Roman numerals are a system of representing numbers using symbols. The symbols I, V, X, L, C, D, and M are used. Roman numerals are applied in various contexts, including royal titles, book names, sequences, and more. Here, we will explore Roman numerals, rules, and examples.
Royal titles like Henry I and Henry II use Roman numerals. Have you noticed these symbols (I and II) and wondered what they represent?
They are Roman numerals. In the past, people used fingers, sticks, and bones to count. As life became more complex, a standardized counting system was required. Ancient Romans developed the Roman numeral system. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols used for counting.
In Roman numerals, we use MCMXCVII to represent 1997. Here, M stands for 1000, CM for 900, XC for 90, and VII for 7. Let’s learn more about Roman numerals and how we write them.
There are certain basic rules for writing 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 follows a larger number. For example, VII → V + II → 5 + 2 = 7.
Certain Roman numerals can be repeated up to three times to represent larger numbers. For example, XXX → 30.
If a smaller number precedes a larger number, it is subtracted. For example, XC → C - X → 100 - 10 = 90.
Symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we write 10 as X, not VV, and 8 as VIII, not IIIIIIII.
Let’s learn how to write 1997 in Roman numerals. Follow these methods to write the number in Roman numerals:
In the expansion method, based on place value, the number is broken down. In this section, we will learn how to write 1997 in Roman numerals using the expansion method.
To write 1997 in Roman numerals, follow these steps:
Step 1: Break the number based on place value: thousands, hundreds, tens, and ones. For 1997, write it as 1000 + 900 + 90 + 7.
Step 2: Convert each number into Roman numerals:
1000 in Roman numerals — M
900 in Roman numerals — CM
90 in Roman numerals — XC
7 in Roman numerals — VII
Step 3: Combine the Roman numerals:
Therefore, 1997 in Roman numerals is M (1000) + CM (900) + XC (90) + VII (7) = MCMXCVII.
When writing a large number in Roman numerals, we group the numbers.
To write 1997 in Roman numerals, group 1997 as 1000 + 900 + 90 + 7:
1000 in Roman numerals — M
900 in Roman numerals — CM
90 in Roman numerals — XC
7 in Roman numerals — VII
So, 1997 is written as MCMXCVII in Roman numerals.
