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.
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. 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 DCCLIII to represent 753, where D is 500, C is 100, L is 50, and III is 3. Let’s learn more about Roman numerals and how we write them.
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.
The addition method is used when the smaller number is placed after the larger number. For example, DCCLIII → D + C + C + L + I + I + I → 500 + 100 + 100 + 50 + 1 + 1 + 1 = 753.
To write a large number, certain Roman Numerals can be repeated up to three times. III → 3.
If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the large number. For example, IX → X - I → 10 - 1 = 9.
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.
Let’s now learn how to write 753 in Roman Numerals. Follow these methods to write the number in Roman Numerals.
In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 753 in Roman numerals using the expansion method. To write 753 in Roman Numerals, follow the steps:
Step 1: Break the number based on the place value: hundreds, tens, and ones. For 753, we write it as 700 + 50 + 3.
Step 2: Converting the number into Roman Numerals:
Step 3: Combine the Roman Numerals together. Therefore, 753 in Roman Numerals is DCC (700) + L (50) + III (3) = DCCLIII
When writing a large number into Roman Numerals, we group the number. To write 753 in Roman Numerals, we group 753 as 700 + 50 + 3.
So, 753 is written as DCCLIII in Roman Numerals.
Students make mistakes when writing a number in Roman Numerals. To master Roman Numerals, we can learn a few common mistakes and the ways to avoid them.
A historian finds a document fragment mentioning the founding of Rome in DCCLIII. If the fragment also states that the event happened 500 years ago, what year was it found?
The year the document was found is MCCLIII.
The founding of Rome is mentioned as DCCLIII, which is 753 in standard numerals. If this was 500 years ago, then the document was found in 753 + 500 = 1253. 1253 in Roman Numerals is MCCLIII.
An ancient architect plans to build a structure with DCCLIII bricks distributed equally among VII layers. How many bricks are in each layer?
Each layer contains CVII bricks.
To find the number of bricks per layer, divide the total bricks by the number of layers: DCCLIII / VII. In numbers, this is 753 / 7 = 107. 107 in Roman Numerals is CVII.
A scholar is translating a text and needs to add the dates DCCLIII and CDXLV. What is the total in Roman numerals?
The sum of DCCLIII and CDXLV is MCCXCVIII.
The sum of two numbers is the result of adding them together.
DCCLIII = 753
CDXLV = 445.
753 + 445 = 1198.
1198 in Roman Numerals is MCCXCVIII.
Calculate the difference in years between the founding of Rome (DCCLIII) and the coronation of Charlemagne (DCCXCVIII).
The difference in years is XLV.
The difference between two numbers is found by subtraction:
DCCXCVIII - DCCLIII.
798 - 753 = 45.
45 in Roman Numerals is XLV.
Write the Roman numeral for the sum of 753 and 246 using the expansion method.
The Roman numeral for 753 + 246 is CMXCIX.
Step 1: Convert the numbers 753 and 246 into Roman numerals:
753 - DCCLIII
246 - CCXLVI
Add the numbers: 753 + 246 = 999
Using the expansion method: 999 = 900 + 90 + 9 = CM + XC + IX The Roman numeral for 999 is CMXCIX.
