Roman numerals are a way of expressing numbers using symbols. I, V, X, L, C, D, and M are the symbols we use. Roman Numerals are used in royal titles, book names, sequences, and so on. Here we will be discussing Roman Numerals, rules, and examples.

What is 698 in Roman Numerals?

Royal titles, such as Henry I, Henry II, and so on, often use Roman Numerals like I and II. Roman Numerals have been used since ancient times when people counted with fingers, sticks, bones, etc.

As life became more complex, a standardized form of counting was needed, leading to the adoption of the Roman Numeral system. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols used for counting. In Roman Numerals, we use DCLXCVIII to represent 698, where D is 500, C is 100, LX is 60, and VIII is 8.

Let’s learn more about Roman numerals and how we write them.

Basic Rules for 698 in Roman Numerals

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, VIII → V + III → 5 + 3 = 8

Rule 2: Repetition Method

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

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. 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 for 8, we write VIII, not IIIIIIII.

698 in Roman Numerals by Expansion Method

In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 698 in Roman numerals using the expansion method. To write 698 in Roman Numerals, follow these steps:

Step 1: Break down the number based on place value. Place values are ones, tens, hundreds, etc. For 698, we write it as 500 + 100 + 90 + 8.

Step 2: Convert the number into Roman Numerals

  • 500 in Roman Numerals - D
     
  • 100 in Roman Numerals - C
     
  • 90 in Roman Numerals - XC
     
  • 8 in Roman Numerals - VIII

Step 3: Combine the Roman Numerals together. Therefore, 698 in Roman Numerals is D (500) + C (100) + XC (90) + VIII (8) = DCLXCVIII

698 in Roman Numerals by Grouping Method

When writing a large number into Roman Numerals, we group the number. To write 698 in Roman Numerals, we group 698 as 500 + 100 + 90 + 8.

  • 500 in Roman Numerals - D
     
  • 100 in Roman Numerals - C
     
  • 90 in Roman Numerals - XC
     
  • 8 in Roman Numerals - VIII

So, 698 is written as DCLXCVIII in Roman Numerals.
