Luhn algorithm. The Luhn algorithm or Luhn formula, also known as the " modulus 10" or "mod 10" algorithm, named after its creator, IBM scientist Hans Peter Luhn, is a simple check digit formula used to validate a variety of identification numbers. It is described in US patent 2950048A, granted on 23 August 1960. [ 1]
Modular multiplicative inverse. In mathematics, particularly in the area of arithmetic, a modular multiplicative inverse of an integer a is an integer x such that the product ax is congruent to 1 with respect to the modulus m. [1] In the standard notation of modular arithmetic this congruence is written as.
Battle of Dien Bien Phu. / 21.38694°N 103.01556°E / 21.38694; 103.01556. The Battle of Điện Biên Phủ was a climactic confrontation of the First Indochina War that took place between 13 March and 7 May 1954.

The Forward Air Controller (FAC) fulfilled many duties during the Second Indochina War.In addition to the usual close air support strike missions to aid South Vietnamese ground forces in their struggle against insurgents backed by the Democratic Republic of Vietnam, he might direct combat search and rescue operations or air interdiction strikes on the Ho Chi Minh Trail.

Adding 4 hours to 9 o'clock gives 1 o'clock, since 13 is congruent to 1 modulo 12. In mathematics, modular arithmetic is a system of arithmetic for integers, where numbers "wrap around" when reaching a certain value, called the modulus. The modern approach to modular arithmetic was developed by Carl Friedrich Gauss in his book Disquisitiones ...
Tiến lên ( Vietnamese: tiến lên, tiến: advance; lên: to go up, up; literally: "go forward"; also Romanized Tien Len) is a shedding -type card game originating in Vietnam. [ 1] It may be considered Vietnam's national card game, and is also played in the United States, sometimes under the names Viet Cong, [ 2] VC, [ 2] Thirteen, [ 2 ...
In mathematics, the result of the modulo operation is an equivalence class, and any member of the class may be chosen as representative; however, the usual representative is the least positive residue, the smallest non-negative integer that belongs to that class (i.e., the remainder of the Euclidean division ).
