<p>The royal titles, such as Henry I, Henry II, and so on, use Roman numerals. Have you ever noticed these<a>symbols</a>and wondered what they represent? Those are Roman numerals. In ancient times, people used fingers, sticks, bones, etc., to count. As life became more complex, a<a>standard form</a>was required. Ancient Romans developed the Roman numeral system to count. The symbols we use include I (1), V (5), X (10), L (50), C (100), D (500), and M (1000).</p>

<h3><strong>Rule 1: Addition Method</strong></h3>
10
-
<p>The<a>addition</a>method is used when a smaller number is placed after a larger number. For example, VIII → V + III → 5 + 3 = 8.</p>
11

<h3><strong>Rule 2: Repetition Method</strong></h3>
12
-
<p>To write a large number, certain Roman numerals can be repeated up to three times. III → 3.</p>
13
-
<h3><strong>Rule 3: Subtraction Method</strong></h3>
14
-
<p>If a smaller number precedes a larger number in Roman numerals, we subtract the smaller number from the larger one. For example, IX → X - I → 10 - 1 = 9.</p>
15
-
<h3><strong>Rule 4: Limitation Rule</strong></h3>
16
