Roman numerals are a way of expressing numbers using symbols: I, V, X, L, C, D, and M. Roman numerals are used in royal titles, book names, sequences, and so on. Here we will be discussing Roman numerals, rules, and examples.
Royal titles, such as Henry I, Henry II, and so on, use Roman numerals. 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 MCMLXIV to represent 1964. 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 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, and for 8, we write VIII, not IIIIIIII.
Let’s now learn how to write 1964 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 1964 in Roman numerals using the expansion method. To write 1964 in Roman numerals, follow the steps:
Step 1: Break the number based on the place value. Place value includes ones, tens, hundreds, etc. For 1964, we write it as 1000 + 900 + 60 + 4
Step 2: Converting the numbers into Roman numerals
Step 3: Combining the Roman numerals together. Therefore, 1964 in Roman numerals is M (1000) + CM (900) + LX (60) + IV (4) = MCMLXIV
When writing a large number into Roman numerals, we group the number. To write 1964 in Roman numerals, we group it as 1000 + 900 + 60 + 4
So, 1964 is written as MCMLXIV in Roman numerals.
