797 in Roman Numerals

The royal titles, such as Henry I, Henry II, and so on, often 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. When life became complex, a standard form was required. 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 DCCXCVII to represent 797. Here, D is 500, CC is 200, XC is 90, and VII is 7. 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, VII → V + II → 5 + 2 = 7

Rule 2: Repetition Method

To write a larger number, there are certain Roman Numerals that can be repeated three times. For example, CCC → 300.

Rule 3: Subtraction Method

If a smaller number is followed by a larger number in Roman Numerals, we subtract the smaller number from the larger number. For example, XC → C - X → 100 - 10 = 90

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 VVV for 15; instead, we use XV.

Let’s now learn how to write 797 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 797 in Roman numerals using the expansion method. To write 797 in Roman Numerals, follow the steps:

Step 1: Break the number based on the place value. Place values are hundreds, tens, and ones. For 797, we write it as 700 + 90 + 7

Step 2: Convert the number into Roman Numerals

• 700 in Roman Numerals - DCC
   
• 90 in Roman Numerals - XC
   
• 7 in Roman Numerals - VII

Step 3: Combine the Roman Numerals together. Therefore, 797 in Roman Numerals is DCC (700) + XC (90) + VII (7) = DCCXCVII

When writing a large number into Roman Numerals, we group the number. To write 797 in Roman Numerals, we group 797 as 700 + 90 + 7

• 700 in Roman Numerals - DCC
   
• 90 in Roman Numerals - XC
   
• 7 in Roman Numerals - VII

So, 797 is written as DCCXCVII 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 797. 

• Addition rule: The addition method is used when a large numeral is followed by a smaller one; here, the values are added. For example, VII = V + II = 5 + 2 = 7.

• Grouping method: Here, the given numbers are grouped based on their place value and then converted into Roman numerals. For example, 797 = 700 + 90 + 7 = DCCXCVII.

• Repetition rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated only up to three times. For example, CCC = 300 (C is repeated three times to represent the number 300).

• Subtraction rule: This rule is applied when a smaller numeral precedes a larger numeral, and the smaller numeral is subtracted from the larger one.

• Roman numeral basics: Understanding the basic symbols and their values such as I (1), V (5), X (10), L (50), C (100), D (500), M (1000).
