Roman numerals are a method of expressing numbers using symbols. The symbols I, V, X, L, C, D, and M represent different values. Roman numerals are used in various contexts like royal titles, book names, sequences, and more. Here, we will discuss Roman numerals, rules, and examples.
Royal titles, such as Henry I, Henry II, and so forth, often use Roman numerals. Have you noticed these symbols (I and II) and wondered what they represent? Those are Roman numerals. In ancient times, people used fingers, sticks, and bones for counting. As life became more complex, a standard system was needed for counting. The ancient Romans developed the Roman numeral system. The symbols I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are used in this system.
In Roman numerals, we use DCCCXXVIII to represent 828. Here, D represents 500, CCC represents 300, XX represents 20, and VIII represents 8. Let’s learn more about Roman numerals and how we write them.
There are certain basic rules to write a number in Roman numerals. In this section, let’s discuss some basic rules that need to be remembered when writing a number in Roman numerals.
The addition method is used when a smaller number is placed after a larger number, indicating addition. For example, VIII → V + III → 5 + 3 = 8.
Certain Roman numerals can be repeated up to three times to represent a number. For example, CCC → 300.
If a smaller number precedes a larger number in Roman numerals, the smaller number is subtracted from the larger number. For example, IX → X - I → 10 - 1 = 9.
Symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we use X instead of VV for 10, and VIII instead of IIIIIIII for 8.
Let’s now learn how to write 828 in Roman numerals. Follow these methods to write the number in Roman numerals:
In the expansion method, a number is broken down based on its place values. In this section, we will learn how to write 828 in Roman numerals using the expansion method.
To write 828 in Roman numerals, follow these steps:
Step 1: Break the number based on place value, such as ones, tens, hundreds, etc. For 828, we write it as 800 + 20 + 8.
Step 2: Convert each number into Roman numerals:
Step 3: Combine the Roman numerals together: Therefore, 828 in Roman Numerals is DCCC (800) + XX (20) + VIII (8) = DCCCXXVIII.
When writing a large number in Roman numerals, we group the number. To write 828 in Roman numerals, we group 828 as 800 + 20 + 8.
So, 828 is written as DCCCXXVIII in Roman numerals.
