Next, it checks for if the char is an A, and converts it to AM. k Because the amount of daylight a location receives varies over the course of a year, the length of nighttime versus daylight hours grew and shrank in proportion to each other as the seasons progressed. The modern approach to modular arithmetic was developed by Carl Friedrich Gauss in his book Disquisitiones Arithmeticae, published in 1801. In particular, if p is a prime number, then a is coprime with p for every a such that 0 < a < p; thus a multiplicative inverse exists for all a that is not congruent to zero modulo p. Some of the more advanced properties of congruence relations are the following: The congruence relation is an equivalence relation. The Latin abbreviations a.m. and p.m. (often written "am" and "pm", "AM" and "PM", or "A.M." and "P.M.") are used in English and Spanish.

The 12-hour time convention is common in several English-speaking nations and former British colonies, as well as a few other countries. Each residue class modulo n may be represented by any one of its members, although we usually represent each residue class by the smallest nonnegative integer which belongs to that class[2] (since this is the proper remainder which results from division). {\displaystyle \mathbb {Z} _{n}} n They write new content and verify and edit content received from contributors. is not an empty set; rather, it is isomorphic to ( Z .
