SCIENTIFIC CALCULATIONS
• Select the normal mode.
• In each example, press N to clear the display before
performing the calculation.
1 ÷ 3 =
[Floating point] N 1 / 3 = 0.333333333
→ [Fixed decimal point] @fl 0.333333333
[TAB set to 2] @i 2 0.33

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

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.
245+60= N 245 + 60 = 305.
12+60= N 212 + 60 = 72.
150–20= 150 - 20 = 130.
250–20= 250 - 20 = 230.
200÷4= 200 / 4 = 50.
180÷4= 180 / 4 = 45.
15×3= 15 * 03 = 45.
15×10= 15 - 10 = 150.
Functions
• For each example, press N to clear the display.
• The results of inverse trigonometric functions are displayed
within the following ranges:
Priority Levels in Calculation
