742 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 742 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 DCCXLII to represent 742, where D is 500, CC is 200, XL is 40, and II is 2.

Basic Rules for 742 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 up to three times. For example, CCC → 300.

 

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, XL → L - X → 50 - 10 = 40

 

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 DD for 1000; instead, we use M and 8 we write as VIII not IIIIIIII.

How to Write 742 in Roman Numerals

Let’s now learn how to write 742 in Roman Numerals. Follow these methods to write the number in Roman Numerals.

 

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

742 in Roman Numeral 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 742 in Roman numerals using the expansion method. To write 742 in Roman Numerals, follow the steps,

 

Step 1: Break the number based on place value: hundreds, tens, and ones. For 742, write it as 700 + 40 + 2

 

Step 2: Converting the number into Roman Numerals

  • 700 in Roman Numerals - DCC
     
  • 40 in Roman Numerals - XL
     
  • 2 in Roman Numerals - II

 

Step 3: Combine the Roman Numerals together. Therefore, 742 in Roman Numerals is DCC (700) + XL (40) + II (2) = DCCXLII

Professor Greenline from BrightChamps

742 in Roman Numeral by Grouping Method

When writing a large number in Roman Numerals, we group the number. To write 742 in Roman Numerals, we group 742 as 700 + 40 + 2.

  • 700 in Roman Numerals - DCC
     
  • 40 in Roman Numerals - XL
     
  • 2 in Roman Numerals - II

So, 742 is written as DCCXLII in Roman Numerals.

742 in Roman Numerals Examples

Ray, the Character from BrightChamps Explaining Math Concepts
Max, the Girl Character from BrightChamps

Problem 1

Multiply DCCXLII by II.

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

The product of DCCXLII and II is MCDLXXXIV.

Explanation

In Roman numerals, DCCXLII is 742 and II is 2. The product of DCCXLII and II is 742 × 2 = 1484. 1484 in Roman Numerals can be written as MCDLXXXIV.

Max from BrightChamps Praising Clear Math Explanations

Problem 2

A library has MCDLXXXIV books and wants to distribute them equally among DCCXLII readers. How many books will each reader receive?

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

Each reader will receive II books.

Explanation

To find out how many books each reader receives, divide the total number of books by the number of readers. MCDLXXXIV = 1484

DCCXLII = 742

1484 / 742 = 2.

2 in Roman numerals is II.

Problem 3

Add DCCXLII and CCCXLVIII.

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

The sum of DCCXLII and CCCXLVIII is MXC.

Explanation

Adding two numbers together gives their sum.

DCCXLII = 742

CCCXLVIII = 348

742 + 348 = 1090

1090 in Roman Numerals is MXC. The sum of DCCXLII and CCCXLVIII is MXC.

Problem 4

What is the difference between MCDLXXXIV and DCCXLII?

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

The difference between MCDLXXXIV and DCCXLII is DCCXLII.

Explanation

The difference of two numbers is the value obtained when subtracting one from the other.

MCDLXXXIV = 1484

DCCXLII = 742

1484 - 742 = 742

742 in Roman Numerals is DCCXLII.

Problem 5

Write the Roman Numeral for 742 + 258 using the expansion method.

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

The Roman numeral for 742 + 258 is M.

Explanation

Step 1: Convert the numbers 742 and 258 into Roman numerals.

742 - DCCXLII

258 - CCLVIII

Add the numbers together: 742 + 258 = 1000

Using the expansion method: 1000 = M.
