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 discuss Roman numerals, rules, and examples.
The 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 to count. Ancient Romans used the Roman numeral system to count. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols we use to count.
In Roman numerals, we use CCLXV to represent 265, where C is 100, L is 50, X is 10, and V is 5. 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, XV → X + V → 10 + 5 = 15.
To write a large number, certain Roman numerals can be repeated up to three times. III → 3.
If a smaller number is placed before a larger number in Roman numerals, we subtract the smaller number from the larger number. For example, IX → X - I → 10 - 1 = 9.
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 for 8, we write VIII, not IIIIIIII.
Let’s now learn how to write 265 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 265 in Roman numerals using the expansion method.
To write 265 in Roman numerals, follow these steps:
Step 1: Break the number based on place value: hundreds, tens, and ones.
For 265, we write it as 200 + 60 + 5.
Step 2: Convert the numbers into Roman numerals:
200 in Roman numerals — CC
60 in Roman numerals — LX
5 in Roman numerals — V
Step 3: Combine the Roman numerals together.
Therefore, 265 in Roman numerals is CC (200) + LX (60) + V (5) = CCLXV.
When writing a large number in Roman numerals, we group the number. To write 265 in Roman numerals, we group 265 as 200 + 60 + 5.
200 in Roman numerals — CC
60 in Roman numerals — LX
5 in Roman numerals — V
So, 265 is written as CCLXV in Roman numerals.
