* Temporary memories A-D, X and Y, statistical data, and last an-
swer memory.
Refer to the Memory Calculations section.
Editing the Equation
• Press < or > to move the cursor.
To return to the equation after getting an answer, press @
'.
• To delete a number, move the cursor to the number to be
deleted, then press d.
The number under the cursor will be deleted.
• To insert a number, move the cursor to the place immediately
after where the number is to be inserted, then enter the number.
Priority Levels in Calculation
This calculator performs operations according to the following pri-
ority:
Q
W Functions preceded by their argument (x
¿
E Y x x
,
R Implied multiplication of a memory value (2Y, etc.)
T Functions followed by their argument (sin, cos, etc.)
Y Implied multiplication of a function (2sin30, etc.)
U C , P
n r n r
I , ÷
O +, –

• If parentheses are used, parenthesized calculations have prec-
edence over any other calculations.
INITIAL SETUP
Mode Selection
Normal mode: m0
Used to perform arithmetic operations and function calculations.
The pointer "Æ" appears below "0: NORMAL".
Complex number mode: m1
Used to perform arithmetic operations with complex numbers.
The pointer "Æ" appears below "1: CPLX".
3-VLE mode : m2
Used to perform simultaneous linear equations with three unknowns.
The pointer "Æ" appears below "2: 3-VLE".
Statistic mode: m3
Used to perform statistical calculations.
The pointer "Æ" appears below "3: STAT".
When executing mode selection, temporary memories, statistical
data and last answer memory will be cleared even when reselecting
the same mode.
