Roman numerals are an ancient numerical system that dates back to the Roman Empire. Though the Roman civilization has long since passed, this system of numbering remains in use today in various areas such as clock faces, book chapters, movie credits, and more. Understanding Roman numerals can be both a fun intellectual exercise and a practical skill, especially when encountering them in everyday life.

In this article, we will delve into the details of two specific Roman numerals: XXV and XXVIII. Both of these numerals are not only commonly used but also great examples of how the Roman numeral system functions. By the end of this article, you’ll have a thorough understanding of how these numerals are constructed, as well as how they fit into the larger Roman numeral system.

What Are Roman Numerals?

Before jumping into the specifics of XXV and XXVIII, it is important to grasp the basics of Roman numerals. Unlike the Arabic numerals (0, 1, 2, 3, etc.) we use today, Roman numerals rely on combinations of Latin letters to signify values. The main symbols in the Roman numeral system are:

• I = 1
• V = 5
• X = 10
• L = 50
• C = 100
• D = 500
• M = 1000

These symbols are combined in specific ways to form numbers. Smaller numbers are placed before larger ones to indicate subtraction, while placing smaller numbers after larger ones indicates addition. For example, IV represents 4 (5 – 1), while VI represents 6 (5 + 1). This principle is critical for understanding how Roman numerals like XXV and XXVIII are constructed.

The Breakdown of XXV (25)

Let’s start with XXV, which is the Roman numeral for 25. By breaking it down, we can see how each part contributes to the overall value.

• X represents 10, and since there are two X’s, that gives us 10 + 10, which equals 20.
• V represents 5.

When you add them together, you get 20 (XX) + 5 (V), which equals 25. Therefore, XXV is the Roman numeral representation of 25.

Where You Might Encounter XXV

Though Roman numerals are not the primary system for modern-day math, they are still used in many cultural and practical contexts. XXV is a numeral that you may often encounter in:

• Clocks: Some clock faces use Roman numerals to mark the hours. At 1 o’clock, you’ll see I, and at 12 o’clock, you’ll see XII. If you look closely at older designs, you might find XXV in minute markings, representing 25 minutes past the hour.
• Anniversaries: Roman numerals are commonly used to indicate the number of years for major anniversaries or milestones. XXV could be used to represent the 25th anniversary of an event or company.
• Books and Movies: You may find XXV used in chapter titles or movie sequels to indicate their sequence. For instance, Chapter XXV in a book refers to the 25th chapter.

Understanding XXVIII (28)

Now let’s explore XXVIII, the Roman numeral for 28. Just like XXV, understanding XXVIII requires breaking down the individual components:

• XX equals 20 (10 + 10).
• V equals 5.
• III equals 3 (1 + 1 + 1).

When you add them together, you get 20 (XX) + 5 (V) + 3 (III), which equals 28. Thus, XXVIII is the Roman numeral for 28.

Common Uses of XXVIII

XXVIII is another numeral you might encounter in similar contexts to XXV. It can be found in:

• Historical Dates: In ancient Rome, official documents, inscriptions, and calendars often used Roman numerals for dates. While we use modern numbering systems today, Roman numerals like XXVIII may still appear in historical contexts, such as the founding date of an institution.
• Sports Events: Roman numerals are widely used to mark editions of recurring events. For example, Super Bowl XXVIII refers to the 28th Super Bowl. The Olympics and other annual sports competitions also sometimes use Roman numerals to signify their chronological order.
• Legal Documents: In some cases, legal documents or formal papers may still use Roman numerals for outlining clauses or sections. This tradition has persisted in many fields, including law, because Roman numerals are often seen as formal or prestigious. Therefore, you might come across XXVIII in a legal or academic context.

Roman Numerals in Everyday Life

Although Roman numerals like XXV and XXVIII are not part of our everyday arithmetic, they play an important role in certain areas of modern life. Here are a few key areas where you might encounter Roman numerals:

• Royal Titles and Popes: Monarchs and Popes often use Roman numerals to indicate their order in history. For instance, Pope John XXIII (23) and Queen Elizabeth II (2) are two well-known examples. If we were to have a Pope John XXVIII in the future, XXVIII would indicate that he is the 28th Pope to bear the name John.
• Film Titles and Sequels: Roman numerals are frequently used in film titles, especially for sequels. The famous Star Wars series, for example, uses Roman numerals to number its episodes, with Episode IV marking the original 1977 release. You might also find XXV or XXVIII used in the title of movie sequels to denote their place in the series.
• Monuments and Inscriptions: Many older buildings, statues, and monuments have Roman numerals engraved on them, either for dates or to mark significant events. If you visit historical sites, it is not uncommon to find XXV or XXVIII as part of an inscription commemorating a particular year or event.

The Importance of Learning Roman Numerals

Learning Roman numerals like XXV and XXVIII can enhance your understanding of history, culture, and even certain academic fields. Though they are not widely used for mathematical calculations today, they remain relevant in specialized areas. Roman numerals are also an important part of classical education, helping students develop an appreciation for the way ancient civilizations recorded information.

Additionally, knowing how to read Roman numerals can prove useful in everyday life, from deciphering the date on a building to understanding movie titles or sports event numbering. While Roman numerals may seem like a small aspect of ancient history, their legacy continues to be felt in many modern contexts.

Conclusion

Roman numerals like XXV (25) and XXVIII (28) are more than just symbols from the past; they are part of a numerical system that has endured for centuries. By understanding how these numerals are constructed and where they are used, you gain insight into a fascinating piece of cultural history. Whether you encounter Roman numerals on a clock, in a book, or in the title of a movie sequel, being able to read and interpret them adds another layer of meaning to your everyday experiences.
