3 <p>Roman numerals are the 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, rules, and examples.</p>

4 <h2>What is 2018 in Roman Numerals?</h2>

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

6 <p>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.</p>

7 <p>Let's learn more about Roman numerals and how we write them.</p>

8 <h2>Basic Rules for 2018 in Roman Numerals</h2>

9 <p>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.</p>

10 <h3>Rule 1: Addition Method</h3>

11 <p>The<a>addition</a>method is used when the smaller number is placed after the larger number. For example, XVIII → X + V + III → 10 + 5 + 3 = 18.</p>

12 <h3>Rule 2: Repetition Method</h3>

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

14 <h3>Rule 3: Subtraction Method</h3>

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

16 <h3>Rule 4: Limitation Rule</h3>

17 <p>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.</p>
