Chuvash numerals is an ancient numeral system the Chuvash people used. (Modern Chuvash use Hindu-Arabic numerals.)
Those numerals originate from finger numeration. They look like Roman numerals, but larger numerals stay at the right side. It was possible to carve those numerals on wood. In some cases numerals were preserved until the beginning of 20th century.
