(During actual use not all symbols are displayed at
the same time.)
If the value of mantissa does not fit within the range
±0.000000001- ±9999999999, the display changes to
scientific notation. The display mode can be changed
according to the purpose of the calculation.
2ndF : Appears when 2ndF is pressed, indicating
that the functions that print are ed in the same colour as
2ndF are enabled.
HYP : Indicates that hyp has been pressed and
the hyperbolic functions are enabled. 2ndF hyp If arc are
pressed, the symbols “2ndF HYP” appear, indicating that
inverse hyperbolic functions are enabled.
DEG/RAD/GRAD: Indicates angular units and
changes each time is pressed. The default setting DRG
is DEG.

HEX : Indicates that 2ndF has been →HEX
pressed. Hexadecimal system mode is selected.
CPLX : Indicates that 2ndF CPLX has been
pressed. Complex number mode is selected.
STAT : Indicates that 2ndF has been STAT
pressed. Statistics mode is selected.

Before Using the Calculator
Key Notation Used in This Manual
In this manual, key operations are described as
follows:
TO specify A (HEX) : A
TO sp 2ndF ecify π : π
TO specify Exp : Exp
Functions that are printed in the same colour as
2ndF above the key require 2ndF to be pressed first
before the key. Numbers keys do not have second
function regardless of pressing 2ndF first, but as ordinary
numbers.

3. Priority Levels in Calculation
Operations are executed according to the following
hierarchy:
1.Function calculations such as sin and %
2.Calculations in parenthesis
3. Powers and roots
4.×, ÷
5. +,-

※ In the example above, notice that the
multiplication is performed first. Performing 2×2+8 should
give the same result as the preceding one.
4. Parenthesis
a) Using Parenthesis
The parenthesis allow changes to be made to the
priorities of the operators. For example, to calculate 3×(8-
5).
If you leave out the parenthesis, the multiplication
between 3 and 8 is performed first, then the subtraction
of the result with 5 is made.
The presence of the parenthesis allows the
subtraction of 8 and 5 to be made first and the
multiplication of this result with 3.
