723 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 DCCXXIII to represent 723, where D is 500, CC is 200, XX is 20, and III is 3. 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, DCCXXIII → D + CC + XX + III → 500 + 200 + 20 + 3 = 723

Rule 2: Repetition Method

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

Rule 3: Subtraction Method

If a smaller 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 723 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 723 in Roman numerals using the expansion method.

To write 723 in Roman Numerals, follow the steps:

Step 1: The number is broken down based on the place value. Place values are ones, tens, hundreds, etc.

For 723, we write it as 500 + 200 + 20 + 3

Step 2: Converting the numbers into Roman Numerals:

500 in Roman Numeral — D
200 in Roman Numeral — CC
20 in Roman Numeral — XX
3 in Roman Numeral — III

Step 3: Combining the Roman Numerals together:

Therefore, 723 in Roman Numerals is D (500) + CC (200) + XX (20) + III (3) = DCCXXIII
 

When writing a large number into Roman Numerals, we group the number.

To write 723 in Roman Numerals, we group 723 as 500 + 200 + 20 + 3.

500 in Roman Numeral — D
200 in Roman Numeral — CC
20 in Roman Numeral — XX
3 in Roman Numeral — III

So, 723 is written as DCCXXIII 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 723:
 

• Addition Rule: The addition method is used when a large number is followed by a smaller numeral; here, the values are added. For example, DCCXXIII = D + CC + XX + III = 500 + 200 + 20 + 3 = 723.

• Grouping Method: Here, the given numbers are grouped based on their place value and then converted into their Roman numerals. For example, 723 = 500 + 200 + 20 + 3 = DCCXXIII.

• 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 Rule: The subtraction method is used when a smaller numeral precedes a larger numeral. For example, IX = X - I = 9.

• Place Value: Roman numerals are often expanded and grouped based on the place values of the numbers they represent, such as ones, tens, hundreds, etc.
