In Greek numeration, digits are represented by the letters of the Greek alphabet. To convert a Greek numeral into an Arabic numeral, you should know that, apart from a few exceptions, a Greek letter takes the value of its place in the alphabet from 1 to 9 (α to θ), then from 10 to 90 (ι to ϙ), and so on. A special character, called keraia / κεραῖα ʹ, is added at the top-right of the last letter to distinguish a number from a word. A left keraia ͵ placed at the bottom-left of a letter means that this letter denotes thousands, while for the same purpose the Byzantines placed a bar above the letters.
