 Independent Memory
 Independent memory M uses the same memory area as variable M. It is
convenient for calculating cumulative totals by just pressing M+ (add to
memory) or M- (subtract from memory),
 Memory contents are retained even when the calculator is powered off.
 Clear independent memory (M) by pressing 0 Shift STO M
 Clear all memory values by pressing Shift CLR 2(Memory) = CA .
 Answer Memory
 The input values or the most recent calculation result will be automatically
stored into Answer memory whenever you press = , Shift = , M+ , Shift M-
, Shift STO memory, RCL memory. Answer memory can hold up to 18 digits.
 Recall and use the latest stored Answer memory by pressing Ans .
 Answer memory is not updated as an error operation had been performed.
 Answer memory contents can be maintained even if pressing CA , changing
the calculation mode, or turning off the calculator.

Fraction Calculations
The calculator supports Fraction calculation and the conversions between
Fraction, Decimal point, Mixed fraction and Improper fraction.
 Specify the fraction calculation result display format by either mixed fraction
( ) or improper fraction (
■
) in set-up menu.
 At the default setting, fractions are displayed as improper fractions (
■
).
 Mixed Fraction display result only available after setting the ( ) in the setup
menu.

 Press FD to switch a calculation result between fraction and decimal format.
 Press shift a b/c d/c to switch a calculation result between improper fraction
and mixed fraction format.
 Result will be displayed in decimal format automatically whenever the total digit
of a fractional value (integer + numerator + denominator + separator marks)
exceeds 10.
 If a fraction calculation is mixed with decimal value, the result will be displayed
by decimal format.

Replay & Multi-statements
 Replay Memory Function
 Replay memory is only available in COMP mode.
 After the calculation is executed，the calculation input and result will be stored
in the replay memory automatically.
 Pressing  (or  ) can replay the performed calculation input and result
history.
 After obtaining the calculation result on the display，press  or  to edit the
input expression of that result.
 lf the ► indicator is on the right side of a calculation result display，you need to
press CA and then  or  to scroll the calculation.
 Replay memory is cleared when you
(1). Initialize calculator setting by Shift CLR 3 = CA .
(2). Change from one calculation mode or display mode to other
(3). Press ON key.
(4). Press Shift OFF to power off machine.
 Multi-statements Function
 Use a colon : to put two or more calculations input together.
 The first executed statement will have “Disp” indicator；and the
“Disp”icon will disappeared after the last statement is being executed.
