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, their rules, and examples.
Royal titles such as Henry I, Henry II, and so on use Roman numerals to represent order. Have you noticed the symbols and wondered what they represent? Those are Roman numerals. Earlier, people used fingers, sticks, bones, etc., to count. As life became more complex, a standard form was required for counting.
Ancient Romans used the Roman numeral system, which includes the symbols I (1), V (5), X (10), L (50), C (100), D (500), and M (1000). In Roman numerals, we use CMLXXXII to represent 982, where 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, XII → X + II → 10 + 2 = 12.
Certain Roman numerals can be repeated up to three times. For example, XXX → 30.
If a smaller number is placed before a larger number, we subtract the smaller number from the larger number. For example, IX → X - I → 10 - 1 = 9.
Symbols cannot be repeated more than three times, and symbols like V, L, and D cannot be repeated. For example, we won't write VVV for 15; instead, we use XV.
Let’s now learn how to write 982 in Roman numerals. Follow these methods to write the number in Roman numerals.
In the expansion method, based on place value, the number is broken down. In this section, we will learn how to write 982 in Roman numerals using the expansion method. To write 982 in Roman numerals, follow these steps:
Step 1: Break the number based on place value: hundreds, tens, and ones. For 982, we write it as 900 + 80 + 2.
Step 2: Convert each number into Roman numerals:
Step 3: Combine the Roman numerals together. Therefore, 982 in Roman numerals is CM (900) + LXXX (80) + II (2) = CMLXXXII.
When writing a large number in Roman numerals, we group the number. To write 982 in Roman numerals, we group 982 as 900 + 80 + 2.
So, 982 is written as CMLXXXII 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 the ways to avoid them.
A historian finds DCCLXXXII coins in a chest and another CC coins in a jar. What is the total number of coins in Roman numerals?
The total number of coins is CMLXXXII.
The total number of coins is the sum of coins in the chest and jar.
DCCLXXXII = 782
CC = 200
782 + 200 = 982
982 in Roman Numerals is CMLXXXII.
A museum displays CMX paintings in one gallery and LXXII in another. Find the total number of paintings on display.
The total number of paintings on display is CMLXXXII.
To find the total number of paintings, we add the paintings in both galleries.
CMX = 910
LXXII = 72
910 + 72 = 982
982 in Roman Numerals is CMLXXXII.
An architect designed a building with CCCLXXVIII windows on one side and DCIV on the other. How many windows does the building have in total?
The building has CMLXXXII windows in total.
To find the total number of windows, we add the windows on both sides.
CCCLXXVIII = 378
DCIV = 604
378 + 604 = 982
982 in Roman Numerals is CMLXXXII.
A mathematician calculated the sum of DCCCLXXII and CX. What is their sum in Roman numerals?
The sum of DCCCLXXII and CX is CMLXXXII.
Sum is the result of adding two numbers.
DCCCLXXII = 872
CX = 110
872 + 110 = 982
982 in Roman Numerals is CMLXXXII.
What is the difference between M and XVIII in Roman numerals?
The difference between M and XVIII is CMLXXXII.
The difference of two numbers is the value we get when subtracting one number from the other.
M = 1000
XVIII = 18
1000 - 18 = 982
982 in Roman Numerals is CMLXXXII.
