Roman numerals are a way of expressing numbers using symbols. I, V, X, L, C, D, and M are the symbols used. Roman numerals are utilized 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 symbols and wondered what they represent? Those are Roman numerals.
In ancient times, people counted using fingers, sticks, and bones. As life became more complex, a standardized form of counting was needed, leading to the development of the Roman numeral system. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols used.
In Roman numerals, we use DCXXVI to represent 626, where D is 500, C is 100, X is 10, and VI is 6. 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, VI → V + I → 5 + 1 = 6
Certain Roman numerals can be repeated up to three times. III → 3.
If a smaller number precedes a larger number, it 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 won't write VV for 10; instead, we use X.
Let’s now learn how to write 626 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 626 in Roman numerals using the expansion method. To write 626 in Roman numerals, follow these steps:
Step 1: Break the number based on place value (ones, tens, hundreds, etc.). For 626, we write it as 600 + 20 + 6.
Step 2: Convert each number into Roman numerals.
600 in Roman numeral - DC
20 in Roman numeral - XX
6 in Roman numeral - VI
Step 3: Combine the Roman numerals. Therefore, 626 in Roman numerals is DC + XX + VI = DCXXVI
When writing a large number in Roman numerals, we group the number. To write 626 in Roman numerals, we group 626 as 600 + 20 + 6.
600 in Roman numeral - DC
20 in Roman numeral - XX
6 in Roman numeral - VI
So, 626 is written as DCXXVI in Roman numerals.
Calculate the sum of DCXXVI and LXXIV.
A historian finds DCCCXXVI ancient coins and wants to distribute them equally among XIII museums. How many coins will each museum receive?
A construction company needs to install DCLXII tiles in each of IX buildings. What is the total number of tiles required?
If you subtract CCCXVI from DCXXVI, what is the result in Roman numerals?
Write the Roman numeral for 600 + 26 using the expansion method.
