If only numbers with unique non-zero digits are considered, a three-digit number in base ten can have a digit-sum ranging from 6 = 1+2+3 to 24 = 7+8+9. If these potential digit-sums are used in the formula 2 x digit-sum x 11, the digit-sum of the result will determine whether or not the result is an Osiris number. 1. 2 x 6 x 11 = 132. 2.
Simplification is the process of replacing a mathematical expression by an equivalent one that is simpler (usually shorter), according to a well-founded ordering. Examples include:
Even though 1829 braille had a simple ciphered-positional system copied from Western numerals with a separate symbol for each digit, early experience with students forced its designer Louis Braille to simplify the system, bringing the number of available patterns (symbols) from 125 down to 63, so he had to repurpose a supplementary symbol to ...
Multiplication table from 1 to 10 drawn to scale with the upper-right half labeled with prime factorisations. In mathematics, a multiplication table (sometimes, less formally, a times table) is a mathematical table used to define a multiplication operation for an algebraic system.
In a 1966 paper he proved what is now called Chen's theorem: every sufficiently large even number can be written as the sum of a prime and a semiprime (the product of two primes) – e.g., 100 = 23 + 7·11. [1] Despite being persecuted during the Cultural Revolution, he expanded his proof in the 1970s. [2]
63 is a Mersenne number of the form with an of , [5] however this does not yield a Mersenne prime, as 63 is the forty-fourth composite number. [6] It is the only number in the Mersenne sequence whose prime factors are each factors of at least one previous element of the sequence ( 3 and 7 , respectively the first and second Mersenne primes).

The Working Group presented HTTP/2 to the Internet Engineering Steering Group (IESG) for consideration as a Proposed Standard in December 2014, [6] [7] and IESG approved it to publish as Proposed Standard on February 17, 2015 (and was updated in February 2020 in regard to TLS 1.3 and again in June 2022). The initial HTTP/2 specification was ...
