984 in Roman Numerals

Professor Greenline Explaining Math Concepts

Roman numerals are the 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 984 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. to count earlier. 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 CMLXXXIV to represent 984, where CM is 900, LXXX is 80, and IV is 4.

Basic Rules for 984 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, VI → V + I → 5 + 1 = 6

 

Rule 2: Repetition Method

To write a large number, there are certain Roman Numerals that can be repeated 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, it is a subtraction method. 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 we write as VIII not IIIIIIII.

How to Write 984 in Roman Numerals

Let’s now learn how to write 984 in Roman Numerals. Follow these methods to write the number in Roman Numerals.

 

  • By Expansion Method
  • By Grouping Method
Professor Greenline from BrightChamps

984 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 984 in Roman numerals using the expansion method. To write 984 in Roman Numerals, follow the steps,

 

Step 1: The number is broken based on the place value. Place value that is ones, tens, hundreds, etc. For 984, we write it as 900 + 80 + 4

 

Step 2: Converting the number into Roman Numerals

  • 900 in Roman Numerals - CM
     
  • 80 in Roman Numerals - LXXX
     
  • 4 in Roman Numerals - IV
     

Step 3: Combining the Roman Numerals together. Therefore, 984 in Roman Numerals is CM (900) + LXXX (80) + IV (4) = CMLXXXIV

Professor Greenline from BrightChamps

984 in Roman Numerals by Grouping Method

When writing a large number into Roman Numerals, we group the number. To write 984 in Roman Numerals, we group 984 as 900 + 80 + 4

  • 900 in Roman Numerals - CM
     
  • 80 in Roman Numerals - LXXX
     
  • 4 in Roman Numerals - IV

So, 984 is written as CMLXXXIV in Roman Numerals.

984 in Roman Numerals Examples

Ray, the Character from BrightChamps Explaining Math Concepts

Problem 1

A historian finds an ancient document mentioning the year CMLXXXIV. If it refers to the number of years from the founding of a city, how many years ago was the city founded if the current year is 2023?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The city was founded 1039 years ago.

Explanation

CMLXXXIV in Roman numerals is 984. To find how many years ago the city was founded, subtract 984 from 2023. 2023 - 984 = 1039. Thus, the city was founded 1039 years ago.

Problem 2

A library received a donation of CMLXXXIV books, which were to be distributed equally among VIII branches. How many books did each branch receive?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Each branch received CXXIII books.

Explanation

To find the number of books each branch received, divide the total number of books by the number of branches. CMLXXXIV = 984

VIII = 8

984 ÷ 8 = 123

123 in Roman numerals is CXXIII. Therefore, each branch received CXXIII books.

Problem 3

A treasure map shows a distance of CMLXXXIV paces to the north and CCCXLV paces to the east. What is the total distance in paces?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The total distance is MCCCXXIX paces.

Explanation

To find the total distance, add the two distances together.

CMLXXXIV = 984

CCCXLV = 345

984 + 345 = 1329

1329 in Roman numerals is MCCCXXIX. Therefore, the total distance is MCCCXXIX paces.

Problem 4

A mathematician calculates the difference between a number written as CMLXXXIV and another written as DLXV. What is the difference in Roman numerals?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The difference is CDXIX.

Explanation

The difference of two numbers is found by subtracting the smaller from the larger.

CMLXXXIV = 984

DLXV = 565

984 - 565 = 419

419 in Roman numerals is CDXIX. Thus, the difference is CDXIX.

Problem 5

Express the sum of CCCLXXXIX and CMLXXXIV using Roman numerals.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The sum is MCCCLXXIII.

Explanation

First convert the numbers to their Arabic counterparts, then add them.

CCCLXXXIX = 389

CMLXXXIV = 984

389 + 984 = 1373

1373 in Roman numerals is MCCCLXXIII. Therefore, the sum is MCCCLXXIII.
