218 in Roman Numerals

The royal titles, such as Henry I, Henry II, and so on, use Roman numerals. Have you noticed the names and wondered what these symbols (I and II) represented? Those are the Roman numerals. In earlier times, people used fingers, sticks, bones, etc., to count. As life became more 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 CCXVIII to represent 218, where CC is 200, X is 10, and VIII is 8. 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, XVIII → X + V + I + I + I → 10 + 5 + 1 + 1 + 1 = 18

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 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 8 is written as VIII, not IIIIIIII.

Let’s now learn how to write 218 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 218 in Roman numerals using the expansion method.

To write 218 in Roman numerals, follow the steps:

Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc.

For 218, we write it as 200 + 10 + 8.

Step 2: Converting the number into Roman numerals

 200 in Roman numerals — CC

 10 in Roman numerals — X

 8 in Roman numerals — VIII

Step 3: Combining the Roman numerals together.

Therefore, 218 in Roman numerals is CC (200) + X (10) + VIII (8) = CCXVIII

When writing a large number in Roman numerals, we group the numbers. 

To write 218 in Roman numerals, we group 218 as 200 + 10 + 8:

200 in Roman numerals — CC

10 in Roman numerals — X

8 in Roman numerals — VIII

So, 218 is written as CCXVIII 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 218:

CCXV = 215
CCXVI = 216
CCXVII = 217
CCXVIII = 218
CCXIX = 219
CCXX = 220

• Addition rule: The addition method is used when a large number is followed by a smaller numeral, and here the values are added. For example, CCXVIII = CC + X + VIII = 200 + 10 + 8 = 218.

• Grouping method: Here, the given numbers are grouped based on their place value, and then we convert each group into its Roman numerals. For example, 218 = 200 + 10 + 8 = CCXVIII.

• 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: This method is used when a smaller numeral precedes a larger numeral, indicating subtraction. For example, IX = 10  1 = 9.

• Place value: The numerical value that a digit has by virtue of its position in a number. For example, in 218, the place value of 2 is 200.
