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.

When you press the key ( , the small sign”(
)”appears on the display above the digits, means that
parenthesis has been opened. This sign disappears
when the parenthesis is closed
b) Levels of the Parenthesis
There are 4 levels of parenthesis. This means that
you cannot have more than 4 operations pending.
- Try the calculation 2+(3+(4+(5+(6+7))) .
To carry out this calculation, simply press the keys in
the order they appear in writing. When you press the fifth
sig n “+”, the error message will display.
c) Closing Parenthesis
Instead of closing the nested parenthesis and
pressing the key = , simply press the key = and
calculator will give the correct result. For example ,in the
calculation of 5×(4+9),you type 5 × ( 4 + 9 =
instead of 5 × ( 4 + 9 ) = you will get the
correct answer..
5. Selecting the Display Notation and Decimal
Places
When calculation result is displayed in the floating
point system, pressing F displays the result i↔E n
the scientific notation. Pressing once more F↔E
displays the result again in the floating point system.
Pressing 2ndF TAB and any value between 0 and
9 specifies the number of decimal places in the
calculation result. To clear the setting of decimal
places, press 2ndF TAB · .

6. Angle Units : Degree, Radian and Gradient
Before any trigonometric calculation, make sure the
angle unit with which you use to make the calculation
conforms with the one that the calculator will use. The
angle unit is indicated above the display of the digits.
This unit is marked by R “DEG”for degree, “AD”for
radian and GRAD “ ” for gradient. Each press the key
DRG will alternate between these units.
You may also want to convert an angle into another
unit. The function that enables you to do that is the
second function of the key , marked . DRG DRG►
We shall try to convert 180° in radian. First, make
sure that the angle unit display is the degree(symbol
DEG):Press the number 180,then press the key 2ndF
and , The calculator will display the value of DRG
“π”(3.141592654),value of 180°in radian.
7. Addition, Multiplication, Subtraction and
Division

b) Multiplication, Division and Subtraction of Two
Numbers
These calculations are performed in the same
manner as the addition.
8. Constant Calculations
In the constant calculations, the addend becomes a
constant. Subtraction and division are performed in the
same manner. For multiplication, the multiplicand
becomes a constant.

9. Trigonometric Functions
The functions cosine, sine and tangent are accessed
respectively by the keys cos sin , and tan . ,
To calculate, for example, the cosine of an angle,
enter the value of the angle, and press the key cos .
Example: The calculation cosine of 60о(make sure
the calculator is In degree mode.)

10. Logarithmic and Exponential Functions
The natural logarithm and common logarithm
functions are accessed respectively with the keys ln
and log .
The second function of the key is the inverse ln
function of the natural logarithm, or natural antilogarithm
ex .
The second function of the key log is the inverse
function of the common logarithm, or common
antilogarithm 10x .
11. The functions Square, Root, Power and
Reciprocal
The calculation square( x2
), square root( x), cubic √
root(second function of the key √x ,marked by
3x
), and
reciprocal(second function of the key x2 ,marked by 1/x)
is the same as the one explained above for trigonometric
functions. The value, ”x” must be enter first before the
chosen function. For the universal power(key yx
), and
root (second function of the key yx ,marked by ), enter
the value for “y” first then the value for “x”.
