The notations {{rn|IV}} and {{rn|IX}} can be read as "one less than five" (4) and "one less than ten" (9), although there is a tradition favouring representation of "4" as "{{rn|IIII}}" on Roman numeral clocks. | The notations {{rn|IV}} and {{rn|IX}} can be read as "one less than five" (4) and "one less than ten" (9), although there is a tradition favouring representation of "4" as "{{rn|IIII}}" on Roman numeral clocks. | ||
Other common uses include year numbers on monuments and buildings and copyright dates on the title screens of movies and television programs. {{rn|MCM}}, signifying "a thousand, and a hundred less than another thousand", means 1900, so 1912 is written {{rn|MCMXII}}. For the years of this century, {{rn|MM}} indicates 2000.

Another system was the vinculum, in which conventional Roman numerals were multiplied by 1,000 by adding a "bar" or "overline". It was a common alternative to the apostrophic {{rn|ↀ}} during the Imperial era: both systems were in simultaneous use around the Roman world ({{rn|M}} for '1000' was not in use until the Medieval period). The use of vinculum for multiples of 1,000 can be observed, for example, on the milestones erected by Roman soldiers along the Antonine Wall in the mid-900s AUC (2nd century AD). The vinculum for marking 1,000s continued in use in the Middle Ages. | Another system was the vinculum, in which conventional Roman numerals were multiplied by 1,000 by adding a "bar" or "overline".
