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. 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 MCMLXXXII to represent 1982. Here, M is 1000, CM is 900, LXXX is 80, and II is 2. 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. III → 3.
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 8 is written as VIII, not IIIIIIII.
Let’s now learn how to write 1982 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 1982 in Roman numerals using the expansion method. To write 1982 in Roman numerals, follow the steps:
Step 1: Break the number based on the place value: thousands, hundreds, tens, and ones. For 1982, we write it as 1000 + 900 + 80 + 2
Step 2: Converting the number into Roman numerals
Step 3: Combine the Roman numerals together. Therefore, 1982 in Roman numerals is M (1000) + CM (900) + LXXX (80) + II (2) = MCMLXXXII
When writing a large number into Roman numerals, we group the number. To write 1982 in Roman numerals, we group 1982 as 1000 + 900 + 80 + 2
So, 1982 is written as MCMLXXXII in Roman numerals.
Calculate the sum of MCM and LXXXII.
A library has a collection of MM books, and it plans to distribute LXXXII books each year. How many years will it take to distribute all the books?
Find the product of XXII and XC.
What is the difference between MCMXC and VIII?
Write the Roman Numeral for 982 + M using the expansion method.
