INTRODUCTION
Thank you for purchasing the SHARP Scientific Calculator
Model EL-530V. This calculator will help you understand mathematical concepts behind fraction calculation, such as simplification and reduction.
After reading this manual, store it in a convenient location for
future reference.
Operational Notes
• Do not carry the calculator around in your back pocket, as it
may break when you sit down. The display is made of glass
and is particularly fragile.
• Keep the calculator away from extreme heat such as on a
car dashboard or near a heater, and avoid exposing it to
excessively humid or dusty environments.
• Since this product is not waterproof, do not use it or store it
where fluids, for example water, can splash onto it. Raindrops, water spray, juice, coffee, steam, perspiration, etc.
will also cause malfunction.
• Clean with a soft, dry cloth. Do not use solvents or wet
cloth.
• Do not drop it or apply excessive force.
• Never dispose of batteries in a fire.
• Keep batteries out of the reach of children.
• This product, including accessories, may change due to
upgrading without prior notice.
SHARP will not be liable nor responsible for any incidental
or consequential economic or property damage caused by
misuse and/or malfunctions of this product and its peripherals, unless such liability is acknowledged by law.
♦ Press the RESET switch (on the back), with the tip of a ball-
point pen or similar object, only in the following cases.
Do
not use an object with a breakable or sharp tip. Note that
pressing the RESET switch erases all data stored in
memory.
• When using for the first time
• After replacing the batteries
• To clear all memory contents
• If an abnormal condition occurs and all keys are
inoperative.
If service should be required on this calculator, use only a
SHARP servicing dealer, SHARP approved service facility, or
SHARP repair service where available.
Hard Case
• All symbols will not be displayed simultaneously, as shown
above.
• Certain inactive symbols may appear visible when viewed
from a far off angle.

INITIAL SETUP
Mode Selection
Normal Mode:
Used to perform arithmetic operations and function calculations.
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
θ = sin-1x, θ = tan-1x θ = cos-1x
–90° ≤ θ ≤ 90° 0° ≤ θ ≤ 180°

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.

Chain Calculations
• This calculator allows the previous calculation result to be
used in the following calculation.
• The previous calculation result will not be recalled after
entering multiple instructions.
• In the case of utilizing postfix functions (¿ , sin, etc.), you
can perform a chain calculation even when the previous
calculation result is cleared by the use of the N or @
c keys.
Calculating the Highest Common Factor
(H.C.F.) or Lowest Common Multiple (L.C.M.)
To calculate the H.C.F. or the L.C.M., the procedures are as
follows:
What is the H.C.F.
N 24
24_
of 24 and 36?
@‹ 36

=
12.
What is the L.C.M.
N 15
15_
of 15 and 9?
@ˆ 9
15LCM9_
=
45.
• “Highest Common Factor” is synonymous with “Greatest
Common Factor”, “Lowest Common Multiple” is with “Least
Common Multiple”.
Calculating quotient and remainder
“: Calculates the quotient and remainder.
• Pressing “ cannot be followed by pressing a key for
another operation such as (+, –, ×, ÷), otherwise an error
will result.
• The calculator can display a quotient or remainder up to 5
digits in length, including the “–” sign. If numbers longer
than 5 digits are entered, normal division is performed.

FRACTION CALCULATIONS
Entering Fractions
• To enter fractions, use the following keys:
Ø : Places the symbol “
/
” between the numerator
and the denominator.
∞ : Separates the integer (whole number) part from
the fractional part of a mixed number.
Memory Calculations
This calculator has two memory allocations: independent
memory (M), and last answer memory (ANS). You will find
them especially useful when combinations of calculations become complicated, or when applying the answer of previous
calculation to another operations.
• Press NO to clear the independent memory (“M”
symbol will disappear).
• After pressing R to recall a value stored in the memory,
the value as displayed will be used in the calculation.
Independent memory (M)
O : Stores the result in the memory.
R : Recalls the value stored in the memory.
@; : Adds the result to the value in the memory.
Last answer memory (ANS)
When = is pressed, the calculation result will automatically be stored in the last answer memory.
@? : Recalls the value stored in the last answer
memory.
