164 in Roman Numerals

The royal titles, such as Henry I, Henry II, and so on, use Roman numerals. Have you noticed these names and wondered what the symbols (I and II) represent?

Those are Roman numerals. In ancient times, people counted using fingers, sticks, bones, etc. As life became more complex, a standard form was needed for counting. Ancient Romans used the Roman numeral system for this purpose. The symbols I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are used for counting.

In Roman numerals, we use CLXIV to represent 164. Here, C is 100, LX is 60, and IV is 4. Let’s learn more about Roman numerals and how we write them.
 

Certain basic rules must be followed when writing a number in Roman numerals. Let's discuss some important rules to remember:

Rule 1: Addition Method

The addition method is used when a smaller numeral is placed after a larger numeral. For example, CLX → C + L + X → 100 + 50 + 10 = 160.

Rule 2: Repetition Method

Some Roman numerals can be repeated up to three times to represent numbers. III → 3.

Rule 3: Subtraction Method

If a smaller numeral precedes a larger numeral, we subtract the smaller one from the larger. For example, IV → V - I → 5 - 1 = 4.

Rule 4: Limitation Rule

Symbols cannot be repeated more than three times in succession, and certain symbols like V, L, and D cannot be repeated. For example, we don't write VV for 10; instead, we use X, and 8 is written as VIII, not IIIIIIII.

Let's now learn how to write 164 in Roman numerals. Follow these methods to write the number:

• By Expansion Method
• By Grouping Method
   

In the expansion method, a number is broken down based on its place value. Here's how to write 164 in Roman numerals using this method:

Step 1: Break down the number based on place value, such as ones, tens, and hundreds.

For 164, we write it as 100 + 60 + 4.

Step 2: Convert each part into Roman numerals:

100 in Roman numerals is C.

60 in Roman numerals is LX.

4 in Roman numerals is IV.

Step 3: Combine the Roman numerals.

Therefore, 164 in Roman numerals is C (100) + LX (60) + IV (4) = CLXIV.
 

When writing a large number in Roman numerals, we group the number. To write 164 in Roman numerals, group it as 100 + 60 + 4:

100 in Roman numerals is C.

60 in Roman numerals is LX.

4 in Roman numerals is IV.

So, 164 is written as CLXIV in Roman numerals.

Roman numerals follow a certain pattern. Here are some numbers related to 164 in Roman numerals:

• Addition rule: The addition method is used when a larger numeral is followed by a smaller numeral; the values are added. Example: CLXIV = C + LX + IV = 100 + 60 + 4 = 164.

• Grouping method: Numbers are grouped based on place value and converted into Roman numerals. Example: 164 = 100 + 60 + 4 = CLXIV.

• Repetition rule: Certain symbols (I, X, C, M) in Roman numerals can be repeated up to three times. Example: III = 3 (I is repeated three times).

• Subtraction rule: The subtraction method is used when a smaller numeral precedes a larger numeral. Example: IV = 5 - 1 = 4.

• Limitation rule: Symbols cannot be repeated more than three times consecutively, and some symbols like V, L, and D cannot be repeated.
