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. 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 CDXIV to represent 414, where C is 100, D is 500, 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.
To write a large number, there are certain Roman Numerals that can be repeated up to three times. For example, III → 3.
If a smaller number is followed by a larger number in Roman Numerals, we subtract the smaller number from the larger number, which is a subtraction method. 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 414 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 414 in Roman numerals using the expansion method.
To write 414 in Roman Numerals, follow the steps:
Step 1: Break down the number based on the place value. Place values are ones, tens, hundreds, etc. For 414, we write it as 400 + 10 + 4.
Step 2: Convert the number into Roman Numerals:
400 in Roman Numerals - CD
10 in Roman Numerals - X
4 in Roman Numerals - IV
Step 3: Combine the Roman Numerals together. Therefore, 414 in Roman Numerals is CD (400) + X (10) + IV (4) = CDXIV.
When writing a large number in Roman Numerals, we group the number. To write 414 in Roman Numerals, we group 414 as 400 + 10 + 4..
So, 414 is written as CDXIV 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 ways to avoid them.
Find the sum of CD and XIV.
The sum of CD and XIV is CDXIV.
To find the sum, we add the two numbers.
CD = 400
XIV = 14
400 + 14 = 414 414 in Roman Numerals is CDXIV.
A historian is categorizing CDXIV artifacts into XIV groups. How many artifacts will be in each group?
Each group will have XXX artifacts.
To find how many artifacts are in each group, divide the total number of artifacts by the number of groups.
CDXIV = 414
XIV = 14
414 / 14 = 29 29 in Roman Numerals is XXIX.
Calculate the product of VI and LXIX.
The product of VI and LXIX is CDXIV.
In numbers, VI is 6 and LXIX is 69. The product of VI and LXIX is 6 × 69 = 414. 414 in Roman Numerals is CDXIV.
If a library adds XXIV new books to a collection of CCCXC books, what is the total number of books?
The total number of books is CDXIV.
To find the total number of books, add the new books to the existing collection.
CCCXC = 390
XXIV = 24
390 + 24 = 414 414 in Roman Numerals is CDXIV.
What is the difference when CDXIV is subtracted from DCCCLXXXVIII?
The difference is CDLXXIV.
The difference of two numbers is the value obtained by subtracting one number from another.
DCCCLXXXVIII = 888
CDXIV = 414
888 - 414 = 474 474 in Roman Numerals is CDLXXIV.
