Roman numerals are a system of expressing numbers using symbols. The symbols used are 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, 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. In ancient times, 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 for counting. The symbols are: I (1), V (5), X (10), L (50), C (100), D (500), and M (1000).
In Roman Numerals, we use CVIII to represent 108. Here, C is 100, V is 5, and III is 3. 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, CVIII → C + V + III → 100 + 5 + 3 = 108.
Rule 2: Repetition Method
To write a large number, some Roman Numerals can be repeated up to three times. For example, III → 3.
Rule 3: Subtraction Method
If a smaller number precedes a larger number in Roman Numerals, we subtract the smaller number from the larger 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 don't write VV for 10; instead, we use X. For 8, we write VIII, not IIIIIIII.
Let’s now learn how to write 108 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 108 in Roman Numerals using the expansion method.
To write 108 in Roman Numerals, follow the steps:
Step 1: Break the number based on place value: Hundreds, Tens, and Ones.
For 108, we write it as 100 + 8.
Step 2: Convert the numbers into Roman Numerals.
- 100 in Roman Numerals — C.
- 8 in Roman Numerals — VIII.
Step 3: Combine the Roman Numerals.
Therefore, 108 in Roman Numerals is C (100) + VIII (8) = CVIII.
When writing a large number into Roman Numerals, we group the number. To write 108 in Roman Numerals, we group 108 as 100 + 8.
- 100 in Roman Numerals — C.
- 8 in Roman Numerals — VIII.
So, 108 is written as CVIII in Roman Numerals.
A historian is translating an ancient text and finds references to the years CVIII and CXX. Calculate the sum of these years in Roman numerals.
A museum received a donation of CCCXVI artifacts, which they decided to distribute evenly among their XXVIII display cases. How many artifacts will each display case contain?
Find the difference between CLXV and CVIII.
A collector has a total of CCCXXVIII coins. After giving away CVIII coins, how many coins does the collector have left?
Write the Roman Numeral for 108 + 59 using the expansion method.
