804 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 for counting. 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 DCCCIV to represent 804. Here, D is 500, CCC is 300, and IV is 4. 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, then it is the addition method. For example, VI → V + I → 5 + 1 = 6

Rule 2: Repetition Method

To write a large number, certain Roman numerals can be repeated three times. CCC → 300.

Rule 3: Subtraction Method

If a small number is followed by a large number in Roman numerals, we subtract the smaller number from the large number; it is a subtraction method. 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 won't write DDD for 1500; instead, we use MD. Similarly, 8 is written as VIII, not IIIIIIII.

Let’s now learn how to write 804 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. In this section, we will learn how to write 804 in Roman numerals using the expansion method.

To write 804 in Roman numerals, follow these steps:

Step 1: Break down the number based on place value. Place value includes ones, tens, hundreds, etc. For 804, we write it as 800 + 4

Step 2: Converting the number into Roman numerals

• 800 in Roman numerals - DCCC
• 4 in Roman numerals - IV

Step 3: Combine the Roman numerals together. Therefore, 804 in Roman numerals is DCCC (800) + IV (4) = DCCCIV

When writing a large number as a Roman numeral, we group the number. To write 804 in Roman numerals, we group 804 as 800 + 4

• 800 in Roman numerals - DCCC
   
• 4 in Roman numerals - IV

So, 804 is written as DCCCIV 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 804.

• Addition Rule: The addition method is used when a large numeral is followed by a smaller numeral, and their values are added. For example, DCCCIV = DCCC + IV = 800 + 4 = 804.

• Grouping Method: Here, the given number is grouped based on its place value, and then we convert each group into its Roman numerals. For example, 804 = 800 + 4 = DCCCIV.

• 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 method is used when a smaller numeral precedes a larger numeral, and the smaller value is subtracted. For example, IV = V - I = 5 - 1 = 4.

• Place Value: Roman numerals are written by breaking down numbers based on their place values, such as hundreds, tens, and ones, to facilitate conversion.
