The notation for 1000 was a circled or boxed X: Ⓧ, ⊗, ⊕, and by Augustinian times was partially identified with the Greek letter Φ phi. Over time, the symbol changed to Ψ and ↀ. The latter symbol further evolved into ∞, then ⋈, and eventually changed to M under the influence of the Latin word mille "thousand". [48] Della Mirandola, Pico (1486). Conclusiones sive Theses DCCCC[ Conclusions, or 900 Theses] (in Latin).
It was a common alternative to the apostrophic ↀ during the Imperial era around the Roman world (M for '1000' was not in use until the Medieval period). [50] [51] It continued in use in the Middle Ages, though it became known more commonly as titulus, [52] and it appears in modern editions of classical and medieval Latin texts.

Individual strings of stringed instruments, such as the violin, are often denoted by Roman numerals, with higher numbers denoting lower strings.
A superscript "o" (sometimes written directly above the symbol) was sometimes used as an ordinal indicator. [64] Number According to Paul Kayser, the basic numerical symbols were I, X, 𐌟 and Φ (or ⊕) and the intermediate ones were derived by taking half of those (half an X is V, half a 𐌟 is ↆ and half a Φ/⊕ is D). Then 𐌟 and ↆ developed as mentioned above. [59] Entrance to section LII (52) of the Colosseum, with numerals still visible Classical Roman numerals

A medieval accounting text from 1301 renders numbers like 13,573 as " XIII. M. V. C. III. XX. XIII", that is, "13×1000 + 5×100 + 3×20 + 13". [39] Number and place value skills are applied in many other areas of the mathematics curriculum. Knowledge of four-digit numbers and decimal numbers links to work in addition and subtraction.
Seventeen years later, in 1968, the Motion Picture Association of America (MPAA) introduced a similar label. The MPAA used X for films containing extreme violence, sexual content, and graphic language. Because the X rating was not trademarked, anyone could sell their movie as “X-rated.” a b c d Perry, David J. "Proposal to Add Additional Ancient Roman Characters to UCS" (PDF).

In some French texts from the 15th century and later, one finds constructions like IIII XXXIX for 99, reflecting the French reading of that number as quatre-vingt-dix-neuf (four-score and nineteen). [37] Similarly, in some English documents one finds, for example, 77 written as " iii xxxvii" (which could be read "three-score and seventeen"). [38]

The year of construction of the Cambridge Public Library, (USA) 1888, displayed in "standard" Roman numerals on its facade. In pharmacy, Roman numerals were used with the now largely obsolete apothecaries' system of measurement: including SS to denote "one half" and N to denote "zero". [44] [70] Letters I, X, and C can be repeated a maximum of three times but not four or more. For example: XX = 20 because X = 10, so 10 + 10 = 20 = XX
