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. 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 CCCXLVIII to represent 348. Here, CCC is 300, XL is 40, and VIII is 8. 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, there are certain Roman Numerals that can be repeated three times. For example, CCC → 300.
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. It is a subtraction method. 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 8 is written as VIII, not IIIIIIII.
Let’s now learn how to write 348 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 348 in Roman numerals using the expansion method.
To write 348 in Roman Numerals, follow the steps:
Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc.
For 348, we write it as 300 + 40 + 8.
Step 2: Convert the numbers into Roman Numerals:
- 300 in Roman Numerals — CCC
- 40 in Roman Numerals — XL
- 8 in Roman Numerals — VIII
Step 3: Combine them together.
Therefore, 348 in Roman Numerals is CCC (300) + XL (40) + VIII (8) = CCCXLVIII.
When writing a large number into Roman Numerals, we group the number.
To write 348 in Roman Numerals, we group 348 as 300 + 40 + 8:
- 300 in Roman Numerals — CCC
- 40 in Roman Numerals — XL
- 8 in Roman Numerals — VIII
So, 348 is written as CCCXLVIII in Roman Numerals.
Calculate the sum of CLXXIV and CLXXIV.
A library received CDXL books but needs to give XCVII books to a nearby school. How many books will the library have left?
What is the Roman numeral for the product of LXXXVII and IV?
A historian is examining CCCXLVIII ancient coins. If he divides them equally among VIII historians, how many coins does each historian receive?
Translate the following sequence into Roman numerals: Start with CCCXLVIII, subtract XCIV, and then add CL.
