1987 in Roman Numerals

Professor Greenline Explaining Math Concepts

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 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.

Basic Rules for 1987 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 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.

How to Write 1987 in Roman Numerals

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
Professor Greenline from BrightChamps

1987 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 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

Professor Greenline from BrightChamps

1987 in Roman Numerals by Grouping Method

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.
