Editing an expression

After obtaining an answer, you can go back to an expression and modify it
using the cursor keys just as you can before the e is pressed.

8 ÷ 3 – 7 × -10.5
Press d or r to return to the

the expression (on '8' in this case).
• Pressing u or l after obtaining
an answer returns the cursor to the end
of the last expression.
• To make the cursor easier to see in diagrams throughout the manual,
it is depicted as '_' under the character though it may actually appear
as a rectangular cursor on the display.
Press r four times to move the
2.

make a change.

• When @ is pressed the 2ndF symbol should appear at the above

enough.

mode you are in. A triangular cursor indicates 'insert' mode while a
rectangular cursor indicates 'overwrite' mode.
Press ( and then move the cursor
