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.
Earlier, 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 DCCCXCIX to represent 899. Here DCCC is 800, XC is 90, and IX is 9. 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 three times. III → 3.
If a small number precedes a large number in Roman Numerals, we subtract the smaller number from the larger one. For example, IX → X - I → 10 - 1 = 9
Rule 4: Limitation Rule
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 8 is written as VIII, not IIIIIIII.
Let’s now learn how to write 899 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 899 in Roman numerals using the expansion method. To write 899 in Roman Numerals, follow the steps:
Step 1: Break the number based on the place value. Place value includes ones, tens, hundreds, etc. For 899, we write it as 800 + 90 + 9
Step 2: Converting the number into Roman Numerals
Step 3: Combine the Roman Numerals together. Therefore, 899 in Roman Numerals is DCCC (800) + XC (90) + IX (9) = DCCCXCIX
When writing a large number in Roman Numerals, we group the numbers. To write 899 in Roman Numerals, we group 899 as 800 + 90 + 9
So, 899 is written as DCCCXCIX in Roman Numerals.
Calculate the sum of DCCC and XCIX.
