Understanding Roman Numerals

Roman numerals are a system of numerical notations used by the Romans.

The Roman numeral XXV represents the number 25. It is composed of two Xs (each representing 10) and a V (representing 5).

Applications of Roman Numerals in Modern Times

Roman numerals are not just relics of the past; they are still widely used in modern times. Here are some common applications:

• Clock Faces: Many traditional clock faces use Roman numerals to denote the hours.
• Book Chapters: Roman numerals are often used to number the preface, introduction, and prologue chapters in books.
• Monuments and Buildings: Roman numerals are frequently used to denote the year of construction on monuments and buildings.
• Super Bowl: The Super Bowl, the annual championship game of the National Football League (NFL), is denoted using Roman numerals (e.g., Super Bowl LVI).

Converting Between Roman and Arabic Numerals

Converting between Roman and Arabic numerals can be straightforward once you understand the basic rules. Here is a simple guide:

To convert a Roman numeral to an Arabic numeral, add the values of the symbols from left to right, subtracting the value of any symbol that is smaller than the symbol that follows it. For example, to convert XXV to an Arabic numeral, you would add 10 + 10 + 5 to get 25.

💡 Note: Remember that Roman numerals are typically written from largest to smallest, with the largest value on the left. However, there are exceptions, such as IV (4) and IX (9), where a smaller numeral precedes a larger one to indicate subtraction.

To convert an Arabic numeral to a Roman numeral, break down the number into its components and match each component to the corresponding Roman numeral. For example, to convert 28 to a Roman numeral, you would break it down into 20 + 5 + 3, which corresponds to XX + V + III, or XXVIII.
