The handbook was originally published in 1928 by the Chemical Rubber Company (now CRC Press) as a supplement (Mathematical Tables) to the CRC Handbook of Chemistry and Physics. Beginning with the 10th edition (1956), it was published as CRC Standard Mathematical Tables and kept this title up to the 29th edition (1991).
The National Stock Number was the same number as the FSN, plus the two-digit National Codification Bureau (NCB) "Country Code" added between the FSCG code and the item code. The US government added the code numbers "00" in the place of the NCB digits to all FSN numbers to create compliant American NSN numbers.
A list of articles about numbers (not about numerals). Topics include powers of ten, notable integers, prime and cardinal numbers, and the myriad system.
The tables below list all of the divisors of the numbers 1 to 1000. A divisor of an integer n is an integer m , for which n / m is again an integer (which is necessarily also a divisor of n ). For example, 3 is a divisor of 21, since 21/7 = 3 (and therefore 7 is also a divisor of 21).
The NATO Stock Number or National Stock Number (NSN) is a 13-digit alphanumeric code consisting of a Group of Supply, a Class of Supply and the unique NIIN to designate unique items of supply grouped by their relative catalog category. The first four digits are the NATO Supply Classification (NSC) or Federal Supply Class (FSC) code.
In general, the number to be represented was broken down into simple multiples (1 to 9) of powers of ten — units, tens, hundred, thousands, etc.. Then these parts would be written down in sequence, from largest to smallest value. For example: 49 = 40 + 9 = ΔΔΔΔ + ΠΙΙΙΙ = ΔΔΔΔΠΙΙΙΙ; 2001 = 2000 + 1 = ΧΧ + I = ΧΧΙ
A factorial x! is the product of all numbers from 1 to x. The first: 1, 2, 6, 24, 120, 720, 5040, 40320, 362880, 3628800, 39916800, 479001600 (sequence A000142 in the OEIS). 0! = 1 is sometimes included. A k-smooth number (for a natural number k) has its prime factors ≤ k (so it is also j-smooth for any j > k).
