The system of Old Russian numerals in which every integer from 1 to 9, and also tens and hundreds, were denoted by letters of the Slavic alphabet with a sign (titlo) written above them. Integers up to 999 were compiled by placing Slavic numerals in adjacent positions. Thousands were denoted by prefixing a certain sign to the number to express the number of thousands.
Thus, the Slavic numeral system is an adaptation of e.g. the Greek system, cf. also Numbers, representations of.
