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. Early 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 DCCXXXVII to represent 737, where D is 500, CC is 200, XXX is 30, and VII is 7.
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, DCCXXXVII → D + CC + XXX + VII → 500 + 200 + 30 + 7 = 737
To write a large number, there are certain Roman Numerals that can be repeated three times. For example, CCC → 300.
If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the large number. For example, XC → X - C → 100 - 10 = 90
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 737 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 737 in Roman numerals using the expansion method. To write 737 in Roman Numerals, follow these steps:
Step 1: Break the number based on the place value. Place value includes ones, tens, hundreds, etc. For 737, we write it as 700 + 30 + 7.
Step 2: Convert the number into Roman Numerals
Step 3: Combine the Roman Numerals together. Therefore, 737 in Roman Numerals is DCC (700) + XXX (30) + VII (7) = DCCXXXVII
When writing a large number into Roman Numerals, we group the number. To write 737 in Roman Numerals, we group 737 as 700 + 30 + 7.
So, 737 is written as DCCXXXVII in Roman Numerals.
Addition rule: The addition method is used when a large number is followed by a smaller numeral, where the values are added. For example, DCCXXXVII = D + CC + XXX + VII = 500 + 200 + 30 + 7 = 737. Grouping method: Here, the given numbers are grouped based on their place value and then converted into their Roman numerals. For example, 737 = 700 + 30 + 7 = DCCXXXVII. Repetition rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated only up to three times. For example, XXX = 30 (X is repeated three times to represent the number 30). Subtraction rule: If a smaller numeral precedes a larger one, it is subtracted. For example, IX = X - I = 10 - 1 = 9. Roman numeral symbols: The set of symbols used in Roman numerals includes I (1), V (5), X (10), L (50), C (100), D (500), and M (1000).
