2018 in Roman Numerals

The royal titles, such as Henry VIII or Louis XIV, are often denoted in Roman numerals. These symbols represent numbers, and the Roman Numeral system was used by the ancient Romans for counting.

The symbols I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are used. In Roman Numerals, 2018 is represented as MMXVIII, where MM is 2000, 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. For example, XVIII → X + V + III → 10 + 5 + 3 = 18.

Rule 2: Repetition Method

To write larger numbers, certain Roman Numerals can be repeated up to three times. For example, III → 3.

Rule 3: Subtraction Method

If a smaller number precedes a larger number, it is subtracted. For example, IV → V - I → 5 - 1 = 4.

Rule 4: Limitation Rule

Symbols cannot be repeated more than three times, and certain symbols like V, L, and D cannot be repeated. For example, we do not write VV for 10; instead, we use X.

Let’s now learn how to write 2018 in Roman Numerals. Follow these methods to write the number in Roman Numerals.

• By Expansion Method
• By Grouping Method

In the expansion method, the number is broken down based on place value. In this section, we will learn how to write 2018 in Roman numerals using the expansion method.

To write 2018 in Roman Numerals, follow the steps:

Step 1: Break the number based on place value, i.e., thousands, hundreds, tens, and units.

For 2018, we write it as 2000 + 10 + 5 + 3.

Step 2: Convert each part into Roman Numerals.

2000 in Roman Numerals — MM

10 in Roman Numerals — X

5 in Roman Numerals — V

3 in Roman Numerals — III

Step 3: Combine the Roman Numerals together.

Therefore, 2018 in Roman Numerals is MM (2000) + X (10) + V (5) + III (3) = MMXVIII.

When writing a large number in Roman Numerals, we group the number.

To write 2018 in Roman Numerals, we group 2018 as 2000 + 10 + 5 + 3.

2000 in Roman Numerals — MM

10 in Roman Numerals — X

5 in Roman Numerals — V

3 in Roman Numerals — III

So, 2018 is written as MMXVIII 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 2018. 

• Addition Rule: The addition method is used when a large number is followed by a smaller numeral; here, the values are added. For example, XVIII = X + V + III = 10 + 5 + 3 = 18.

• Grouping Method: The given numbers are grouped based on their place value and then converted into Roman numerals. For example, 2018 = 2000 + 10 + 5 + 3 = MMXVIII.

• Repetition Rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated up to three times. For example, III = 3 (I is repeated three times).

• Subtraction Rule: The subtraction method is used when a smaller numeral precedes a larger numeral. For example, IV = 4 (5 - 1).

• Limitation Rule: Symbols like V, L, and D cannot be repeated. Instead of VV for 10, we use X.
