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, often 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 fingers, sticks, bones, etc., to count. As life became more 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 DCCCLXXV to represent 875, where D is 500, CCC is 300, L is 50, XX is 20, and V is 5. 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, DCCCLXXV → D + CCC + L + XX + V → 500 + 300 + 50 + 20 + 5 = 875
To write a large number, certain Roman Numerals can be repeated up to three times. For example, CCC → 300.
If a small number precedes a large number in Roman Numerals, we subtract the smaller number from the large number. This is the subtraction method. For example, IV → V - I → 5 - 1 = 4
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 LL for 100; instead, we use C.
Let’s now learn how to write 875 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 875 in Roman numerals using the expansion method. To write 875 in Roman Numerals, follow the steps:
Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc. For 875, we write it as 500 + 300 + 50 + 20 + 5.
Step 2: Convert the numbers into Roman Numerals.
Step 3: Combine the Roman Numerals together. Therefore, 875 in Roman Numeral is D (500) + CCC (300) + L (50) + XX (20) + V (5) = DCCCLXXV
When writing a large number in Roman Numeral, we group the number. To write 875 in Roman Numeral, we group 875 as 500 + 300 + 50 + 20 + 5
So, 875 is written as DCCCLXXV in Roman Numerals.
