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 more. Here we will be discussing Roman Numerals, rules, and examples.
Roman numerals are often seen in royal titles, such as Henry I, Henry II, and so on. Have you noticed these symbols and wondered what they represent? Those are the Roman Numerals. Initially, people counted using fingers, sticks, bones, etc.
As life became complex, a standard form was required to count. Ancient Romans developed the Roman numeral system for this purpose. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols used to count.
In Roman Numerals, we use CMXIV to represent 914. Here, CM is 900, 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 a smaller number is placed after a larger number. For example, VI → V + I → 5 + 1 = 6.
To write larger numbers, certain Roman Numerals can be repeated up to three times. III → 3.
Rule 3: Subtraction Method
If a smaller number is placed before a larger 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, and 8 is written as VIII, not IIIIIIII.
Let’s now learn how to write 914 in Roman Numerals. Follow these methods to write the number in Roman Numerals.
In the expansion method, based on place value, the number is broken down. In this section, we will learn how to write 914 in Roman numerals using the expansion method. To write 914 in Roman Numerals, follow the steps:
Step 1: Break the number based on place value. For 914, the place values are hundreds, tens, and ones. For 914, we write it as 900 + 10 + 4.
Step 2: Convert the number into Roman Numerals:
Step 3: Combine the Roman Numerals together. Therefore, 914 in Roman Numeral is CM (900) + X (10) + IV (4) = CMXIV.
When writing a large number in Roman Numerals, we group the number. To write 914 in Roman Numerals, we group 914 as 900 + 10 + 4.
So, 914 is written as CMXIV in Roman Numerals.
Students make mistakes when writing numbers in Roman Numerals. To master Roman Numerals, we can learn a few common mistakes and ways to avoid them.
A historian discovered a manuscript that mentions a battle involving CMXIV warriors. If each warrior carried III weapons, how many weapons were in total?
The total number of weapons was MMMDXLII.
To find the total number of weapons, multiply the number of warriors by the number of weapons each carried.
CMXIV = 914
III = 3
Therefore, CMXIV × III = 914 × 3 = 2742.
2742 in Roman numerals is MMMDXLII.
A library received CMXIV rare books, which were to be evenly distributed among XIII shelves. How many books were placed on each shelf?
Each shelf received LXX books.
To find the number of books per shelf, divide the total number of books by the number of shelves.
CMXIV = 914
XIII = 13
914 ÷ 13 = 70
70 in Roman numerals is LXX.
Determine the total cost of CMXIV apples if each apple costs V cents.
The total cost is MMMMDLXX cents.
Multiply the number of apples by the cost per apple to find the total cost.
CMXIV = 914
V = 5 914 × 5 = 4570
4570 in Roman numerals is MMMMDLXX.
A treasure chest contains CMXIV gold coins, while another contains DCCLXXVIII. What is the total number of gold coins?
The total number of gold coins is MDCLXXXXII.
Add the number of coins in each chest to find the total.
CMXIV = 914
DCCLXXVIII = 778
914 + 778 = 1692
1692 in Roman numerals is MDCLXXXXII.
Write the Roman Numeral for 700 + 214 using the expansion method.
The Roman numeral for 700 + 214 is CMXIV.
Step 1: Convert the numbers 700 and 214 into Roman numerals.
700 = DCC
214 = CCXIV
Add the numbers together:
700 + 214 = 914
Using the expansion method:
914 = 900 + 10 + 4 = CMXIV.
