518 in Roman Numerals

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, II) represented? Those are the Roman Numerals. Earlier, people used fingers, sticks, bones, and other objects to count. 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 DXVIII to represent 518, where D is 500, X is 10, V is 5, and III is 3.

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.

Rule 1: Addition Method

The addition method is used when the smaller number is placed after the larger number, then it is the addition method. For example, XVIII → X + V + III → 10 + 5 + 3 = 18.

Rule 2: Repetition Method

To write a larger number, certain Roman Numerals can be repeated up to three times. III → 3.

Rule 3: Subtraction Method

If a smaller number precedes a larger number in Roman Numerals, we subtract the smaller number from the larger number. This is the subtraction method. For example, IX → X - I → 10 - 1 = 9.

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, and 8 is written as VIII, not IIIIIIII.

Let’s now learn how to write 518 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 518 in Roman numerals using the expansion method. To write 518 in Roman Numerals, follow the steps:

Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc. For 518, we write it as 500 + 10 + 8.

Step 2: Convert the number into Roman Numerals.

• 500 in Roman Numeral - D
   
• 10 in Roman Numeral - X
   
• 8 in Roman Numeral - VIII

Step 3: Combine the Roman Numerals together. Therefore, 518 in Roman Numerals is D (500) + X (10) + VIII (8) = DXVIII.

When writing a large number in Roman Numerals, we group the number. To write 518 in Roman Numerals, we group 518 as 500 + 10 + 8.

• 500 in Roman Numeral - D
   
• 10 in Roman Numeral - X
   
• 8 in Roman Numeral - VIII

So, 518 is written as DXVIII 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 518. 

• Addition rule: The addition method is used when a large number is followed by a smaller numeral; here, the values are added. For example, DXVIII = D + X + VIII = 500 + 10 + 8 = 518.
   
• Grouping method: Here, the given numbers are grouped based on their place value, and then we convert each group into its Roman numerals. For example, 518 = 500 + 10 + 8 = DXVIII.
   
• Repetition rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated only up to three times. For example, III = 3 (I is repeated three times to represent the number 3).
   
• Subtraction rule: The subtraction method is used when a smaller numeral precedes a larger numeral, and the smaller value is subtracted from the larger one. For example, IX = 10 - 1 = 9.
   
• Limitation rule: Roman numeral symbols like V, L, and D cannot be repeated. For instance, 10 is written as X, not VV.
