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.

Learn how to write the number 1400 as MCD with simple explanations and conversions. Perfect for Math lovers!

How to Write 1400 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.

&nbsp;

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 MCD to represent 1400, where M is 1000, C is 100, and D is 500.

Let&rsquo;s learn more about Roman numerals and how we write them.<img alt="1400 in roman numerals" src="https://ik.imagekit.io/brightchamps/math/numbers/1400-in-roman-numerals.png" style="height:100%; margin-bottom:10px; margin-top:10px; width:100%" />

There are certain basic rules to write a number in Roman Numerals. In this section, let&rsquo;s discuss some basic rules that need to be remembered when writing a number in Roman numerals.

&nbsp;

<h3>Rule 1: Addition Method</h3>

The addition method is used when the smaller number is placed after the larger number; then it is the addition method. For example, VI &rarr; V + I &rarr; 5 + 1 = 6

&nbsp;

<h3>Rule 2: Repetition Method</h3>

To write a large number, certain Roman Numerals can be repeated up to three times. III &rarr; 3.

&nbsp;

<h3>Rule 3: Subtraction Method</h3>

If a smaller number precedes a larger number in Roman Numerals, we subtract the smaller number from the larger number, which is the subtraction method. For example, IV &rarr; V - I &rarr; 5 - 1 = 4

&nbsp;

<h3>Rule 4: Limitation Rule</h3>

The symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we won&#39;t write LL for 100 instead we use C, and 8 is written as VIII, not IIIIIIII.

Let&rsquo;s now learn how to write 1400 in Roman Numerals. Follow these methods to write the number in Roman Numerals.

&nbsp;

<ul>
	<li>By Expansion Method</li>
	<li>By Grouping Method</li>
</ul>

In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 1400 in Roman numerals using the expansion method. To write 1400 in Roman Numerals, follow the steps,

&nbsp;

Step 1: The number is broken down based on the place value, which is ones, tens, hundreds, etc. For 1400, we write it as 1000 + 400

&nbsp;

Step 2: Converting the number into Roman Numerals

<ul>
	<li>1000 in Roman Numerals - M 
	&nbsp;</li>
	<li>400 in Roman Numerals - CD</li>
</ul>

&nbsp;

Step 3: Combine the Roman Numerals together. Therefore, 1400 in Roman Numerals is M (1000) + CD (400) = MCD

1400 in Roman Numeral by Expansion Method

When writing a large number into Roman Numerals, we group the number. To write 1400 in Roman Numerals, we group 1400 as 1000 + 400

<ul>
	<li>1000 in Roman Numerals - M 
	&nbsp;</li>
	<li>400 in Roman Numerals - CD</li>
</ul>

So, 1400 is written as MCD 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 1400.&nbsp;

Common Mistakes and How to Avoid Them in 1400 Roman Numerals

Confusing with Arabic and Roman Numerals

Confusing subtraction and addition

<ul>
	<li>Addition rule: The addition method is used when a large number is followed by a smaller numeral; here, the values are added. For example, VI = V + I = 5 + 1 = 6. 
	&nbsp;</li>
	<li>Grouping method: Here, the given numbers are grouped based on their place value and then we convert each group into its Roman numerals. For example, 1400 = 1000 + 400 = MCD. 
	&nbsp;</li>
	<li>Repetition rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated only up to three times. For example, III = 3 (I is repeated three times to represent the number 3). 
	&nbsp;</li>
	<li>Subtraction rule: In the subtraction method, a smaller numeral is placed before a larger numeral to indicate subtraction. For example, IV = V - I = 5 - 1 = 4. 
	&nbsp;</li>
	<li>Limitation rule: Roman Numerals like V, L, and D cannot be repeated, and no symbol can be repeated more than three times consecutively.</li>
