25 in Roman Numerals

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 XXV to represent 25, where XX is 20, and V is 5. 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; then it is the addition method. For example, XXV → XX + V → 20 + 5 = 25.

Rule 2: Repetition Method

To write a large number, there are certain Roman Numerals that can be repeated up to three times. 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; it is a subtraction method. 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 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 25 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 25 in Roman numerals using the expansion method.

To write 25 in Roman Numerals, follow the steps:

Step 1: Break the number based on the place value. Place value that is ones, tens, hundreds, etc.

For 25, we write it as 20 + 5.

Step 2: Convert the numbers into Roman Numerals.

20 in Roman Numeral — XX

5 in Roman Numeral — V

Step 3: Combine the Roman Numerals together.

Therefore, 25 in Roman Numeral is XX (20) + V (5) = XXV.
 

When writing a large number into Roman Numeral, we group the number. To write 25 in Roman Numeral, we group 25 as 20 + 5.

20 in Roman Numeral — XX

5 in Roman Numeral — V

So, 25 is written as XXV 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 25.

XXIV = 24
XXV = 25
XXVI = 26
XXVII = 27
XXVIII = 28
XXIX = 29
 

• Addition rule: The addition method is used when a large number is followed by a smaller numeral; here, the values are added. For example, XXV = XX + V = 20 + 5 = 25.
   
• Grouping method: Here, the given numbers are grouped based on their place value, and then we convert each group into its Roman numerals. For example, 25 = 20 + 5 = XXV.
   
• Repetition rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated only up to three times. For example, XXX = 30 (X is repeated three times to represent the number 30).
   
• Subtraction rule: This rule is used when a smaller numeral precedes a larger numeral, indicating that the smaller numeral should be subtracted from the larger one. For example, IX = 10 - 1 = 9.
   
• Place value: Roman numerals do not have a place value system like Arabic numerals, but they do have significant digits that dictate how they are read and combined. For example, in XXV, the first X is the tens place, and V is the units place.
