Números Romanos

Página Inicial » Ensino Fundamental » Números Romanos

Os números romanos ou algarismo romanos são usados para representar capítulos em livros, séculos, horas de relógios, nomes de reis, assembleias e muitos outras formas.

Os números romanos foram criados na Roma Antiga e eram utilizados para representar número da Europa.

Para representar os números romanos são usadas sete letras maiúscula do alfabeto latino, como mostra a tabela a seguir:

Número RomanoNomeValor
Iunus1
Vquinque5
Xdecem10
Lquinquaginta50
Ccentum100
Dquingenti500
Mmille1000

Os demais números romanos são formados pela união dessas letras.

Regra Para Representar os Números Romanos

A partir da tabela acima podemos representar diversos números romanos, para isso devemos seguir as seguintes regras:

Utilizamos a letra I somente antes de V e X;

Exemplo:

IV = 4 e IX = 9;

Utilizamos a letra X somente antes de L e C;

Exemplo:

XL = 40 e XC = 90;

Utilizamos a letra C somente antes de D e M;

Exemplo:

CD = 400 e CM = 900

Agrupamos as letras I, X, C e M somente por, no máximo, três vezes para formar alguns números;

Exemplo:

XX = 20;

MMM = 3000;

III = 3;

CCC = 300;

Representamos números romanos maiores que 4000 com o traço acima das letras, isto significa que o número foi multiplicado por mil.

Exemplo:

Regra para Converter Números Romanos para Inteiros

Agora, caso temos um número romano e queremos convertê-lo para seu respectivo número inteiro, devemos seguir as seguintes regras:

  • Se o algarismo romano é formado por algarismo de menor valor ou igual a frente do de maior valor, devemos somar os valores:
    • Exemplo:
      • XX = 10 + 10 = 20;
      • II = 1 + 1 = 2;
      • VIII = 5 + 3 = 8;
      • CCCLVI = 300 + 50 + 6 = 356;
  • Se o algarismo romano for formado por algarismo de menor valor antes do maior valor, devemos subtraí-los:
    • Exemplo:
      • IV = 5 – 1 = 4;
      • XL = 50 – 10 = 40;
      • CD = 500 – 100 = 400;
  • Algarismos romanos formados por três letras repetidas devem ser somadas:
    • Exemplo:
      • XXX = 10 + 10 + 10 = 30;
      • CCC = 100 + 100 + 100 = 300;
      • MMM = 1000 + 1000 + 1000 = 3000;
      • III = 1 + 1 + 1 = 3;
