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.

In this context, “**XLIII**” is a Roman numeral that may seem confusing to some, just like other numbers like XLV or XLII. In this article we will explore and unravel the mystery behind which Roman numeral XLIII stands for, **analyzing its structure and meaning** within the Roman numeral system.

## 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 system**which 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 M**which represent the numbers **1, 5, 10, 50, 100, 500 and 1000**respectively.

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.

In it **decimal system**, which is the number system we commonly use today, the number 43 is represented simply as ’43’. However the roman numerals** still used in certain contexts**such as on clocks, building names, book chapters, and other places where a historical look or style is sought.

Unlike Arabic numerals, which can be **wide variety of uses**such as marking the time of the clocks, representing the time in GMT as +0 or -0, to make fractions in mathematics, numbering sheets, for the DNI, the UTC time format, among others.
