408 in Roman Numerals

The royal titles, such as Henry I, Henry II, and so on, use Roman numerals. Have you noticed these names and wondered what these symbols (I and II) represented? Those are the Roman Numerals.

In earlier times, 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. 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 CDVIII to represent 408, where CD is 400 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. In this section, let’s discuss some basic rules that need to be remembered when writing numbers in Roman numerals.

Rule 1: Addition Method

The addition method is used when a smaller number is placed after a larger number; it is the addition method. For example, VIII → V + III → 5 + 3 = 8

Rule 2: Repetition Method

To write a large number, there are certain Roman Numerals that can be repeated up to three times. III → 3.

Rule 3: Subtraction Method

If a small number precedes a larger number in Roman Numerals, we subtract the smaller number from the larger number. For example, IV → V - I → 5 - 1 = 4

Rule 4: Limitation Rule

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.

Let’s learn how to write 408 in Roman Numerals. Follow these methods to write the number in Roman Numerals.

• By Expansion Method
• By Grouping Method

In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 408 in Roman numerals using the expansion method.

To write 408 in Roman Numerals, follow these steps:

Step 1: Break the number based on the place value: ones, tens, hundreds, etc. For 408, we write it as 400 + 8.

Step 2: Convert the number into Roman Numerals.

400 in Roman Numerals - CD

8 in Roman Numerals - VIII

Step 3: Combine the Roman Numerals together. Therefore, 408 in Roman Numerals is CD (400) + VIII (8) = CDVIII

When writing a larger number as a Roman Numeral, we group the number. To write 408 in Roman Numerals, we group 408 as 400 + 8.

• 400 in Roman Numerals - CD
   
• 8 in Roman Numerals - VIII
   

So, 408 is written as CDVIII in Roman Numerals.

Roman Numerals follow a certain pattern, making them look similar. In this section, we will learn some numbers related to the Roman numeral 408.

• Addition Rule: The addition method is used when a large numeral is followed by a smaller numeral; their values are added. For example, VIII = V + III = 5 + 3 = 8.
   
• Grouping Method: Here, numbers are grouped based on their place value and then converted into Roman numerals. For example, 408 = 400 + 8 = CDVIII.
   
• Repetition Rule: Certain symbols (I, X, C, M) in the Roman numeral system can be repeated up to three times. For example, III = 3 (I is repeated three times to represent the number 3).
   
• Subtraction Rule: When a smaller numeral precedes a larger one, the smaller numeral is subtracted from the larger. For example, IX = X - I = 10 - 1 = 9.
   
• Limitation Rule: Some symbols like V, L, and D cannot be repeated. For instance, 10 is represented as X, not VV.
