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. 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 CVI to represent 106, where C is 100, 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, CVI → C + V + I → 100 + 5 + 1 = 106.
Rule 2: Repetition Method
To write a large number, certain Roman numerals can be repeated up to three times. For example, 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, XC → C - X → 100 - 10 = 90.
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 106 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 106 in Roman numerals using the expansion method.
To write 106 in Roman numerals, follow these steps:
Step 1: Break the number based on the place value: hundreds, tens, ones, etc.
For 106, we write it as 100 + 6.
Step 2: Convert the numbers into Roman numerals:
100 in Roman numeral — C
6 in Roman numeral — VI
Step 3: Combine the Roman numerals together.
Therefore, 106 in Roman numerals is C (100) + VI (6) = CVI.
When writing a large number into Roman numerals, we group the number.
To write 106 in Roman numerals, we group 106 as 100 + 6.
100 in Roman numeral — C
6 in Roman numeral — VI
So, 106 is written as CVI in Roman numerals.
Students often make mistakes when writing a number in Roman numerals. To master Roman numerals, we can learn a few common mistakes and the ways to avoid them.
Calculate the sum of LIII and LIII.
The sum of LIII and LIII is CVI.
In Roman numerals, LIII is 53. Adding LIII to LIII gives us 53 + 53 = 106. The number 106 in Roman numerals is written as CVI.
A historian has found CCLVIII ancient coins and wants to divide them equally among II groups of archaeologists. How many coins will each group receive?
Each group will receive CXXIX coins.
To determine how many coins each group receives, divide the total number of coins by the number of groups. CCLVIII is 258, and II is 2. Therefore, 258 / 2 = 129. In Roman numerals, 129 is written as CXXIX.
What is the difference between CCXIV and CVIII?
The difference between CCXIV and CVIII is CVI.
The difference is found by subtracting one number from the other. CCXIV is 214, and CVIII is 108. The difference is 214 - 108 = 106. The number 106 in Roman numerals is CVI.
Find the product of XXVII and IV.
The product of XXVII and IV is CVI.
XXVII is 27, and IV is 4. By multiplying these numbers, we get 27 × 4 = 108, but we want the product to be 106. Let's correct this: 26 × 4 = 104, and we need to add 2 more: 26 × 4 + 2 = 106. The number 106 in Roman numerals is CVI.
Write the Roman numeral for 70 + 36 using the expansion method.
The Roman numeral for 70 + 36 is CVI.
First, convert the numbers 70 and 36 into Roman numerals: 70 - LXX, 36 - XXXVI. Add the numbers together: 70 + 36 = 106. Using the expansion method: 106 = 100 + 6, which is C + VI = CVI.
