10 <h3>Rule 1: Addition Method</h3>
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, DCCCXXXI → D + C + C + C + X + X + I → 500 + 100 + 100 + 100 + 10 + 10 + 1 = 831</p>

12 <h3>Rule 2: Repetition Method</h3>
12 <h3>Rule 2: Repetition Method</h3>
13 <p>To write a large number, certain Roman Numerals can be repeated three times. For example, CCC → 300.</p>

14 <h3>Rule 3: Subtraction Method</h3>
14 <h3>Rule 3: Subtraction Method</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. For example, IX → X - I → 10 - 1 = 9</p>

16 <h3>Rule 4: Limitation Rule</h3>
16 <h3>Rule 4: Limitation Rule</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 is written as VIII, not IIIIIIII.</p>
