743 in Roman Numerals

Royal titles such as Henry I, Henry II, and so on often include Roman numerals. Have you noticed the symbols and wondered what they represent? These are Roman numerals. Early people used fingers, sticks, bones, etc., to count. As life became more complex, a standardized system was needed.

The ancient Romans developed the Roman numeral system. We use I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) to count. In Roman numerals, we use DCCXLIII to represent 743, where D is 500, CC is 200, XL is 40, 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, VI → V + I → 5 + 1 = 6

Rule 2: Repetition Method

To write larger numbers, certain Roman numerals can be repeated up to three times. For example, III → 3.

Rule 3: Subtraction Method

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

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 don't write VV for 10; instead, we use X. Similarly, 8 is written as VIII, not IIIIIIII.

Let’s learn how to write 743 in Roman numerals. Follow these methods to write the number in Roman numerals:

• By Expansion Method
• By Grouping Method

In the expansion method, a number is broken down based on place value. In this section, we will learn how to write 743 in Roman numerals using the expansion method. To write 743 in Roman numerals, follow these steps:

Step 1: Break the number based on place value: hundreds, tens, and ones. For 743, we write it as 700 + 40 + 3.

Step 2: Convert the number into Roman numerals.

• 700 in Roman numerals - DCC
   
• 40 in Roman numerals - XL
   
• 3 in Roman numerals - III

Step 3: Combine the Roman numerals together. Therefore, 743 in Roman numerals is DCC + XL + III = DCCXLIII

When writing a large number in Roman numerals, we group the numbers. To write 743 in Roman numerals, we group 743 as 700 + 40 + 3.

• 700 in Roman numerals - DCC
   
• 40 in Roman numerals - XL
   
• 3 in Roman numerals - III

So, 743 is written as DCCXLIII 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 743. 

• Addition rule: The addition method is used when a larger number is followed by a smaller numeral; here, the values are added. For example, VI = V + I = 5 + 1 = 6
   
• Grouping method: Here, numbers are grouped based on their place value and then converted into Roman numerals. For example, 743 = 700 + 40 + 3 = DCCXLIII
   
• Repetition rule: Certain symbols (I, X, C, M) in the Roman numeral system can be repeated only up to three times. For example, XXX = 30 (X is repeated three times to represent 30)
   
• Subtraction rule: If a smaller numeral precedes a larger numeral, subtract the smaller from the larger. For example, IV = V - I = 4
   
• Place value: The numerical value that a digit has by virtue of its position in a number, such as hundreds, tens, and ones in the number 743.
