# What Roman numeral is XLIII?

The Roman numeral system, used by the ancient Roman civilization, is known for its use of letters to represent numbers. Each letter has a specific numerical value and the combination of these are added to obtain the total value.

## What number is XLIII?

is a roman numeral represents the number 43 in decimal numbering.

In the Roman numeral system, the letters of the Roman alphabet were used to represent specific numerical values. Numbers are written from left to right, and letters can be added or subtracted to get the desired numerical value. The letters ‘X’, ‘L’ and ‘I’ represent the figures of 10, 50 and 1, respectively, and based on a specific order they could determine higher or lower values.

Roman numerals developed in ancient Rome around the 7th century BC and were widely used throughout the Roman Empire. These were based on a additive numbering systemwhich means that the values ​​were added together to get larger numbers.

They used a numbering system that required the use of letters of the Roman alphabet. The letters used in Roman numerals are: I, V, X, L, C, D and Mwhich represent the numbers 1, 5, 10, 50, 100, 500 and 1000respectively.

In the Roman numeral system letters are written from left to right and, furthermore, they can be combined in various ways to represent different numbers.

• When a letter of lesser value stands in front of a letter of greater value, is subtracted the letter with the highest value with the letter of the lowest value.
• When a letter of lesser value is placed after of a letter of greater value, adds its value to the value of the highest value letter.

The ‘x‘ in XLIII represents the number 10 in Roman numerals and the ‘L‘ the number 50. When a lower value letter, such as ‘X’, is placed before a higher value letter, such as ‘L’, its value is subtracted. Therefore ‘XL‘ represents 50 – 10, which is equal to 40. The ‘III’ represents the number 1 + 1 + 1, which is equal to 3. When adding ‘XL‘ (40) with ‘II‘ (3), we obtain XLIII, which represents the number 43 in roman numerals. This applies regardless of whether they are low values ​​like XII or very high values ​​like MCDXLIV.
