1987 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 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 MCMLXXXVII to represent 1987. Here, M is 1000, CM is 900, L is 50, XXX is 30, 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 + I + I → 5 + 1 + 1 = 7

Rule 2: Repetition Method

To write a large number, certain Roman Numerals can be repeated up to three times. XXX → 30.

Rule 3: Subtraction Method

If a small number precedes 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 LL for 100; instead, we use C.

Let’s now learn how to write 1987 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 1987 in Roman numerals using the expansion method. To write 1987 in Roman Numerals, follow these steps:

Step 1: Break the number based on the place value—ones, tens, hundreds, etc. For 1987, we write it as 1000 + 900 + 80 + 7

Step 2: Convert the number into Roman Numerals

• 1000 in Roman Numeral - M

• 900 in Roman Numeral - CM

• 80 in Roman Numeral - LXXX

• 7 in Roman Numeral - VII

Step 3: Combine the Roman Numerals together. Therefore, 1987 in Roman Numeral is M (1000) + CM (900) + LXXX (80) + VII (7) = MCMLXXXVII

When writing a large number into Roman Numerals, we group the number. To write 1987 in Roman Numeral, we group 1987 as 1000 + 900 + 80 + 7

• 1000 in Roman Numeral - M

• 900 in Roman Numeral - CM

• 80 in Roman Numeral - LXXX

• 7 in Roman Numeral - VII

So, 1987 is written as MCMLXXXVII 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 1987. 

• Addition rule: The addition method is used when a large number is followed by a smaller numeral, and 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, 1987 = 1000 + 900 + 80 + 7 = MCMLXXXVII.

• Repetition rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated only up to three times. For example, XXX = 30 (X is repeated three times to represent the number 30).

• Subtraction rule: This rule is applied when a smaller numeral precedes a larger one, indicating subtraction. For instance, IV = V - I = 5 - 1 = 4.

• Limitation rule: Certain numerals, such as V, L, and D, cannot be repeated, and symbols can't be repeated more than three times.
