trigonometry, statistics and probability.

Fractions

P % @
Fractions with P can include real and complex numbers, operation keys (T, V, etc.),
and most function keys (F, % _, etc.).
In Classic mode or classic entries in MathPrint™ mode, the fraction bar P displays in-
line as a thick bar, for example
expect. While the Order of Operations rules will apply, you are in control of the way an
expression evaluates by placing the correct brackets in your inputs.
Fraction Results
• Fraction results are automatically simplified and output is in improper fraction
format.
• When mixed number output is desired, use the 4n/d³´Un/d mixed number
conversion at the end of the input expression. This feature is located in d 1:
4 n/d ³´ Un/d .
• Fraction results are obtained when the calculated value can display within the
limits of the fraction format supported by the calculator and no decimal value was
entered in the input expression.
• If decimal numbers are used or calculated in a fraction numerator or denominator,
the result will display as a decimal. Entering a decimal forces the result to display
in decimal format.

Mixed Numbers and Conversions
% @ enters a mixed number. Press the arrow keys to cycle through the unit,
•
numerator, and denominator.
d 1 converts between simple fractions and mixed-number form (4n/d³´Un/d).
•
• % j converts results between fractions and decimals.
MathPrint™ Entry
• To enter numbers or expressions in the numerator and denominator in MathPrint™
mode, press P.
Press $ or # to move the cursor between the numerator and denominator.
•
Pressing P before or after numbers or functions may pre-populate the numerator
•
with parts of your expression. Watch the screen as you press keys to ensure you
enter the expression exactly as needed.
