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.
The royal titles, such as Henry I, Henry II, and so on, use Roman Numerals. Have you noticed these names and wondered what these symbols (I and II) represented? Those are the Roman Numerals. Earlier, people used to count using fingers, sticks, bones, etc. When life became 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 CCCLXI to represent 361. Here, CCC is 300, LX is 60, and I is 1. 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.
Rule 1: Addition Method
The addition method is used when the smaller number is placed after the larger number. For example, XI → X + I → 10 + 1 = 11.
Rule 2: Repetition Method
To write a large number, there are certain Roman Numerals that can be repeated up to three times. III → 3.
Rule 3: Subtraction Method
If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the large number. For example, IX → X - I → 10 - 1 = 9.
Rule 4: Limitation Rule
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 361 in Roman Numerals. Follow these methods to write the number in Roman Numerals.
- By Expansion Method
- By Grouping Method
In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 361 in Roman numerals using the expansion method.
To write 361 in Roman Numerals, follow the steps,
Step 1: The number is broken based on the place value: ones, tens, hundreds, etc.
Step 2: Converting the numbers into Roman Numerals:
- 300 in Roman Numeral — CCC
- 60 in Roman Numeral — LX
- 1 in Roman Numeral — I
Step 3: Combining these Roman Numerals together:
- Therefore, 361 in Roman Numeral is CCC (300) + LX (60) + I (1) = CCCLXI.
When writing a large number into Roman Numerals, we group the number.
To write 361 in Roman Numerals, we group 361 as 300 + 60 + 1.
- 300 in Roman Numeral — CCC
- 60 in Roman Numeral — LX
- 1 in Roman Numeral — I
So, 361 is written as CCCLXI in Roman Numerals.
