2 = 3 3 − 5 2 10 = 13 3 − 3 7 18 = 19 2 − 7 3 = 3 5 − 15 2. It had been conjectured that 6 cannot be so represented, and Golomb conjectured that there are infinitely many integers which cannot be represented as a difference between two powerful numbers. However, Narkiewicz showed that 6 can be so represented in infinitely many ways such as
In 2012, an article published in the Journal of MultiDisciplinary Evaluation [7] posed the necessity of a Scriven number. Similar to an Erdős number, a Scriven number describes a person's degree of separation from Dr. Scriven through published collaborations directly with him or with others who have collaborated with him. Michael Scriven held ...
In a vigesimal place system, twenty individual numerals (or digit symbols) are used, ten more than in the decimal system. One modern method of finding the extra needed symbols is to write ten as the letter A, or A 20, where the 20 means base 20, to write nineteen as J 20, and the numbers between with the corresponding letters of the alphabet.
9 1/2; 9 + 1 ⁄ 2 9 + 1 / 2 Numbers with a decimal point may be read as a cardinal number, then "and", then another cardinal number followed by an indication of the significance of the second cardinal number (mainly U.S.); or as a cardinal number, followed by "point", and then by the digits of the fractional part. The indication of ...
A Belphegor number is a palindromic number in the form of () ().The sequence of the first four Belphegor numbers is: ,,,, … Dubner noticed that 16661 is a prime number. By adding zeroes directly on both sides of the 666, Dubner found more palindromic prime numbers, including the Belphegor prime, which is second in the sequence.
In elementary number theory, a highly powerful number is a positive integer that satisfies a property introduced by the Indo-Canadian mathematician Mathukumalli V. Subbarao. [1] The set of highly powerful numbers is a proper subset of the set of powerful numbers. Define prodex(1) = 1.
There is another phrase known in Romanian that will help to memorize the number by eight decimal places: Așa e bine a scrie renumitul și utilul număr. — "This is the way to write the renowned and useful number." Another alternative for 15 decimal places: Ion a luat o carte, biografie, în latina veche.
