Random Numbers
A pseudo-random number with three significant digits can be
generated by pressing @`=. To generate the next
random number, press =.
Angular Unit Conversions
Each time @g are pressed, the angular unit changes
in sequence.
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 be-
come complicated, or when using the answer of previous
calculation to another operations.
Press NO to clear the independent memory (“M” sym-
bol will disappear).
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 automati-
cally be stored in the last answer memory.
@? : Recalls the value stored in last answer memory.

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.

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.
• Up to 10 key strokes, including “¬ ” and “
/
”, can be used
to enter a fraction.

Calculating the Greatest Common Factor (G.C.F.)
or Least Common Multiple (L.C.M.)
To calculate the G.C.F. or the L.C.M., the procedures are as
follows:
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.

Calculating with Fractions
Fractions can be incorporated into an arithmetic calculation.
“SIMP” symbol will appear with a calculation result if the
answer can be further simplified. Refer to the following sec-
tion of this manual for details.
