The numeric system represented by Roman numerals originated in ancient Rome and remained the usual way of writing numbers throughout Europe well into the late Middle Ages. Numbers in this system are represented by combinations of letters from the Latin alphabet. The numbers 1 to 10 are usually expressed in Roman numerals as follows:
I, II, III, IV, V, VI, VII, VIII, IX, X
The use of Roman numerals continued long after the decline of the Roman Empire. From the 14th century on, Roman numerals began to be replaced in most contexts by the more convenient Arabic numerals (1, 2, 3, 4, 5, 6…); however, this process was gradual, and the use of Roman numerals persists in some minor applications to this day.
To make Roman numerals, we use seven letters from the alphabet. The letters, which are always capitalized, are I, V, X, L, C, D, and M.
Where are Roman numerals used today?
We can find Roman Numbers and Roman Numerals surrounding us in everyday life. The fact is, they are not really old or outdated, we just favor the easier Arabic numerals or the decimal system (1, 2, 3, 4, 5, etc).
We still use Roman Numerals or Roman Numbers for names of monarch, as symbols in math and chemistry, in movie titles and credits, as part of papers like in thesis and book writing, in clock faces, in sundials, in buildings and monuments.
