981 in Roman Numerals

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 Roman Numerals. Earlier, people used fingers, sticks, bones, etc., to count. When life became complex, a standard form was required to count.

Ancient Romans used the Roman Numeral system for this purpose. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols used. In Roman Numerals, we use CMLXXXI to represent 981. Here, CM is 900, LXXX is 80, 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 a smaller number is placed after a larger number, then it is the addition method. For example, XI → X + I → 10 + 1 = 11

Rule 2: Repetition Method

To write a large number, certain Roman Numerals can be repeated up to three times. III → 3.

Rule 3: Subtraction Method

If a small 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 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 981 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 981 in Roman numerals using the expansion method. To write 981 in Roman Numerals, follow the steps:

Step 1: The number is broken based on the place value: ones, tens, hundreds, etc. For 981, we write it as 900 + 80 + 1

Step 2: Converting the number into Roman Numerals

• 900 in Roman Numerals - CM
   
• 80 in Roman Numerals - LXXX
   
• 1 in Roman Numerals - I

Step 3: Combining these Roman Numerals together. Therefore, 981 in Roman Numerals is CM (900) + LXXX (80) + I (1) = CMLXXXI

When writing a large number into Roman Numerals, we group the numbers. To write 981 in Roman Numerals, we group 981 as 900 + 80 + 1

• 900 in Roman Numerals - CM
   
• 80 in Roman Numerals - LXXX
   
• 1 in Roman Numerals - I

So, 981 is written as CMLXXXI 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 981. 

• Addition rule: The addition method is used when a large number is followed by a smaller numeral, where the values are added. For example, CMLXXXI = CM + LXXX + I = 900 + 80 + 1 = 981
   
• 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, 981 = 900 + 80 + 1 = CMLXXXI
   
• 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: The subtraction method is used when a smaller numeral precedes a larger numeral, indicating subtraction. For example, CM = 1000 - 100 = 900.
   
• Roman numeral symbols: The basic symbols used in Roman numerals include I, V, X, L, C, D, and M, representing values of 1, 5, 10, 50, 100, 500, and 1000, respectively.
