VCCXLIII

VCCXLIII is the Roman numeral representation of the number 243. This numeral is constructed using standard Roman numeral symbols: V for 5, C for 100, and X for 10, with L representing 50. The system of Roman numerals is additive, meaning symbols are generally added together to form a number. However, it also utilizes a subtractive principle in certain cases, where a smaller numeral placed before a larger one indicates subtraction.

In the case of VCCXLIII, the breakdown is as follows: C represents 100, and repeating it twice, CC, equals 200. X before L (XL) signifies 50 minus 10, resulting in 40. Finally, III represents 3 (1 + 1 + 1). Therefore, combining these values: 200 + 40 + 3 equals 243. This specific combination adheres to the established rules of Roman numeral formation. Roman numerals were widely used in ancient Rome and continued to be employed for various purposes, including numbering in books and on clocks, for many centuries.
