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.
Royal titles, such as Henry I, Henry II, and so on, feature Roman numerals. Have you noticed these symbols (like I and II) and wondered what they represent? Those are Roman numerals. Earlier people used fingers, sticks, bones, etc., to count. As life became more complex, a standard form was needed. 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.
In Roman numerals, we use CMLXIV to represent 964, where CM is 900, LX is 60, and IV is 4. Let’s learn more about Roman numerals and how we write them.
There are certain basic rules for writing 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, XI → X + I → 10 + 1 = 11.
To write a large number, certain Roman numerals can be repeated up to three times. For example, III → 3.
If a small number precedes a larger number in Roman numerals, we subtract the smaller number from the larger number. For example, IX → X - I → 10 - 1 = 9.
Symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we don't write VV for 10; instead, we use X.
Let’s learn how to write 964 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 964 in Roman numerals using the expansion method.
To write 964 in Roman numerals, follow the steps:
Step 1: Break the number based on place value: hundreds, tens, and ones. For 964, we write it as 900 + 60 + 4.
Step 2: Convert the numbers into Roman numerals.
Step 3: Combine the Roman numerals together. Therefore, 964 in Roman numerals is CM (900) + LX (60) + IV (4) = CMLXIV.
When writing a large number in Roman numerals, we group the number. To write 964 in Roman numerals, we group 964 as 900 + 60 + 4.
So, 964 is written as CMLXIV in Roman numerals.
Calculate the sum of CMLXIV and XXXVI.
A historian discovers a document that mentions CMLXIV soldiers were sent into battle. If each legion consisted of CX soldiers, how many legions were there?
A treasure chest contains CMLXIV gold coins. If a pirate crew of XLVIII members divides the coins equally, how many coins does each pirate receive?
A marathon race covers a distance of CMLXIV miles, but a runner only completes DCC miles. How many miles did the runner not complete?
Convert the total number of CMLXIV days into Roman numerals after adding LXXXIV days to it.
