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.
