Os números

Os números que todos usamos (1,2,3,4,5,6, etc.) são chamados “números arábicos”, para os distinguirmos dos “números romanos” (I,II,III,IV,V,VI, etc.).
Os árabes popularizaram estes números, mas a sua origem remonta aos comerciantes fenícios que os usavam para contar e fazer a contabilidade comercial.
Mas você alguma vez pensou por que motivo “1” significa "um", “2” significa "dois“, etc.?
Os números romanos são fáceis de compreender mas… Qual é a lógica que há por detrás dos números arábicos ou fenícios?
Muito simples: Trata-se de ângulos.
É pura lógica: Se você escrever o número na sua forma primitiva, verá que:
O número 1 tem um ângulo.
O número 2 tem dois ângulos.
O número 3 tem três ângulos e assim por diante.
E o "O" não tem ângulo nenhum.

E como uma imagem vale mais que mil palavras…
