Both Greek numeral systems appear instantly.
Attic (acrophonic): Used mainly in Athens, c.500-100 BC. Symbols derived from the first letter of Greek words: Π (pente = 5), Δ (deka = 10), Η (hekaton = 100), Χ (khilioi = 1000).
Ionic (alphabetic): Replaced Attic from about 400 BC onward. Uses all 27 letters of the Greek alphabet (including 3 archaic letters) as numerals. Still used for ordinals and chapter numbers in Greek texts today.
Despite the unwieldy numeral systems, ancient Greek mathematicians produced extraordinary work in geometry, number theory and astronomy. Archimedes, Euclid and Pythagoras all used these numerals. Greek numerals influenced later Roman numerals and are still used in the Orthodox Church and formal Greek texts.
