Roman numerals are a way of expressing numbers using symbols. The symbols used are I, V, X, L, C, D, and M. Roman Numerals are used in royal titles, book names, sequences, and more. Here we will be discussing Roman Numerals, rules, and examples.
Royal titles, such as Henry I, Henry II, and so on, often use Roman Numerals. Have you noticed these names and wondered what the symbols (I and II) represented? Those are the Roman Numerals. In ancient times, people used fingers, sticks, bones, etc., to count. As life became more complex, a standard form was required to count. Ancient Romans developed the Roman Numeral system for this purpose. The symbols I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are used to count.
In Roman Numerals, we use CCCXXVII to represent 327, where CCC is 300, XX is 20, and VII is 7. 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.
Rule 1: Addition Method
The addition method is used when a smaller number is placed after a larger number. For example, VII → V + II → 5 + 2 = 7.
Rule 2: Repetition Method
To write larger numbers, certain Roman Numerals can be repeated up to three times. For example, CCC → 300.
Rule 3: Subtraction Method
If a small number precedes a large number in Roman Numerals, we subtract the smaller number from the larger number. For example, IV → V - I → 5 - 1 = 4.
Rule 4: Limitation Rule
Symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we don't write VV for 10; instead, we use X, and for 8, we write VIII, not IIIIIIII.
Let’s now learn how to write 327 in Roman Numerals. Follow these methods to write the number in Roman Numerals.
In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 327 in Roman numerals using the expansion method.
To write 327 in Roman Numerals, follow these steps:
Step 1: Break the number based on the place value: hundreds, tens, and ones.
For 327, we write it as 300 + 20 + 7.
Step 2: Convert the numbers into Roman Numerals:
300 in Roman Numerals — CCC
20 in Roman Numerals — XX
7 in Roman Numerals — VII
Step 3: Combine the Roman Numerals together.
Therefore, 327 in Roman Numerals is CCC (300) + XX (20) + VII (7) = CCCXXVII.
When writing a large number in Roman Numerals, we group the numbers.
To write 327 in Roman Numerals, we group 327 as 300 + 20 + 7.
300 in Roman Numerals — CCC
20 in Roman Numerals — XX
7 in Roman Numerals — VII
So, 327 is written as CCCXXVII in Roman Numerals.
A historian is cataloging ancient artifacts and finds CCCXXVII relics in one chamber and LXXXV in another. How many relics are there in total?
A puzzle contains CDX pieces and a few are lost over time. If CCCXXVII pieces are left, how many pieces were lost?
An ancient manuscript contains a sequence of symbols: CCCXXVII followed by CXV. Find the product of these two numbers.
A scholar is translating a text and encounters a section where CCCXXVII soldiers are split into VII groups. How many soldiers are there per group?
Calculate the difference between DCC and CCCXXVII.
