189 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 to count using fingers, sticks, bones, etc. As 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 CLXXXIX to represent 189. Here, C is 100, L is 50, XXX is 30, 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. For example, CLXXX → C + L + XXX → 100 + 50 + 30 = 180.

Rule 2: Repetition Method

To write a large number, there are certain Roman numerals that can be repeated three times. XXX → 30.

Rule 3: Subtraction Method

If a small number is followed by 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 LL for 100; instead, we use C.

Let’s now learn how to write 189 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 189 in Roman numerals using the expansion method.

To write 189 in Roman numerals, follow the steps:

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

For 189, we write it as 100 + 80 + 9.

Step 2: Converting the number into Roman numerals:

- 100 in Roman Numeral — C
- 80 in Roman Numeral — LXXX
- 9 in Roman Numeral — IX

Step 3: Combine the Roman numerals together.

Therefore, 189 in Roman numerals is C (100) + LXXX (80) + IX (9) = CLXXXIX.

Roman numerals follow a certain pattern making them look similar. In this section, we will learn some numbers related to the Roman numeral 189.

- CLXXXIX = 189
- CXC = 190
- CXCI = 191
- CXCII = 192
- CXCIII = 193
- CXCIV = 194
- CXCV = 195
- CXCVI = 196
- CXCVII = 197
- CXCVIII = 198

• Addition Rule: The addition method is used when a large number is followed by a smaller numeral; here the values are added. For example, CLXXXIX = C + LXXX + IX = 100 + 80 + 9 = 189.

• Grouping Method: Here, the given numbers are grouped based on their place value and then converted into Roman numerals. For example, 189 = 100 + 80 + 9 = CLXXXIX.

• 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 Method: This is used when a smaller numeral precedes a larger numeral, and the smaller value is subtracted from the larger. For example, IX = 10 - 1 = 9.

• Limitation Rule: Some symbols like V, L, and D cannot be repeated. For example, L cannot be repeated for 100; instead, we use C.
