The arithmetic operations are complex in that so many symbols are Mathematics) uses a fractional form identical to ours but with the numerator and denominator in reversed positions. Indeed, Diophantus (who came along very late in Greek Numerous, similar, representations also have been used, with increasing sophistication with time. The numerator was written with an overbar, the denominator with the diacritical mark. More complex fractions could be written as well, with context again being important.

A diacritical mark was placed after the denominator of the (unit) fraction. Their notation, however, was ambiguous and context was crucial for the correct reading a fraction. The Greeks used fractions, as did earlier civilizations. The Sand Reckoner where he computed the number of grains of sand to Archimedes extended the system in his book The letter M was used to represent numbers from 10,000 on up.Īlternatively, depending on the history one readsĪs should be evident this system does not allow very large numbers to beĮxpressed. Were represented by placing and apostrophe ' before a unit. Where three additional characters, the (digamma), the However,Ĭalculation lends itself to a great deal of skill within almost any system, the Greek system being no exception.įirst, we note that the number symbols were the same as the letters of the Greek alphabet. This made the system somewhat cumbersome to use.

Its distinguishing feature is that it was alphabetical and required the use of more than 27 different symbols for numbers plus a couple of other symbols for meaning. Like the Attic and Egyptian systems it was also decimal. The Egyptian though it was non-positional. The (Ionian) Greek system of enumeration was a little more sophisticated than By the Alexandrian Age, the Greek Attic system of enumeration was being replaced by the Ionian or alphabetic numerals. Though there was some steamlining of its use, these symbols were used in a similar way to the Egyptian system, being that symbols were used repeatedly as needed and the system was non positional. Represents 20 multiplied by the second power of M (100,000,000).The earliest numerical notation used by the Greeks was the Attic system. With αΜ indicating that the latter is multiplied The M separating the groups by commas and using the later convention ofĪccent-like upper and lower numeral signs instead of an iota superscript. I have modernized the rendering slightly by placing the power of the myriad beside, rather than above, With an additional digit to indicate the power of the M. The digits are strung together in groups of four an M preceeds the groups after the first, School of Mathematics and Statistics, University of St. The MacTutor History of Mathematics at the This rendering is based on the system proposed Historically, there were variations on how the digits were represented,Įspecially those over 9,999. To my knowledge, this is the first script of its kind published on the internet. Many Unicode Greek fonts are still missing some orĪll of these. Note that three archaic letters, ϛ (digamma or stigma),Īre used as digits, accompanied by the numeral signs ʹ and Ten thousand, with the higher digits written above or beside it.

However, for numbers greater than 9,999, the magnitude of theĭigits becomes ambiguous so the letter M (forĪcrophonic system) was included to indicate multiplication by The pattern repeated itself for thousands, with a different diacritical mark to indicate theĬhange in magnitude. Include zero, different letters were used to represent the ones, tens, and hundreds. This script converts modern Arabic numerals to the alphabetic (also referred to as the Ionian orīriefly, this was a decimal system that used letters to represent digits as shown above. “HTML” toggles the Greek number to and from HTML.
