Correcting an Expression

This section explains how to correct an expression as you are inputting it. The procedure you should use depends on whether you have insert or overwrite selected as the input mode.

About Insert and Overwrite Input Modes

In insert mode, the displayed characters shift to the left to make room when your input replaces the character at the current cursor position. The initial default input mode is insert. You can change to overwrite mode as needed.

•The cursor is a vertical flashing line ( ❙ ) when insert mode is selected. The cursor is a horizontal flashing line ( _ ) when overwrite mode is selected.

•The initial default for Linear format input is insert mode. You can switch to overwrite mode by pressing  (INS)

•In Math format, you can only use insert mode. Pressing (INS) when Math format is selected does not switch to overwrite mode. See “Incorporating a Value into a Function” for more information.

•The calculator automatically changes to insert mode whenever you change the input/output format from Linear to Math.

Changing the Character or Function You Just Input

Example: To correct the expression 369 ✕ 13 so it becomes 369 ✕ 12.
