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.
Royal titles, such as Henry I, Henry II, and so on, use Roman Numerals. Have you noticed the names and wondered what these symbols (I and II) represented? Those are Roman Numerals.
Earlier, people used fingers, sticks, bones, etc., to count. As life became more complex, a standard form was required for counting. Ancient Romans developed the Roman Numeral system. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols used.
In Roman Numerals, we use DCXIII to represent 613, where D is 500, C is 100, X is 10, and III is 3. Let’s learn more about Roman numerals and how we write them.
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.
The addition method is used when a smaller number is placed after a larger number. For example, DCXIII → D + C + X + I + I + I → 500 + 100 + 10 + 1 + 1 + 1 = 613.
Certain Roman Numerals can be repeated up to three times for larger numbers. For example, III → 3.
If a smaller number precedes a larger number, it is subtracted. For example, IX → X - I → 10 - 1 = 9.
Symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For instance, we do not write VV for 10; instead, we use X, and 8 is written as VIII, not IIIIIIII.
Let’s now learn how to write 613 in Roman Numerals. Follow these methods to write the number in Roman Numerals.
In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 613 in Roman numerals using the expansion method. To write 613 in Roman Numerals, follow the steps:
Step 1: Break the number based on place value: hundreds, tens, and ones. For 613, we write it as 500 + 100 + 10 + 3.
Step 2: Convert each number into Roman Numerals:
500 in Roman Numeral - D
100 in Roman Numeral - C
10 in Roman Numeral - X
3 in Roman Numeral - III
Step 3: Combine the Roman Numerals together. Therefore, 613 in Roman Numeral is D (500) + C (100) + X (10) + III (3) = DCXIII.
When writing a large number into Roman Numerals, we group the number. To write 613 in Roman Numerals, we group 613 as 500 + 100 + 10 + 3.
500 in Roman Numeral - D
100 in Roman Numeral - C
10 in Roman Numeral - X
3 in Roman Numeral - III
So, 613 is written as DCXIII in Roman Numerals.
