Fun Fact! Roman Numerals Were Invented as a Trading System
The method of record-keeping was widely employed across the Roman Empire for everyday tasks, allowing Romans to quickly price different commodities and services. Roman numerals were continuously employed throughout Europe after the collapse of the Roman Empire. This, however, came to an end around the 1600s. The letters I, V, X, L, C, D, and M are used to represent Roman numerals.
Fun Fact! There is just one number that is spelled with the same number of letters as the number itself.
