Church Slavonic numerals are a Cyrillic alphanumeric system used historically in Russian and other Slavic Orthodox cultures. Letters of the early Cyrillic alphabet are assigned numerical values.
Like Greek numerals, Church Slavonic uses separate letter groups for units (1–9), tens (10–90), and hundreds (100–900). A titlo mark ( ҃) is placed above one of the letters to indicate it is a number. Thousands are marked with a special symbol (҂) placed before the number. The number ends with a period.
