989 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 CMLXXXIX to represent 989. Here, CM is 900, LXXX is 80, and IX is 9.

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, VIII → V + I + I + I → 5 + 1 + 1 + 1 = 8

Rule 2: Repetition Method

To write a large number, there are certain Roman Numerals that can be repeated 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 8 we write as VIII, not IIIIIIII.

Let’s now learn how to write 989 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 989 in Roman numerals using the expansion method. To write 989 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 989, we write it as 900 + 80 + 9

Step 2: Converting the number into Roman Numerals

• 900 in Roman Numerals - CM
   
• 80 in Roman Numerals - LXXX
   
• 9 in Roman Numerals - IX

Step 3: Combining the Roman Numerals together. Therefore, 989 in Roman Numerals is CM (900) + LXXX (80) + IX (9) = CMLXXXIX

When writing a large number into Roman Numerals, we group the number. To write 989 in Roman Numerals, we group 989 as 900 + 80 + 9

• 900 in Roman Numerals - CM
   
• 80 in Roman Numerals - LXXX
   
• 9 in Roman Numerals - IX

So, 989 is written as CMLXXXIX in Roman Numerals.

Roman Numerals follow a certain pattern making it look similar. In this section, we will learn some numbers related to the Roman numeral 989.

• Addition Method: This method is used when a large number is followed by a smaller numeral, here the values are added. For example, CMLXXXIX = CM + LXXX + IX = 900 + 80 + 9 = 989
   
• Grouping Method: Here, the given numbers are grouped based on their place value and then converted into their Roman numerals. For example, 989 = 900 + 80 + 9 = CMLXXXIX
   
• Repetition Rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated only up to three times. For example, III = 3 (I is repeated three times to represent the number 3).
   
• Subtraction Method: This method is used when a smaller numeral precedes a larger one, indicating subtraction. For example, IX = X - I = 10 - 1 = 9
   
• Limitation Rule: Roman numeral symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated.
