Roman numerals are a way of expressing numbers using symbols such as I, V, X, L, C, D, and M. Roman numerals are used in royal titles, book names, sequences, and more. Here we will be discussing Roman numerals, their rules, and examples.
Royal titles such as Henry I, Henry II, and so forth use Roman numerals. Have you noticed these symbols and wondered what they represent? Those are Roman numerals. In the past, people used fingers, sticks, and bones to count.
As life became more complex, a standard form was needed for counting. Ancient Romans used the Roman numeral system for this purpose. The symbols I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are used to count.
In Roman numerals, we use CCCLXXIV to represent 374, where CCC is 300, LXX is 70, and IV is 4. 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, LXX → L + X + X → 50 + 10 + 10 = 70.
To write a large number, certain Roman numerals can be repeated up to three times. III → 3.
If a small number precedes a large number in Roman numerals, we subtract the smaller number from the larger one. For example, IV → V - I → 5 - 1 = 4.
Symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For instance, instead of writing LLL for 150, we use CL and for 8, we write VIII instead of IIIIIIII.
Let’s now learn how to write 374 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 374 in Roman numerals using the expansion method.
To write 374 in Roman numerals, follow these steps:
Step 1: Break the number based on place value, such as ones, tens, hundreds, etc.
For 374, we write it as 300 + 70 + 4.
Step 2: Convert each number into Roman numerals:
- 300 in Roman Numerals — CCC
- 70 in Roman Numerals — LXX
- 4 in Roman Numerals — IV
Step 3: Combine the Roman numerals together:
Therefore, 374 in Roman numerals is CCC (300) + LXX (70) + IV (4) = CCCLXXIV.
When writing a large number in Roman numerals, we group the number.
To write 374 in Roman numerals, we group 374 as 300 + 70 + 4:
- 300 in Roman Numerals — CCC
- 70 in Roman Numerals — LXX
- 4 in Roman Numerals — IV
Therefore, 374 is written as CCCLXXIV in Roman numerals.
