![]() ![]() This practice continued in Asia Minor well into the Roman period. (It was not always the case that the numbers ran from highest to lowest: a 4th-century BC inscription at Athens placed the units to the left of the tens. This alphabetic system operates on the additive principle in which the numeric values of the letters are added together to obtain the total. (That this was not the traditional location of sampi in the Ionic alphabetical order has led classicists to conclude that sampi had fallen into disuse as a letter by the time the system was created. Each multiple of one hundred from 100 to 900 was then assigned its own separate letter as well, from rho to sampi. Instead of reusing these numbers to form multiples of the higher powers of ten, however, each multiple of ten from 10 to 90 was assigned its own separate letter from the next nine letters of the Ionic alphabet from iota to koppa. The units from 1 to 9 are assigned to the first nine letters of the old Ionic alphabet from alpha to theta. Greek numerals are decimal, based on powers of 10. It features each of the special numeral symbols sampi (ϡ), koppa (ϟ), and stigma (ϛ) in their minuscule forms. The first line contains the number " ͵θϡϟϛ δʹ ϛʹ", i.e. 1100 Byzantine manuscript of Hero of Alexandria's Metrika. (In general, Athenians resisted using the new numerals for the longest of any Greek state, but had fully adopted them by c. The exact dating, particularly for sampi, is problematic since its uncommon value means the first attested representative near Miletus does not appear until the 2nd century BCE, and its use is unattested in Athens until the 2nd century CE. The position of those characters within the numbering system imply that the first two were still in use (or at least remembered as letters) while the third was not. The present system uses the 24 letters adopted under Eucleides, as well as three Phoenician and Ionic ones that had not been dropped from the Athenian alphabet (although kept for numbers): digamma, koppa, and sampi. More thorough modern archaeology has caused the date to be pushed back at least to the 5th century BCE, a little before Athens abandoned its pre-Eucleidean alphabet in favour of Miletus's in 402 BCE, and it may predate that by a century or two. 19th century classicists placed its development in the 3rd century BCE, the occasion of its first widespread use. The present system probably developed around Miletus in Ionia. The same system was used outside of Attica, but the symbols varied with the local alphabets, for example, 1,000 was in Boeotia. One-half was represented by □ (left half of a full circle) and one-quarter by the right side of the circle. The numbers 50, 500, 5,000, and 50,000 were represented by the letter with minuscule powers of ten written in the top right corner:, ,, and. They were acrophonic, derived (after the initial one) from the first letters of the names of the numbers represented. Īttic numerals comprised another system that came into use perhaps in the 7th century BCE. The Minoan and Mycenaean civilizations' Linear A and Linear B alphabets used a different system, called Aegean numerals, which included number-only symbols for powers of ten: □ = 1, □ = 10, □ = 100, □ = 1000, and □ = 10000. ![]() For ordinary cardinal numbers, however, modern Greece uses Arabic numerals. In modern Greece, they are still used for ordinal numbers and in contexts similar to those in which Roman numerals are still used in the Western world. Greek numerals, also known as Ionic, Ionian, Milesian, or Alexandrian numerals, are a system of writing numbers using the letters of the Greek alphabet.
