Acredita-se que os números romanos tenham origem em sinais manuais e marcas de contagem. O traço I representa um dedo, o V representa o espaço entre o polegar e os dedos para o cinco, e o X representa as mãos cruzadas para o dez. As letras L, C, D e M vêm de modificações de letras gregas como chi, theta e phi para representar 50, 100, 500 e 1.000. Com o tempo, essas marcas se transformaram nas letras latinas reconhecidas hoje. Não existe 0 no alfabeto romano, pois o conceito do número 0 só se desenvolveu plenamente depois que a Índia o inventou por volta de 600 d.C. / 10600 HE.
