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 more. Here we will be discussing Roman numerals, rules, and examples.</p>

4 <h2>What is 458 in Roman Numerals?</h2>

5 <p>In royal titles, such as Henry I, Henry II, and so on, Roman numerals are used to denote order. Have you noticed the names and wondered what these<a>symbols</a>(I and II) represented? Those are Roman numerals.</p>

6 <p>Earlier, people used fingers, sticks, bones, etc., to count. When life became more complex, a<a>standard form</a>was required for counting. Ancient Romans used the Roman numeral system for this purpose. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols we use to count.</p>

7 <p>In Roman numerals, we use CDL VIII to represent 458. C is 100, D is 500, L is 50, and VIII is 8. Let’s learn more about Roman numerals and how to write them.</p>

8 <h2>Basic Rules for 458 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 a smaller number is placed after a larger number. For example, VIII → V + III → 5 + 3 = 8</p>

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

13 <p>To write a larger number, certain Roman numerals can be repeated up to three times. III → 3.</p>

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

15 <p>If a smaller number precedes a larger number in Roman numerals, we subtract the smaller number from the larger number. For example, XL → L - X → 50 - 10 = 40</p>

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

17 <p>Symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, 20 is written as XX, not VVVV.</p>
