The Rhind Mathematical Papyrus, [1] [2] an ancient Egyptian mathematical work, includes a mathematical table for converting rational numbers of the form 2/n into Egyptian fractions (sums of distinct unit fractions), the form the Egyptians used to write fractional numbers. The text describes the representation of 50 rational numbers.
Frog Fractions 2 is a sequel to the free browser-based game Frog Fractions, which was developed by independent game studio Twinbeard, founded by Jim Stormdancer.. Stormdancer used an extended alternate reality game (ARG) as part of the game's announcement and subsequent development, tying the release of the game to the success of the players' completing the AR
The game does not actually teach the player about fractions; [8] the player's score is given in fractions, but no knowledge of them is necessary to play. Its sequel, Frog Fractions 2, announced by a Kickstarter in 2014, was released in December 2016 after players successfully completed a multi-segmented alternative reality game assembled by ...
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.
6 1 2 1 1 −1 4 5 9. and would be written in modern notation as 6 1 / 4 , 1 1 / 5 , and 2 − 1 / 9 (i.e., 1 8 / 9 ). The horizontal fraction bar is first attested in the work of Al-Hassār (fl. 1200), [35] a Muslim mathematician from Fez, Morocco, who specialized in Islamic inheritance jurisprudence.
Pell's equation for n = 2 and six of its integer solutions. Pell's equation, also called the Pell–Fermat equation, is any Diophantine equation of the form =, where n is a given positive nonsquare integer, and integer solutions are sought for x and y.
790 = 2 × 5 × 79, sphenic number, nontotient, a Harshad number in bases 2, 7, 14 and 16, an aspiring number, [69] the aliquot sum of 1574. 791 = 7 × 113, centered tetrahedral number , sum of the first twenty-two primes, sum of seven consecutive primes (101 + 103 + 107 + 109 + 113 + 127 + 131)
[6] [7] [8] Oliver Heaviside introduced the practical use of fractional differential operators in electrical transmission line analysis circa 1890. [9] The theory and applications of fractional calculus expanded greatly over the 19th and 20th centuries, and numerous contributors have given different definitions for fractional derivatives and ...
