Editing the Equation
Press or to move the cursor . You can also return to the equation after
getting an answer by pressing ( ) .See below for Multi-line playback
function.
lf you need to delete a number, move the cursor to the number you wish to
delete then press . The number under the cursor will be deleted.
lf you need to insert a number, move the cursor to the place immediately after
where you wish to insert the number then enter the number.
Multi-line Playback function
This calculator is equipped with a function to recall previous equations. Equations also
include calculation ending instructions such as "=" and a maximum of 142characters 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). ln addition, Can be
used to jump to the oldest equation.

,RESET, , , constant calculation, angle conversion / change,
coordinate conversion, numerical value storage to the temporary memories and
independent memory, and input/deletion of statistical data.

Priority Levels in Calculation
This calculator performs operations,according to the following priority:
Functions preceded by their argument (x-1, x2 n!, etc.)
Yx lmplied multiplication of a memory value (2Y, etc.) Functions followed
by their argument (sin, cos , ;etc.) implied multiplication of a function (2sin30,etc.)
and other calculation ending
instruction
lf parentheses are used,parenthesized calculations have precedence over any other
calculations.
Initial Setup
Mode selection
Normal mode:
Used to perform arithmetic operations and function calculations.
Single-variable statistics mode:
Used to perform 1-variable statistical calculations.
Two-variable statistic mode:
Used to perform 2-variable statistical calculations.
When executing mode selection, temporary memories, statistical data and last answer
memory will be cleared even when reselecting the same mode.
10
Selecting the Display Notation and Decimal Places
The calculator has four display notation systems for displaying calculation results. When
FIX, SCI, or ENG symbol is displayed, the number of decimal places can be set to any
value between 0 and 9. Displayed values will be reduced to the corresponding number
of digits.
100 000 ÷ 3 =
[Floating point]
[Fixed decimal point]
[TAB set to 2]
[Scientific notation]
[Engineering notation]
[Floating point]
If the value for floating point system does not fit in the following range, the calculator
will display the result using scientific notation system:
0.000000001 |x| 9999999999
Determination of the Angular Unit
In this calculator, the following three angular units can be specified.
11
Scientific Calculations
Press to select the normal mode.
In each example, press to clear the dislay.
If the FIX, SCI or ENG indicator is displayed, clear the indicator by pressing .
Arithmetic Operations / Constant Calculations
The closing parenthesis ) just before = or M+ may be omitted.
The addend becomes a constant. Subtraction and division are performed in the same
manner.
The multiplicand becomes a constant.
When performing calculations using constants, constants will be displayed as K.
12
Functions
Before starting calculations, specify the angular unit.
The results of inverse trigonometric functions are displayed within the following range:
13
14
Random Numbers
A pseudo-random number with three significant digits can be generated by pressing
. To generate the next random number, press = . You can perform this
function in the normal and statistics modes.
Random numbers use memory Y. Each random number is generated on the basis of the
value stored in memory Y (pseudo-random number series).
Angular Unit Conversions
Memory Calculations
This calculator has 6 temporary memories (A-D, X and Y),one independent memory (M)
and one last answer memory. Independent memory and temporary memories are only
available in the normal mode.
[Temporary memories (A-D, X and Y)]
A stored value can be recalled as a value or variable for the use in equations. In case you
store an infinite decimal in the memory, recall it as a variable to obtain accurate
answers.
Example:
(0.3333……..Is stored to Y)
15
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.
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 numbers................. Y memory
r0, xy.............................. X memory, Y memory
Temporary memories and last answer memory are cleared even when the same mode
is reselected.
* Entry of the multiplication procedure is omitted between " " and a variable.
16
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.
Fraction Calculations
A decimal number, variable, or exponent cannot be entered as a fraction.
In all cases, a total of up to 10 digits including integer, numerator, denominator
and the symbol ( ) can be entered.
If the number of digits to be displayed is greater than 10, the number is
converted to and displayed as a decimal number.
17
Time, Decimal and Sexagesimal Calculations
Conversion between decimal and sexagesimal numbers can be performed. In addition,
the four basic arithmetic operations and memory calculations can be carried out using
the sexagesimal system.
Coordinate Conversions
Before performing a calculation, select the angular unit.
Rectangular coord
Polar coord
The calculation result is automatically stored in memories X and Y.
Value of r or x: X memory
Value of θ or y: Y memory
18
Modify Function
In this calculator, all calculation results are internally obtained in scientific notation with
up to 12 digits for the mantissa. However, since calculation results are displayed in the
form designated by the display notation and the number of decimal places indicated,
the internal calculation result may differ from that shown in the display. By using the
modify function, the internal value is converted to match that of the display, so that the
displayed value can be used without change in subsequent operations.
19
Statistical Calculations
Press to select single-variable statics mode and to
select two-variable statistics mode. The following statistics can be obtained for each
statistical calculation (refer to the table below):
Single-variable statistical calculation: Statistics of 1 Linear regression calculation:
