Roman numerals are the 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. Have you noticed the 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 CCXCVIII to represent 298. Here, C is 100, X is 10, V is 5, 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, VIII → V + III → 5 + 3 = 8
Rule 2: Repetition Method
To write a large number, certain Roman Numerals can be repeated up to three times. For example, CCC → 300.
Rule 3: Subtraction Method
If a small number precedes a large number in Roman Numerals, we subtract the smaller number from the large number. For example, XL → L - X → 50 - 10 = 40
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 298 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 298 in Roman numerals using the expansion method.
To write 298 in Roman Numerals, follow the steps:
Step 1: Break the number based on place value. Place values are ones, tens, hundreds, etc.
For 298, we write it as 200 + 90 + 8.
Step 2: Convert the number into Roman Numerals:
- 200 in Roman Numerals — CC
- 90 in Roman Numerals — XC
- 8 in Roman Numerals — VIII
Step 3: Combine the Roman Numerals together.
Therefore, 298 in Roman Numerals is CC (200) + XC (90) + VIII (8) = CCXCVIII.
When writing a large number into Roman Numerals, we group the number.
To write 298 in Roman Numerals, we group 298 as 200 + 90 + 8:
- 200 in Roman Numerals — CC
- 90 in Roman Numerals — XC
- 8 in Roman Numerals — VIII
So, 298 is written as CCXCVIII in Roman Numerals.
