22 in Roman Numerals
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 more. Here we will be discussing Roman numerals, rules, and examples.
What is 22 in Roman Numerals?
The royal titles, such as Henry I, Henry II, and so on, use Roman numerals. Have you noticed the names and wondered what these symbols (I and II) represented? Those are the Roman numerals. Earlier, people used fingers, sticks, bones, etc., to count. When life became complex, a standard form was required. 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 used to count.
In Roman numerals, we use XXII to represent 22, where XX is 20 and II is 2. Let’s learn more about Roman numerals and how we write them.
Basic Rules for 22 in Roman Numerals
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 a smaller number is placed after a larger number. For example, XXII → XX + II → 20 + 2 = 22
Rule 2: Repetition Method
To write a large number, certain Roman numerals can be repeated up to three times. For example, XX → 20.
Rule 3: Subtraction Method
If a small number is followed by a large number in Roman numerals, we subtract the smaller number from the larger one. 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. Also, 8 is written as VIII, not IIIIIIII.
How to Write 22 in Roman Numerals
Let’s now learn how to write 22 in Roman numerals using different methods.
22 in Roman Numerals by Expansion Method
In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 22 in Roman numerals using the expansion method.
To write 22 in Roman numerals, follow these steps:
Step 1: Break the number based on the place value. For 22, we write it as 20 + 2.
Step 2: Convert the number into Roman numerals.
20 in Roman Numerals — XX
2 in Roman Numerals — II
Step 3: Combine the Roman numerals together.
Therefore, 22 in Roman numerals is XX (20) + II (2) = XXII
22 in Roman Numerals by Grouping Method
When writing a large number into Roman numerals, we group the number. To write 22 in Roman numerals, we group 22 as 20 + 2.
20 in Roman Numerals — XX
2 in Roman Numerals — II
So, 22 is written as XXII in Roman numerals.
Numbers Related to 22 in Roman Numerals
Roman numerals follow a certain pattern making them look similar. In this section, we will learn some numbers related to the Roman numeral 22.

XXI = 21
XXII = 22
XXIII = 23
XXIV = 24
XXV = 25
XXVI = 26

Common Mistakes and How to Avoid Them in 22 Roman Numerals
Students often make mistakes when writing numbers in Roman numerals. To master Roman numerals, we can learn a few common mistakes and ways to avoid them.
Mistake 1
Errors in the repetition method
The repetition method can be confusing for beginners as it states that Roman numerals cannot be repeated more than three times. In contrast, some Roman numerals such as V, L, and D cannot be repeated.
Mistake 2
Subtracting the wrong numerals
Confusion with the subtraction method can occur when a smaller number follows a larger number. For example, incorrectly writing IL for 49 instead of XLIX.
Mistake 3
Incorrect grouping
When writing a large number in Roman numerals, we should group the numbers correctly. For example, 6 should be written as VI, not IIIIII.
Mistake 4
Confusing Arabic and Roman Numerals
Students tend to confuse Arabic and Roman numerals. To avoid such errors, students need to understand the basic concepts. Arabic numbers are the numbering system using 1, 2, 3, etc., whereas Roman numerals use symbols such as I, V, X, L, etc.
Mistake 5
Confusing subtraction and addition
Students can confuse the addition and subtraction methods. When a large number follows a small one, we use the addition method; when a smaller number follows a large one, we use the subtraction method. For example, IV = V - I = 5 - 1 = 4. XV is 15, not 5, as X (10) + V (5) = 15.
22 in Roman Numerals Examples
Problem 1
Find the sum of VIII and XIV.
The sum of VIII and XIV is XXII.
Explanation
VIII is 8 and XIV is 14. The sum of 8 and 14 is 22.
22 in Roman Numerals can be written as XXII.
Problem 2
A historian has CCCXXII coins and wants to distribute them equally among XIV collectors. Find the number of coins each collector will receive.
The number of coins each collector will receive is XXIII.
Explanation
To find the number of coins each collector gets, divide the total number of coins by the number of collectors.
CCCXXII = 322
XIV = 14
322 / 14 = 23
23 in Roman Numerals can be written as XXIII.
Problem 3
What is the difference between XLIV and XXII?
The difference between XLIV and XXII is XXII.
Explanation
The difference of two numbers is the value we get when subtracting one number from the other.
XLIV = 44
XXII = 22
44 - 22 = 22
22 in Roman Numerals can be written as XXII.
Problem 4
Calculate the product of II and XI, then express the result in Roman Numerals.
The product of II and XI is XXII.
Explanation
II is 2 and XI is 11. The product of 2 and 11 is 22.
22 in Roman Numerals can be written as XXII.
Problem 5
A puzzle contains XX pieces and you accidentally lost II pieces. How many pieces are left?
The number of pieces left is XVIII.
Explanation
To find out how many pieces are left, subtract the lost pieces from the total.
XX = 20
II = 2
20 - 2 = 18
18 in Roman Numerals can be written as XVIII.
