3 <p>Roman numerals are a 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 989 in Roman Numerals?</h2>

5 <p>The royal titles, such as Henry I, Henry II, and so on. Have you noticed the names and wondered what these<a>symbols</a>(I and II) represented? Those are the Roman Numerals. Earlier people used to count using fingers, sticks, bones, etc. When life became complex, a<a>standard form</a>was required to count.</p>

6 <p>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 CMLXXXIX to represent 989. Here, CM is 900, LXXX is 80, and IX is 9.</p>

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

8 <h2>Basic Rules for 989 in Roman Numerals</h2>

9 <p>There are certain basic rules to write a<a>number</a>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><strong>Rule 1: Addition Method</strong></h3>

11 <p>The<a>addition</a>method is used when the smaller number is placed after the larger number, then it is the addition method. For example, VIII → V + I + I + I → 5 + 1 + 1 + 1 = 8</p>

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

13 <p>To write a large number, there are certain Roman Numerals that can be repeated three times. III → 3.</p>

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

15 <p>If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the large number, it is a<a>subtraction</a>method. For example, IX → X - I → 10 - 1 = 9</p>

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

17 <p>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 we write as VIII, not IIIIIIII.</p>
