Roman numerals are a way of expressing numbers using symbols. The symbols I, V, X, L, C, D, and M are used in this system. Roman numerals are used in royal titles, book names, sequences, and more. Here, we will be discussing Roman numerals, their rules, and examples.
The royal titles, such as Henry I, Henry II, and so on, use Roman numerals. Have you noticed the names and wondered what these symbols (I and II) represented? Those are Roman numerals. In ancient times, people used fingers, sticks, bones, etc., to count. As life became more complex, a standard form of counting was needed. Ancient Romans used the Roman numeral system to count. The symbols I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are used in this system.
To represent 368 in Roman numerals, we use CCCLXVIII. Here, CCC is 300, LX is 60, and VIII is 8. Let’s learn more about Roman numerals and how we write them.
There are certain basic rules for writing numbers in Roman numerals. Let’s discuss some of these rules:
Rule 1: Addition Method
The addition method is utilized when a smaller number is placed after a larger number. For example, VIII → V + III → 5 + 3 = 8.
Rule 2: Repetition Method
Some Roman numerals can be repeated up to three times to write larger numbers. For example, CCC → 300 (C is repeated three times).
Rule 3: Subtraction Method
If a smaller number precedes a larger number, we subtract the smaller from the larger. For example, IX → X - I → 10 - 1 = 9.
Rule 4: Limitation Rule
Some symbols cannot be repeated more than three times, and 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 368 in Roman numerals. Follow these methods:
By Expansion Method
By Grouping Method
In the expansion method, the number is broken down based on place value. Here’s how to write 368 in Roman numerals using this method:
Step 1: Break the number based on place value (hundreds, tens, and ones).
368 = 300 + 60 + 8
Step 2: Convert each part into Roman numerals.
300 in Roman numerals — CCC
60 in Roman numerals — LX
8 in Roman numerals — VIII
Step 3: Combine them together.
Therefore, 368 in Roman numerals is CCC + LX + VIII = CCCLXVIII.
When writing a large number, group the number.
368 = 300 + 60 + 8
300 in Roman numerals — CCC
60 in Roman numerals — LX
8 in Roman numerals — VIII
So, 368 is written as CCCLXVIII in Roman numerals.
