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, their rules, and examples.
The royal titles, such as Henry I, Henry II, and so on, include Roman Numerals. Have you noticed the names and wondered what these symbols (I and II) represented? Those are Roman Numerals.
Ancient Romans used the Roman Numeral system to count as life became more complex, requiring a standard counting form. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols used.
In Roman Numerals, we use DCLII to represent 652, where D is 500, C is 100, L is 50, and II is 2. 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 the smaller number is placed after the larger number. For example, DCLII → D + C + L + II → 500 + 100 + 50 + 2 = 652
Certain Roman Numerals can be repeated up to three times. For example, II → 2.
If a smaller number precedes a larger number in Roman Numerals, we subtract the smaller number from the larger number. 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 example, we don't write LL for 100; instead, we use C.
Let’s now learn how to write 652 in Roman Numerals. Follow these methods to write the number in Roman Numerals.
In the expansion method, based on place value, the number is broken down. In this section, we will learn how to write 652 in Roman numerals using the expansion method. To write 652 in Roman Numerals, follow the steps,
Step 1: Break the number based on place value. Place values are ones, tens, hundreds, etc. For 652, we write it as 500 + 100 + 50 + 2.
Step 2: Convert the numbers into Roman Numerals 500 in Roman Numeral — D 100 in Roman Numeral — C 50 in Roman Numeral — L 2 in Roman Numeral — II
Step 3: Combine the Roman Numerals together. Therefore, 652 in Roman Numeral is D (500) + C (100) + L (50) + II (2) = DCLII
When writing a large number into Roman Numerals, we group the numbers. To write 652 in Roman Numerals, we group 652 as 500 + 100 + 50 + 2.
So, 652 is written as DCLII in Roman Numerals.
