Math Input/Output Mode
The procedures for editing calculations in the Math input/output mode are basically the same
as those for the Linear input/output mode. For more information, see “Editing Calculations”
(page 1-7).
Note however, that the following points are different between the Math input/output mode and
the Linear input/output mode.
• Overwrite mode input that is available in the Linear input/output mode is not supported by
the Math input/output mode. In the Math input/output mode, input is always inserted at the
current cursor location.
• In the Math input/output mode, pressing the D key always performs a backspace operation.
