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.

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):
