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 those names and wondered what these symbols (I and II) represented? Those are the Roman Numerals.
Earlier, people used 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.
In Roman Numerals, we use the symbol X̅ (10,000) to represent ten thousand. Therefore, for 30000, we write it as X̅ X̅ X̅. 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, XI → X + I → 10 + 1 = 11.
To write a large number, certain Roman Numerals can be repeated up to three times. For example, XXX → 30.
An overline on a Roman numeral indicates it is multiplied by 1,000. For example, X̅ represents 10,000.
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 V̅ for 5000; instead, we use V̅ is not used for 5000.
Let’s now learn how to write 30000 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 30000 in Roman numerals using the expansion method. To write 30000 in Roman Numerals, follow the steps:
Step 1: Break the number based on place value. For 30000, we write it as 10000 + 10000 + 10000.
Step 2: Converting each number into Roman Numerals
Step 3: Combine the Roman Numerals together. Therefore, 30000 in Roman Numeral is X̅ + X̅ + X̅ = X̅ X̅ X̅.
When writing a large number into Roman Numeral, we group the number. To write 30000 in Roman Numeral, we group 30000 as 10000 + 10000 + 10000.
So, 30000 is written as X̅ X̅ X̅ in Roman Numerals.
