Priority Levels in Calculation
This calculator performs operations according to the following
priority:
1 Functions expressed with numerical data placed before
(such as x
2
, x
3
)
2 y
x
x
,
¿
y
3 π
4 Functions expressed with numerical data placed after (such
as sin, cos)
5 Multiplications with the sign "×" omitted from the front of a
function (such as 3cos20)
6 ×, ÷
7 +, –
8 Operations end commands (such as =, M+, %, DATA, CD)
•
A parenthesized calculation section has precedence over
other sections of the calculation.
INITIAL SETUP
Mode Selection
Normal Mode:
Used to perform arithmetic operations and function calcula-
tions.
Statistical Mode:
Used to perform statistical operations. To enter statistical
mode, press @". ' appears on the display to
indicate that the statistical mode is selected. To return to
normal mode, press @" with ' on the display.
' disappears as the calculator returns to normal mode.
• The mode will remain selected when the calculator is turned
off.
• When executing mode selection, last answer memory will
be cleared.
Selecting the Display Notation and Decimal
Places
This calculator has two display notation systems for displaying
calculation results: floating point system and fixed decimal
point system.
When the fixed decimal point system is selected, the number
of decimal places can be set to any value between 0 and 9.
The last decimal digit will be rounded off.
• Use @fl to switch to the fixed decimal point system,
press @i, then enter a value between 0 and 9 to set
the decimal placement.
• The number will be displayed in scientific notation if the
calculation results for floating point system does not fit in
the following range:
0.000000001 ≤ | x | ≤ 9999999999
1 ÷ 3 =

Constant Calculations
• In constant calculations, the addend becomes a constant.
Subtraction and division are performed in the same manner.
For multiplication, the multiplicand becomes a constant.
• After performing calculations using constants, on pressing
<(>) to edit an equation, the constants will be
displayed as K.
