924 in Roman Numerals

Have you ever seen royal titles like Henry I, Henry II, and wondered what the symbols I and II represent? These are Roman Numerals. Initially, people counted using fingers, sticks, bones, etc. As life became more complex, a standardized form was required. Ancient Romans used the Roman Numeral system for counting. The symbols used are I (1), V (5), X (10), L (50), C (100), D (500), and M (1000).

In Roman Numerals, 924 is written as CMXXIV, where CM is 900 and XXIV is 24. 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. For example, XXIV → XX + IV → 20 + 4 = 24.

Rule 2: Repetition Method

To express certain numbers, some Roman Numerals can be repeated up to three times. For example, XXX → 30.

Rule 3: Subtraction Method

If a smaller number is placed before a larger number in Roman Numerals, the smaller number is subtracted from the larger one. For example, CM → M - C → 1000 - 100 = 900.

Rule 4: Limitation Rule

Symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we don't write VV for 10; instead, we use X.

Let’s now learn how to write 924 in Roman Numerals. Follow these methods to write the number in Roman Numerals:

• By Expansion Method
• By Grouping Method

In the expansion method, the number is broken down based on place value. Here’s how to write 924 in Roman numerals using the expansion method:

Step 1: Break the number based on place value (hundreds, tens, ones). For 924, write it as 900 + 20 + 4.

Step 2: Convert each part into Roman Numerals:

• 900 in Roman Numerals - CM
   
• 20 in Roman Numerals - XX
   
• 4 in Roman Numerals - IV

Step 3: Combine them: Therefore, 924 in Roman Numerals is CM (900) + XX (20) + IV (4) = CMXXIV.

When writing large numbers in Roman Numerals, group the number for clarity. To write 924 in Roman Numerals, group 924 as 900 + 20 + 4:

• 900 in Roman Numerals - CM
   
• 20 in Roman Numerals - XX
   
• 4 in Roman Numerals - IV

Thus, 924 is written as CMXXIV in Roman Numerals.

Roman Numerals follow a pattern, making similar numbers look alike. In this section, we will explore numbers related to the Roman numeral 924: 

• Addition Rule: The addition method is used when a large number is followed by a smaller numeral, and the values are added. For example, XXIV = XX + IV = 20 + 4 = 24.

• Grouping Method: Numbers are grouped based on their place value, then converted to Roman Numerals. For example, 924 = 900 + 20 + 4 = CMXXIV.

• Repetition Rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated up to three times. For example, XXX = 30.

• Subtraction Rule: A smaller numeral placed before a larger numeral indicates subtraction. For example, CM = 1000 - 100 = 900.

• Symbols: The basic symbols in Roman Numerals are I (1), V (5), X (10), L (50), C (100), D (500), and M (1000).
