k Using Undoing and Redoing Operations
You can use the following procedures during calculation expression input in the Math input/
output mode (up until you press the w key) to undo the last key operation and to redo the
key operation you have just undone.
- To undo the last key operation, press: aD(UNDO).
- To redo a key operation you have just undone, press: aD(UNDO) again.
• You also can use UNDO to cancel an A key operation. After pressing A to clear an
expression you have input, pressing aD(UNDO) will restore what was on the display
before you pressed A.
• You also can use UNDO to cancel a cursor key operation. If you press e during input and
then press aD(UNDO), the cursor will return to where it was before you pressed e.
• The UNDO operation is disabled while the keyboard is alpha-locked. Pressing
aD(UNDO) while the keyboard is alpha-locked will perform the same delete operation
as the D key alone.
Example

k Math Input/Output Mode Calculation Result Display
Fractions, matrices, vectors, and lists produced by Math input/output mode calculations are
displayed in natural format, just as they appear in your textbook.
Sample Calculation Result Displays
• Fractions are displayed either as improper fractions or mixed fractions, depending on the
“Frac Result” setting on the Setup screen. For details, see “Using the Setup Screen” (page
1-30).
•
Matrices are displayed in natural format, up to 6 × 6. A matrix that has more than six rows or
columns will be displayed on a MatAns screen, which is the same screen used in the Linear
input/output mode.
