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:
The Geschützwagen Tiger (G.W. Tiger) was a German self-propelled gun carrier of World War II that never saw service.. It would have been able to carry either the 17cm Kanone K72 (Sf) or the short barrelled 21cm Mörser 18/1 which had the same mounting; with the former it would be known as Grille 17, the latter Grille 21.
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 PM-63 RAK (often incorrectly referred to as Ręczny Automat Komandosów—"commandos' hand-held automatic"; the name itself means cancer or crayfish in Polish) is a Polish 9×18mm submachine gun, designed by Piotr Wilniewczyc in cooperation with Tadeusz Bednarski, Grzegorz Czubak and Marian Wakalski.
