Calculating fractions
Fractions are displayed in a linear mode in the following way:
5˩12 is the notation of the fraction 5/12.
2˩5˩12 is the notation of the fraction 2 5/12.
Note: Values are automatically displayed in the decimal format if the total num-
ber of characters (number + numerator + denominator + separator characters)
exceeds 10.
To enter mixed fractions, press [a b/c] and enter the entire part of the fraction,
numerator and denominator. When entering an improper or proper fraction, first
enter the numerator and then the denominator after pressing [a/b].
If the algebraic fraction can be reduced, this is done after pressing [=]. The
initial result of the algebraic fraction is an improper fraction, i.e. the numerator
is greater than the denominator. Press [2ND][ab/c◄►d/c] to convert the
displayed value to a mixed fraction and vice versa. To convert a decimal number
into fraction and vice versa, press [F◄►D].
If both fractions and decimal numbers are used in mathematical operations,
decimal numbers are used for calculations.
Probability
The calculator enables you to calculate the following probability functions:
Calculation of possible r-element variations without repetition from
[nPr]
the overall number of n elements.
Calculation of possible r-element combinations without repetition
[nCr]
from the overall number of n elements.
Calculation of factorial of a positive integer "n", where n ≤ 69.
[x!]
Generating random numbers between 0 and 0.999.
Ran#
This function generates random integers in the defined interval
RanInt
(including limits). To generate a random number in the interval from
1 to 6, enter:
Other functions (√,
The calculator may also be used to calculate inversions, roots, general roots,
and powers.
Calculation of an absolute value of a number.
Abs
Calculation of a round value of numbers.
Round
Prime factorization – the expression of a natural number as a
FACT
product of powers of prime numbers. Before displaying factorization,
press [=] and then [2ND][FACT].
TABLE calculation mode (function table)
Function tables are used in the TABLE mode, press [MODE/SET UP][3]. This
mode enables you to define functions and their expression in the form of a
table. To display the function table:
