Zero was not treated as a number at that time, but as a "vacant position". [39] Qín Jiǔsháo's 1247 Mathematical Treatise in Nine Sections is the oldest surviving Chinese mathematical text using a round symbol ‘〇’ for zero. [40] The origin of this symbol is unknown; it may have been produced by modifying a square symbol. [41]
The most commonly believed hypothesis is that it is derived from English speakers mis-hearing the French l'œuf ("the egg"), which was the name for a score of zero used in French because the symbol for a zero used on the scoreboard was an elliptical zero symbol, which visually resembled an egg. [34] [35]
An alternative, the slashed zero (looking similar to the letter O except for the slash), was primarily used in hand-written coding sheets before transcription to punched cards or tape, and is also used in old-style ASCII graphic sets descended from the default typewheel on the Teletype Model 33 ASR.
Later, they wrote numbers in almost exactly the same way as in modern times. Instead of using unique symbols for each power of ten, they wrote only the coefficients of each power of ten, with each digit separated by only a space. By the time of Alexander the Great, they had created a symbol that represented zero and was a placeholder.
Other texts show that numbers from 1 to 9 were occasionally supplemented by a placeholder known as sipos, represented as a circle or wheel, reminiscent of the eventual symbol for zero. The Arabic term for zero is ṣifr (صفر), transliterated into Latin as cifra, which became the English word cipher.
Later sources introduced conventions for the expression of zero and negative numbers. The use of a round symbol 〇 for zero is first attested in the Mathematical Treatise in Nine Sections of 1247 AD. [7] The origin of this symbol is unknown; it may have been produced by modifying a square symbol. [8]
The English language was a fusional language, this means the language makes use of inflectional changes to convey grammatical meanings. Although the inflectional complexity of English has been largely reduced in the course of development, the inflectional endings can be seen in earlier forms of English, such as the Early Modern English (abbreviated as EModE).
The Babylonians had a place-value system based essentially on the numerals for 1 and 10, using base sixty, so that the symbol for sixty was the same as the symbol for one—its value being determined from context. [11] A much later advance was the development of the idea that 0 can be considered as a number, with its own numeral.
