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 symbols like I and II that represent Roman numerals. Earlier people used physical items like fingers, sticks, and bones for counting. As 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 CMLIII to represent 953, where CM is 900, L is 50, and III is 3. 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, LIII → L + III → 50 + 3 = 53.
To write a large number, there are certain Roman numerals that can be repeated three times. III → 3.
If a small number is placed before a large number in Roman numerals, we subtract the smaller number from the large number. For example, CM → M - C → 1000 - 100 = 900.
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 DDD for 1500; instead, we use MD for 1500.
Let’s now learn how to write 953 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 953 in Roman numerals using the expansion method.
To write 953 in Roman numerals, follow these steps:
Step 1: Break down the number based on place value—ones, tens, hundreds, etc. For 953, we write it as 900 + 50 + 3.
Step 2: Convert the number into Roman numerals.
Step 3: Combine the Roman numerals together. Therefore, 953 in Roman numerals is CM (900) + L (50) + III (3) = CMLIII.
When writing a large number into Roman numerals, we group the number. To write 953 in Roman numerals, we group 953 as 900 + 50 + 3.
So, 953 is written as CMLIII in Roman numerals.
