The system of Ropa-Topian numerals originates in the ancient Ropa-Topian Empire. The system has remained in use in several nations in Uhuhland until today, although it has become rare since the decimal system was introduced. Especially in Uhuh-Ropa and Uhuh-Topia, Ropa-Topian numerals are commonly used in numbered lists and the numbering of major sports events, but Roman numerals are being used for the same purpose more often.

Origin

The earliest known numeral system that was used in what later became the Ropa-Topian Empire was a balanced ternary system.
