Chinese numerals are characters for writing numbers in Chinese. Today speakers of Chinese use three numeral systems: the Indian (Arabic) system used world-wide and two indigenous systems.
The more familiar indigenous system are Chinese characters that correspond to numerals in the spoken language. These are shared with other Sinospheric languages such as Japanese, Korean and Vietnamese. Most people and institutions in China primarily use the Indian (Arabic) system for convenience, with traditional Chinese numerals used mainly in some formal or ceremonial occasions such as on printed money.
The other indigenous system is the Suzhou numerals, or huama, a positional system. It is the only surviving form of the rod numerals. They were once used by Chinese mathematicians, and later in Chinese markets, such as those in Hong Kong before the 1990s, but has been gradually supplanted by the Arabic numerals.
