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 ( num denom 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:
[nPr] Calculation of possible r-element variations without repetition from
the overall number of n elements.
[nCr] Calculation of possible r-element combinations without repetition
from the overall number of n elements.
[x!] Calculation of factorial of a positive integer “n“, where n ≤ 69.
Ran#
Generating random numbers between 0 and 0.999.
