Multi-line Playback function
This calculator is equipped with a function to recall previous equations in
the normal mode. Equations also include calculation ending instructions
such as “=” and a maximum of 142 characters can be stored in memory.
When the memory is full, stored equations are deleted in the order of the
oldest first. Pressing [ will display the previous equation and the
answer. Further pressing [ will display preceding equations (after
returning to the previous equation, press ] to view equations in order).
In addition, @[ can be used to jump to the oldest equation.
• To edit an equation after recalling it, press > (<).
• To edit the displayed equation, press > (<) immediately after
obtaining a calculation answer.
• The multi-line memory is cleared by the following operations:
@c, @F (including the Automatic Power Off feature),
mode change, memory clear (@∏), RESET, @`, K
(R) ?, constant calculation, chain calculation, angle unit
conversion, coordinate conversion, N-base conversion, numerical value
storage to the temporary memories and independent memory.

INITIAL SET UP
Mode Selection
Normal mode (NORMAL): m0
Used to perform arithmetic operations and function calculations.
Statistics mode (STAT): m1
Used to perform statistical calculations.
Equation mode (EQN): m2
Used to perform equation calculations.
When executing mode selection, temporary memories, statistical variables,
statistical data and last answer memory will be cleared even when reselecting
the same mode.
SET UP menu (FIX, SCI, ENG, NORM1, NORM2)
Press ” to display the SET UP menu.
•A menu item can be selected by:
• moving the flashing cursor by using ><, then press ®
(= key), or
• pressing the number key corresponding to the menu item number.
• If
or is displayed on the screen, press [ or ] to view the
previous/next menu screen.
• Press ª to exit the SET UP menu.
[Selecting the Display Notation and Decimal Places]
The calculator has four display notation systems (Floating point, Fixed
decimal point, Scientific notation and Engineering notation) for displaying
calculation results.
• If ”0 (FIX) or ”2 (ENG) is pressed, ‘TAB(0-9)?’ will
be displayed and the number of decimal places (TAB) can be set to any
value between 0 and 9.
• If ”1 (SCI) is pressed, ‘SIG(0-9)?’ will be displayed and the
number of significant digits (SIG) can be set to any value between 0 and
9. Entering 0 will set a 10-digit display.
• If a floating point number does not fit in the specified range, the calculator
will display the result using the scientific notation (exponential notation)
system. See ‘Setting the Floating Point Numbers System in Scientific
Notation’ for details.
[Setting the Floating Point Numbers System in Scientific Notation]
The calculator has two settings for displaying a floating point number:
NORM1 (default setting) and NORM2. In each display setting, a number is
automatically displayed in scientific notation outside a preset range:
• NORM1: 0.000000001 ≤ x ≤ 9999999999
• NORM2: 0.01 ≤ x ≤ 9999999999

Determination of the Angular Unit
In this calculator, the following three angular units (degrees, radians, and
grads) can be specified.
SCIENTIFIC CALCULATIONS
• Press m0 to select the normal mode.
• In each example, press ª to clear the display. And if the FIX, SCI,
or ENG indicator is displayed, clear the indicator by selecting ‘NORM1’
from the SET UP menu.
Arithmetic Operations
• The closing parenthesis ) just before = or ; may be
omitted.
Constant Calculations
• In constant calculations, the addend becomes a constant. Subtraction
and division are performed in the same manner. For multiplication, the
multiplicand becomes a constant.
• When performing calculations using constants, constants will be
displayed as K.
Functions
• Refer to the calculation examples of each function.
• Before starting calculations, specify the angular unit.
Random Function
The Random function has four settings for use in the normal or statistics
mode. (This function cannot be selected while using the N-Base function.)
Press ª to exit.
• The generated pseudo-random number series is stored in memory Y.
Each random number is based on a number series.
[Random Numbers]
A pseudo-random number, with three significant digits from 0 up to 0.999,
can be generated by pressing @`0®. To generate the
next random number, press ®.
[Random Dice]
To simulate a die-rolling, a random integer between 1 and 6 can be
generated by pressing @`1®. To generate the next
random dice number, press ®.
[Random Coin]
To simulate a coin flip, 0 (head) or 1 (tail) can be randomly generated by
pressing @`2®. To generate the next random coin
number, press ®.
[Random Integer]
An integer between 0 and 99 can be generated randomly by pressing
@`3®. To generate the next random integer number,
press ®.
Angular Unit Conversions
Each time @g are pressed, the angular unit changes in sequence.
Memory Calculations
This calculator has 8 temporary memories (A-F, X and Y), one independent
memory (M) and one last answer memory (ANS). The independent
memory and temporary memories are only available in the normal mode.
[Temporary memories (A-F, X and Y)]
Press O and a corresponding variable key to store a value in memory.
Press R and a corresponding variable key to recall a value from the
memory.
To place a variable in an equation, press K, followed by a desired
variable key.
[Independent memory (M)]
In addition to all the features of temporary memories, a value can be
added to or subtracted from an existing memory value.
Press ªOM to clear the independent memory (M).
[Last answer memory (ANS)]
The calculation result obtained by pressing = or any other calculation
ending instruction is automatically stored in the last answer memory.
Note:
• Calculation results from the functions indicated below are automatically
stored in memories X or Y. For this reason, when using these functions,
be careful with the use of memories X and Y.
• Random function ...................... Y memory
• →rθ, →xy ................................ X memory (r or x),
Y memory (θ or y)
• Temporary memories and last answer memory are cleared even when
the same mode is reselected.
• Use of R or K will recall the value stored in memory using up
to 14 digits.
Chain Calculations
• This calculator allows the previous calculation result to be used in the
following calculation.
• The previous calculation result will not be recalled after entering multiple
instructions.
• In the case of utilizing postfix functions (
¿
, sin, etc.), you can
perform a chain calculation even when the previous calculation result
is cleared by the use of the ª or @c keys.
