Summary[edit]
DescriptionAlgarismos Arábicos 1234.JPG |
Português: Teoricamente pode-se supor que cada algarismo continha originalmente exatamente a quantidade de ângulos cujo número se desejava representar. Assim o algarismo "1" era representado por dois traços que se uniam num vórtice superior (como um "V" invertido), o "2" como um "Z", o "3" como um sigma (Σ) invertido, o "4" quase exatamente como é hoje.
English: Speculations on hypothetical origins of Indo-Arabic numerals, NOT HISTORICALLY ACCURATE: Theoretically it can be assumed that each number originally contained accurately the amount of angles whose number if desired to represent. Thus number “1” was represented as two line joined in a superior vertex (as an “inverted V”), the “2” as a “Z”, the “3” as a sigma (Σ) inverted, the “4” almost accurately as it is today. |
