Answer Function
Answer function stores the most recently calculated result. It is
retained even after the power is turned off. Once a numeric value or
numeric expression is entered and [ M+ ], [ 2nd
] [ M– ], [ RCL ],
[ 2nd
] [ STO ] or [ = ] is pressed, the result is stored by this function.
See Example 15.
(Note) : Even if execution of a calculation results in an error,
however, Answer memory retains its current value.
Scientific Function Calculations
Use COMP ( [ MODE ] 1 ( COMP ) ) mode for scientific function
calculations.
Logarithmic and Exponential functions
The calculator can calculate common and natural logarithms, and
exponentiation using [ log ], [ ln ], [log
a
b], [ 2nd ] [ 10
x
], and [ 2nd ]
[ e
x
]. See Example 16~17.
Fraction calculation
Fraction value display is as follows:
Improper Fraction
Mixed Fraction
Math format:

Linear format:

(Note) : Values are automatically displayed in decimal format
whenever the total number of digits of a fractional value
( integer + numerator + denominator + separator marks )
exceeds 10.
In Linear mode, to enter a mixed number, enter the integer part,
press [ d/
e
], enter the numerator, press [ d/
e
], and enter the
denominator ; To enter an improper fraction, enter the numerator,
press [ d/
e
], and enter the denominator. See Example 18.
During a fraction calculation, if the figure is reducible, a figure is
reduced to the lowest terms after pressing the [ = ] key. The initial
default for a fraction result is improper fraction. By pressing [ 2nd ]
[ A
b
/
c
_`
d
/
e
], the displayed value will be converted to the mixed
fraction and vice versa. To convert between a decimal and fractional
result, press [ F
_`
D ]. See Example 19.
Calculations containing both fractions and decimals are calculated in
decimal format. See Example 20.
The initial default of the calculator is automatic simplification of
fraction produced by fraction calculations. When the fraction
simplification is set to manual, you can let the calculator
automatically selects the smallest possible divisor for simplification
or you can specify a divisor. See Example 21~22.
