In mathematics, the Fibonacci sequence is a sequence in which each number is the sum of the two preceding ones. Numbers that are part of the Fibonacci sequence are known as Fibonacci numbers, commonly denoted Fn . Many writers begin the sequence with 0 and 1, although some authors start it from 1 and 1 [1][2] and some (as did Fibonacci) from 1 ...
Glossary of mathematical symbols. A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various ...
The sum of the digits must be divisible by 9. [2] [4] [5] 2,880: 2 + 8 + 8 + 0 = 18: 1 + 8 = 9. Subtracting 8 times the last digit from the rest gives a multiple of 9. (Works because 81 is divisible by 9) 2,880: 288 − 0 x 8 = 288 − 0 = 288 = 9 x 32 10: The last digit is 0. [3] 130: the ones digit is 0. It is divisible by 2 and by 5
The Type 95 / QBZ-95 (Chinese: 轻武器,步枪,自动, 1995; pinyin: Qīng wǔqì, Bùqiāng, Zìdòng, 1995; lit. 'Light weapon, Rifle, Automatic, 1995') 5.8 mm caliber assault rifle, firing the 5.8×42mm / DBP87 or the improved DBP95, is now the standard-issue weapon in the PLA. The DBP87 service round was quickly supplemented in 1988 by the ...
For example, when d=4, the hash table for two occurrences of d would contain the key-value pair 8 and 4+4, and the one for three occurrences, the key-value pair 2 and (4+4)/4 (strings shown in bold). The task is then reduced to recursively computing these hash tables for increasing n , starting from n=1 and continuing up to e.g. n=4.
In mathematics, factorization (or factorisation, see English spelling differences) or factoring consists of writing a number or another mathematical object as a product of several factors, usually smaller or simpler objects of the same kind. For example, 3 × 5 is an integer factorization of 15, and (x – 2) (x + 2) is a polynomial ...

The three-by-five 三五判 (3×5 or 3/5), where the final size at 32K is slightly less than 3 by 5 sun, often given as 84 × 148 mm which would be c. 2.8 × 4.9 sun. The 4/6 standard has given rise to newer metric book-size standards, including:
