MCDLIII Roman Numerals

Professor Greenline Explaining Math Concepts

To meet their daily commerce and administration needs, the ancient Romans developed Roman Numerals. It used a combination of seven symbols — I, V, X, L, C, D, and M to represent numbers. Roman numerals were used to record transactions, keep track of data, and label military units. In this topic, we are going to learn about the Roman numeral MCDLIII.

What is MCDLIII in Roman Numerals?

Ancient Romans discovered that counting fingers could get very complicated after 10. To overcome this complexity, the Roman numeric system was developed. This was widely used throughout Europe as a standard writing system until the late Middle Ages.

 

Seven symbols are used to represent numbers in the Roman numeric system — I, V, X, L, C, D, and M. The numerals are made up of different combinations of these symbols. MCDLIII in Roman numerals can be written in number form by adding and subtracting the values of each Roman numeral, i.e., MCDLIII = 1453.

 

Let us learn more about the Roman numeral MCDLIII, how it is written, the mistakes commonly made, and ways to avoid these errors.

Basic Rules for MCDLIII in Roman Numerals

When writing Roman numerals, there are a few rules that we need to follow based on the Roman numerals we are trying to write. In this section, we will learn about the rules when writing Roman numerals and how to represent them.

 

Rule 1: Addition Method:

When a larger symbol is followed by a smaller symbol, we add the numerals to each other. For example, in VIII, we have 5 + 3 = 8.

 

Rule 2: Repetition Method:

A symbol that is repeated three times in continuation increases the value of the numeral. For example, XXX = 30.

 

Rule 3: Subtraction Method:

We use the subtraction method when a smaller symbol precedes a larger symbol. For example, XL = 40 (which is 50 – 10).

 

Rule 4: Limitation Rule:

Symbols cannot be repeated more than three times, and some symbols, such as V, L, and D, cannot be repeated more than once. For example, 10 is represented as X and not VV.

How to Write MCDLIII in Roman Numerals?

Let us learn how to write MCDLIII in Roman numerals. There are two methods that we can use to write Roman numerals:

 

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

MCDLIII in Roman Numeral by Expansion Method

The breaking down of Roman numerals into parts and then converting them into numerals is what we call the expansion method. The expansion method involves breaking down Roman numerals into numerical form and adding/subtracting them to get the final number.

 

Step 1: Break the Roman numerals into parts.

Step 2: Now write each of the Roman numerals with its numerical digit in the place value.

Step 3: Add the numerals together.

 

For MCDLIII,

Step 1: First, we break the Roman numerals. MCDLIII = M + (D - C) + L + I + I + I

Step 2: Write the Roman Numerals for each part The Roman Numeral M is 1000 The Roman Numeral D is 500 The Roman Numeral C is 100 The Roman Numeral L is 50 The Roman Numeral I is 1

Step 3: Combine all the numbers M + D - C + L + I + I + I = 1000 + 500 - 100 + 50 + 1 + 1 + 1 = 1453. Therefore, the Roman Numeral MCDLIII is 1453.

MCDLIII in Roman Numeral by Grouping Method

Using subtraction and addition rules, we will apply the grouping method. This means we break the Roman numerals into smaller groups, which makes it easier to work with. This method groups the Roman numerals logically, and then we write the numbers for each group.

Step 1: Take the largest number and write the number for that Roman numeral.

Step 2: Write the Roman numeral using the subtraction and addition rules.

 

Example: Let’s take the Roman numeral MCDLIII.

Step 1: The larger Roman numerals are what we will begin with. Once split, the Roman numerals we get are M, CD, L, and III. The numeral for M is 1000 The numeral for CD is 400

Step 2: Now we need to either add or subtract the smaller number, depending on its place.

 

Here we add L (50) and III (3) to MCD and we will get MCDLIII. Therefore, the numeral of MCDLIII is 1453.

Common Mistakes and How to Avoid Them in MCDLIII Roman Numerals

Students can make mistakes when studying Roman numerals. Here are a few common mistakes students make, and ways to avoid them.

Mistake 1

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Mistakes when applying the repetition method

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

It can be quite confusing for beginners to remember that Roman numerals cannot be repeated more than three times. Another thing to keep in mind is that Roman numerals such as V, L, and D cannot be repeated.

For example, writing LL as 100 is incorrect; the correct answer is C.

MCDLIII Roman Numerals Examples

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

Problem 1

What is the sum of DCLXVI and DCCLXXXVII? Write the answer in Roman numerals.

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

The sum is MCDLIII

Explanation

Convert both Roman numerals into their decimal form:

DCLXVI = 666

DCCLXXXVII = 787

Add both numbers: 666 + 787 = 1453

Convert the number into its Roman numeral: 1453 = 1000 (M) + 400 (CD) + 50 (L) + 3 (III) = MCDLIII

Problem 2

Subtract CCCXLV from MDCCXCVIII. Write the result in Roman numerals.

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

The result is MCDLIII

Explanation

Convert Roman numerals to decimal:

MDCCXCVIII = 1798

CCCXLV = 345

Subtract the numbers: 1798 - 345 = 1453

Convert 1453 into Roman numerals: 1453 = 1000 (M) + 400 (CD) + 50 (L) + 3 (III) = MCDLIII

Problem 3

If you triple CDLXXXIV, what is the result in Roman numerals?

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

MCDLII

Explanation

Convert CDLXXXIV into its decimal form:

CDLXXXIV = 484

Triple it: 484 × 3 = 1452

Write 1452 in Roman numerals: 1452 = 1000 (M) + 400 (CD) + 50 (L) + 2 (II) = MCDLII

Problem 4

Divide MMCMVI by 2 and express the answer in Roman numerals.

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

MCDLIII

Explanation

Convert MMCMVI into decimal form:

MMCMVI = 2906

Divide by 2: 2906 / 2 = 1453

Convert 1453 into Roman numerals: 1453 = 1000 (M) + 400 (CD) + 50 (L) + 3 (III) = MCDLIII

Problem 5

Write MCDLIII in decimal form.

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

In decimal form, MCDLIII is 1453

Explanation

Break MCDLIII into components:

M = 1000

CD = 400

L = 50

III = 3

Add values: 1000 + 400 + 50 + 3 = 1453
