Se cree que los números romanos provienen de señales con las manos y marcas de conteo. El trazo I representa un dedo, la V representa el hueco entre el pulgar y los dedos para el cinco, y la X representa las manos cruzadas para el diez. Las letras L, C, D y M provienen de modificaciones de letras griegas como chi, theta y phi para representar 50, 100, 500 y 1.000. Con el tiempo, estas marcas se transformaron en las letras latinas que se reconocen hoy. No existe el 0 en el alfabeto romano, ya que el concepto del número 0 no se desarrolló plenamente hasta que la India lo inventó alrededor del 600 d.C. / 10600 HE.
