BASIC DEFINITIONS

The Keys

To keep your calculator as compact as possible, some keys have more than one function. You can change the function of a key by pressing another key first, or by setting the calculator in a certain mode.

The following pages give you more detailed explanation of each key’s use and function.

2ndF

[SHIFT] Second Function Select Key

Some keys have a second function inscribed above them (for example, 1/x is above x2). To perform this second function, press [SHIFT]. «2F» appears in the display. Then press the key.

Example: To calculate the reciprocal of 5, press [5] [SHIFT] [1/x]. The display shows 0.2. In this manual, we refer to the key by the desired function. So, the example would be shown as [5] [SHIFT] [1/x].

General Keys

[0] — [9] [ • ] Data Entry Keys

Press these keys in their logical sequence to enter numbers.

[+], [−], [x], [ ], [=] Basic Calculation Keys

Press these keys in their logical sequence for addition, subtraction, multiplication, division, and to display answers.

[ON/C] Power ON/Clear Key

Press [ON/C] to turn on the calculator and to clear everything except the contents of the memory, constant memory (Ka, Kb), and program memory. It also overrides the auto power-off function.

[CE] Clear Entry Key

Press [CE] to erase incorrect entries.

[+/−] Sign Change Key

Press [+/−] to change the displayed number from positive to negative or from negative to positive. If you press [+/−] after pressing [EXP], the sign of the exponent changes.

Memory Keys

[MR] Memory Recall Key

Press [MR] to display the contents of the memory.

[XÆM] Memory Store Key

Press [XÆM] to store the displayed value into memory. Any previous value in memory is automatically erased.

[M+] Memory Plus Key

Press [M+] to total the current calculation and add the result to the value already in memory.

—E2-

[SHIFT] [KaxÆk], [SHIFT] [KbxÆk] Constant (Ka, Kb) Memory Store

Key

Press to enter the displayed value into constant memory Ka or Kb.

[KaxÆk], [KbxÆk] Constant (Ka, Kb) Memory Recall Key

Press to display the contents of a constant memory.

Notes:

•Constant memories Ka and Kb can have a value of 0.

•If you press [KaxÆk] or [KbxÆk] after entering a number or making a calculation, the displayed value is multiplied by the value in Ka or Kb.

Special Keys

[ ( ], [ ) ] Parenthesis Keys

This calculator uses true algebraic logic. It performs calculations using the following priority:

1)Functions

2)Calculations in parenthesis

3)Power and root calculations

4)Multiplication and division

5)Addition and subtraction

To change this order, enclose the expressions that must be calculated first within [ ( ] and [ ) ]. In a single expression, you can use a maximum of 42 nested parentheses at 6 levels (nesting of up to 7 parentheses in one level).

For example, if you press [−] 6 [x2] [=], the calculator gives a result of

−36. This might seem incorrect at first, since the square of a negative number is always positive. However, if you refer to the above priority sequence, you see that the power ([x2]) has a higher priority than the minus ([−]). So the calculator sees the entry as “the negative of six squared.” To make the calculator perform “negative six, squared” enter [ ( ] [−] 6 [ ) ] [x2] [=]. This forces the calculator to resolve the [−] 6 and then square the result.

[EXP] Exponent Key

To enter a number in scientific notation, first enter the numbers for the mantissa, press [EXP], and then enter the numbers for the exponent.

[SHIFT] [ π ] Key

Press [SHIFT] [ π ] to display the value of π, which is the ratio of a circle’s circumference to its diameter (approximately 3.141592654).

[SHIFT] [Æo’ ”], [SHIFT] [o’ ”Æ] Sexagesimal notation/decimal notation conversion Keys

To change from sexagesimal (base 60) notation (degree, minute, second) to decimal notation (degree) press [SHIFT] [o’ ”Æ]. To change

from decimal notation to sexagesimal notation, enter the number in decimal form and then press [SHIFT] [Æo’ ”] .

—E3-

[SHIFT] [X↔Y] Register Exchange Key

Press [SHIFT] [X↔Y] to exchange the displayed value (X−register) with the contents of the working register (Y−register).

[SHIFT] [FIX] Decimal Point Set Key

Use to set the number of digits displayed after the decimal point in either final or intermediate results. The calculator continues to use its full range for internal calculations, and only rounds the number in the display.

[SHIFT] [FIX] [0] — [6]

Sets the number of digits to be displayed to the right of decimal point.

[SHIFT] [FIX] [7], [8], [9], [ • ]

Selects floating point format.

Note: [SHIFT] [FIX] is inactive immediately after and during numerical input.

[DRG] Pressing this key will change the mode of angle unit sequentially Æ DEG Æ RAD ÆGRAD and display it on LCD.

[OFF] Power off key

Function Keys

[sin], [cos], [tan] Sine, Cosine, Tangent Keys

Calculate the trigonometric functions of the displayed value.

[SHIFT] [sin−1], [SHIFT] [cos−1], [SHIFT] [tan−1]

Arc Sine, Arc Cosine, Arc Tangent Keys

Calculate the inverse trigonometric functions of the displayed value.

[SHIFT] [HYP] [sin], [SHIFT] [HYP] [cos], [SHIFT] [HYP] [tan] Hyperbolic Keys
