CONGRUÈNCIES

Per a escomençar, parlaré dels mòduls i dels diferents usos de les cogruències. El signe de les congruències es representa per el signe igual (=) però amb tres ratlles (no disponible al teclat de l'ordinador) així que ho representaré diguent "és congruent a".

APLICACIONS DE L'ARITMÈTICA MODULAR

L'aritmètica modular, estudiada sistemàticament en primer lloc per Carl Friedrich Gauss al final del Segle XVIII, s'aplica en teoria de números, àlgebra abstracta, criptografia, i en arts visuals i musicals. Les operacions aritmètiques que hui en dia fan la majoria de les computadores són aritmètic modulars, on el mòdul és 2b (b és el nombre de bits dels valors sobre els quals operamos). Açò es veu clar en la compilació de llenguatges de programació com el C; on per exemple totes les operacions aritmètiques sobre 'int', sencers, es prenen mòdul 232 en la majoria de les computadores.
En l'art
En música, a causa de l'equivalència d'octaves i equivalència enarmònica (esto és, els passos en raons de 1/2 o 2/1 són equivalents, i Do# és el mateix que Reb), l'aritmètica modular s'usa quan considerem l'escala de dotze tons igualment temperada, especialment en el dodecafonisme.
