  2. Rational data type - Wikipedia

    en.wikipedia.org/wiki/Rational_data_type

    Python: The standard library includes a Fraction class in the module fractions. [6] Ruby: native support using special syntax. Smalltalk represents rational numbers using a Fraction class in the form p/q where p and q are arbitrary size integers. Applying the arithmetic operations *, +, -, /, to fractions returns a reduced fraction. With ...

  3. Greedy algorithm for Egyptian fractions - Wikipedia

    en.wikipedia.org/wiki/Greedy_algorithm_for...

    The simplest fraction ⁠ 3 / y ⁠ with a three-term expansion is ⁠ 3 / 7 ⁠. A fraction ⁠ 4 / y ⁠ requires four terms in its greedy expansion if and only if y ≡ 1 or 17 (mod 24), for then the numerator −y mod x of the remaining fraction is 3 and the denominator is 1 (mod 6). The simplest fraction ⁠ 4 / y ⁠ with a four-term ...

    en.wikipedia.org/wiki/Farey_sequence

    In mathematics, the Farey sequence of order n is the sequence of completely reduced fractions, either between 0 and 1, or without this restriction, [a] which when in lowest terms have denominators less than or equal to n, arranged in order of increasing size.

    The 2022 Ironman World Championship was split with a men's and women's race and the Women's Championship on October 6 followed by the Men's Championship two days later. Also from 2022, Vietnam's automobile maker VinFast was the first ever naming rights partner for 2022 Ironman World Championship and 2023 Ironman 70.3 World Championship. [6]

  6. Erdős–Graham problem - Wikipedia

    en.wikipedia.org/wiki/Erdős–Graham_problem

    In combinatorial number theory, the Erdős–Graham problem is the problem of proving that, if the set {,,, …} of integers greater than one is partitioned into finitely many subsets, then one of the subsets can be used to form an Egyptian fraction representation of unity.

  7. Egyptian fraction - Wikipedia

    en.wikipedia.org/wiki/Egyptian_fraction

    The Rhind Mathematical Papyrus. An Egyptian fraction is a finite sum of distinct unit fractions, such as + +. That is, each fraction in the expression has a numerator equal to 1 and a denominator that is a positive integer, and all the denominators differ from each other.

  8. Partition function (number theory) - Wikipedia

    en.wikipedia.org/wiki/Partition_function_(number...

    For a positive integer n, p(n) is the number of distinct ways of representing n as a sum of positive integers. For the purposes of this definition, the order of the terms in the sum is irrelevant: two sums with the same terms in a different order are not considered to be distinct.
