Fractions

Keep in mind when inputting fractions on your calculator that the input procedure you need
to use depends on whether natural display or linear display is selected as the display format
(page 11), as shown below.

textbook, while linear display requires input of a special symbol ( ).
Note
• Under initial default settings, fractions are displayed as improper fractions.
• Fraction calculation results are always reduced automatically before being displayed.
