Inputting and Editing Calculations

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 1-3-15). It also provides information about how insertion affects the existing calculation.

uEditing 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.
