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.
[+], [−

÷÷ ], [=] 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.
[XÆ

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.

Notes:
• Constant memories Ka and Kb can have a value of 0.
• If you press [Kax k

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

π π ] Key
Press [SHIFT] [ π

circle’s circumference to its diameter (approximately 3.141592654).

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’ ”] .
