Roman numerals are a way of expressing numbers using symbols. I, V, X, L, C, D, and M are the symbols we use. Roman numerals are used in royal titles, book names, sequences, and so on. Here we will be discussing Roman numerals, rules, and examples.
The royal titles, such as Henry I, Henry II, and so on. Have you noticed the names and wondered what these symbols (I and II) represented? Those are the Roman numerals. Earlier people used to count using fingers, sticks, bones, etc., to count. When life became complex, a standard form was required to count.
Ancient Romans used the Roman numeral system to count. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols we use to count. In Roman numerals, we use CDLXXXIV to represent 484, where C is 100, D is 500, L is 50, X is 10, V is 5, and I is 1.
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 the smaller number is placed after the larger number. For example, VIII → V + III → 5 + 3 = 8
To write a large number, there are certain Roman numerals that can be repeated three times. For example, XXX → 30.
If a small number is followed by a large number in Roman numerals, we subtract the smaller number from the large number. For example, IX → X - I → 10 - 1 = 9
The symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we won't write VV for 10; instead, we use X, and for 8, we write VIII, not IIIIIIII.
Let’s now learn how to write 484 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 484 in Roman numerals using the expansion method. To write 484 in Roman numerals, follow the steps:
Step 1: Break the number based on the place value. Place values are hundreds, tens, ones, etc. For 484, we write it as 400 + 80 + 4
Step 2: Converting the number into Roman numerals
Step 3: Combining the Roman numerals together. Therefore, 484 in Roman Numerals is CD (400) + LXXX (80) + IV (4) = CDLXXXIV
When writing a large number into Roman numerals, we group the numbers. To write 484 in Roman numerals, we group 484 as 400 + 80 + 4
So, 484 is written as CDLXXXIV in Roman numerals.
Students make mistakes when writing a number in Roman numerals. To master Roman numerals, we can learn a few common mistakes and ways to avoid them.
A historian finds CDXXXIV ancient coins and wants to distribute them equally among XXII museums. How many coins will each museum receive?
Each museum will receive XIX coins.
To find the number of coins each museum receives, divide the total number of coins by the number of museums.
CDXXXIV / XXII
CDXXXIV = 434
XXII = 22 434 / 22 = 19
19 in Roman numerals is XIX.
Calculate the sum of CCXLII and CCXLII in Roman numerals.
The sum of CCXLII and CCXLII is CDLXXXIV.
Sum is the result of adding two numbers.
CCXLII = 242
CCXLII = 242
242 + 242 = 484
484 in Roman numerals is CDLXXXIV.
An architect is designing a building with CDLXXXIV rooms equally spread over IV floors. How many rooms are there on each floor?
There are CXXI rooms on each floor.
To find the number of rooms per floor, divide the total number of rooms by the number of floors.
CDLXXXIV / IV
CDLXXXIV = 484
IV = 4
484 / 4 = 121 1
21 in Roman numerals is CXXI.
If a library has DLX books and removes LXVI books, how many books remain? Express your answer in Roman numerals.
There are CDLXXXIV books remaining.
Subtract the number of removed books from the total number of books.
DLX = 560
LXVI = 66
560 - 66 = 494
494 in Roman numerals is CDLXXXIV.
Express the number 484 in Roman numerals using the expansion method.
The Roman numeral for 484 using the expansion method is CDLXXXIV.
Step 1: Break down the number 484 into its place values. 484 = 400 + 80 + 4 Step 2: Convert each component into Roman numerals.
400 - CD
80 - LXXX
4 - IV Combine them: 484 = CDLXXXIV.
