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 more. Here we will be discussing Roman Numerals, rules, and examples.
The royal titles, such as Henry I, Henry II, and so on, feature Roman Numerals. Have you noticed these names and wondered what these symbols (I and II) represented? Those are Roman Numerals. Earlier people used fingers, sticks, bones, etc., to count. When life became complex, a standard form was required for counting.
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 MCMVI to represent 1906. Here, M is 1000, CM is 900 (1000 - 100), 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
To write a large number, certain Roman Numerals can be repeated up to three times. III → 3.
If a small number precedes a large number in Roman Numerals, we subtract the smaller number from the large number. For example, CM → M - C → 1000 - 100 = 900
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 we write 8 as VIII, not IIIIIIII.
Let’s now learn how to write 1906 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 1906 in Roman numerals using the expansion method. To write 1906 in Roman Numerals, follow these steps:
Step 1: Break down the number based on the place value—ones, tens, hundreds, etc. For 1906, break it as 1000 + 900 + 6.
Step 2: Converting the number into Roman Numerals
Step 3: Combine the Roman Numerals together. Therefore, 1906 in Roman Numerals is M (1000) + CM (900) + VI (6) = MCMVI
When writing a large number into Roman Numerals, we group the number. To write 1906 in Roman Numerals, we group 1906 as 1000 + 900 + 6.
So, 1906 is written as MCMVI in Roman Numerals.
A historian finds two ancient scrolls, one marked MCMI and the other MCMX. What is the total number of years represented by these scrolls?
An archaeologist discovers a chest containing MCMVI coins divided equally among XIX compartments. How many coins are in each compartment?
Calculate the sum of MCM and VI.
What is the difference between MCMX and MCMVI?
Express the sum of 1906 and 94 in Roman numerals using the expansion method.
Addition method: Used when a large number is followed by a smaller numeral; the values are added. For example, VI = V + I = 5 + 1 = 6.
