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.
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 DCCCXIV to represent 814, where D is 500, CCC is 300, X is 10, and IV is 4. 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, VI → V + I → 5 + 1 = 6
If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the larger 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. Similarly, 8 is written as VIII, not IIIIIIII.
Let’s now learn how to write 814 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 814 in Roman numerals using the expansion method.
To write 814 in Roman Numerals, follow the steps:
Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc. For 814, we write it as 800 + 10 + 4
Step 2: Converting the number into Roman Numerals
Step 3: Combining the Roman Numerals together. Therefore, 814 in Roman Numerals is DCCC (800) + X (10) + IV (4) = DCCCXIV
When writing a large number into Roman Numerals, we group the number. To write 814 in Roman Numerals, we group 814 as 800 + 10 + 4
So, 814 is written as DCCCXIV 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 is cataloging ancient artifacts and finds that there are DCCCXIV coins. If each display case can hold CXXII coins, how many full display cases will there be?
There will be VI full display cases.
To find the number of full display cases, divide the total number of coins by the capacity of each display case.
DCCCXIV = 814
CXXII = 122
814 / 122 = 6 (with a remainder, but only full cases count)
6 in Roman Numerals is VI.
A library received a donation of DCCCXIV books. They want to arrange them equally on XII shelves. How many books will be on each shelf?
Each shelf will have LXVII books.
To find the number of books per shelf, divide the total number of books by the number of shelves.
DCCCXIV = 814
XII = 12
814 / 12 = 67
67 in Roman Numerals is LXVII.
Calculate the sum of DCCCXIV and CCXL.
The sum of DCCCXIV and CCXL is MLIV.
Sum is the result of adding two numbers.
DCCCXIV = 814
CCXL = 240
814 + 240 = 1054
1054 in Roman Numerals is MLIV.
The sum of DCCCXIV and CCXL is MLIV.
What is the difference between DCCCXIV and CDXLIV?
The difference between DCCCXIV and CDXLIV is CCCLXX.
The difference of two numbers is the value we get when subtracting one number from another.
DCCCXIV = 814
CDXLIV = 444
814 - 444 = 370
370 in Roman Numerals is CCCLXX.
Write the Roman Numeral for 814 + 786 using the expansion method.
The Roman Numeral for 814 + 786 is MDC.
Step 1: First convert the numbers 814 and 786 into Roman numerals. 8
14 = DCCCXIV
786 = DCCLXXXVI
Add the numbers together: 814 + 786 = 1600
Using the expansion method: 1600 = 1000 + 600 = MDC.
