Roman numerals are a method of expressing numbers using symbols. The symbols used are I, V, X, L, C, D, and M. Roman Numerals are commonly seen in royal titles, book names, sequences, and more. Here, we will discuss Roman Numerals, their rules, and examples.
Royal titles such as Henry I, Henry II, and so on, use Roman Numerals. Have you noticed these symbols and wondered what they represent? Those are Roman Numerals. In ancient times, people counted using fingers, sticks, bones, etc. As life became more complex, a standard form was required for counting.
The ancient Romans developed the Roman Numeral system to count. The symbols used are I (1), V (5), X (10), L (50), C (100), D (500), and M (1000). In Roman Numerals, we use DXXIV to represent 524, where D is 500, XX is 20, and IV is 4.
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. For example, DXX → D + XX → 500 + 20 = 520
To write a large number, certain Roman Numerals can be repeated up to three times. For example, XX → 20.
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
The symbols cannot be repeated more than three times, and symbols like V, L, and D cannot be repeated. For example, we don't write DD for 1000; instead, we use M.
Let’s now learn how to write 524 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 524 in Roman numerals using the expansion method. To write 524 in Roman Numerals, follow the steps,
Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc. For 524, we write it as 500 + 20 + 4
Step 2: Convert each number into Roman Numerals
Step 3: Combine the Roman Numerals together. Therefore, 524 in Roman Numerals is D (500) + XX (20) + IV (4) = DXXIV
When writing a large number in Roman Numerals, we group the number. To write 524 in Roman Numeral, we group 524 as 500 + 20 + 4
500 in Roman Numerals - D
20 in Roman Numerals - XX
4 in Roman Numerals - IV
So, 524 is written as DXXIV in Roman Numerals.
Calculate the sum of CCXLII and CCLXXXII.
A historian has DLXXIV ancient coins and wants to distribute them equally among XXII scholars. How many coins does each scholar receive?
Find the difference between DCCLXXXVI and CCLXII.
Convert the product of XXVI and XX to Roman Numerals.
Write the Roman Numeral for 300 + 224 using the expansion method.
