Roman numerals are the 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.

What is 20000 in Roman Numerals?

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 XX with a line over it to represent 20000, indicating that the number is multiplied by 1000. Let’s learn more about Roman numerals and how we write them.

Basic Rules for 20000 in Roman Numerals

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.

 

Rule 1: Addition Method

The addition method is used when the smaller number is placed after the larger number, then it is the addition method. For example, VI → V + I → 5 + 1 = 6

 

Rule 2: Repetition Method

To write a large number, there are certain Roman Numerals that can be repeated up to three times. III → 3.

 

Rule 3: Subtraction Method

If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the large number; it is a subtraction method. For example, IV → V - I → 5 - 1 = 4

 

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 for 8, we write VIII, not IIIIIIII.

How to Write 20000 in Roman Numerals

Let’s now learn how to write 20000 in Roman Numerals. Follow these methods to write the number in Roman Numerals.

  • By Expansion Method
  • By Grouping Method

20000 in Roman Numeral by Expansion Method

In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 20000 in Roman numerals using the expansion method. To write 20000 in Roman Numerals, follow these steps:

 

Step 1: Break the number based on its place value. The place values are ones, tens, hundreds, thousands, etc. For 20000, we represent it as 20 × 1000.

 

Step 2: Convert the number into Roman Numerals.

  • 20 in Roman Numeral — XX

 

  • 1000 in Roman Numeral — M (with a line over XX to indicate multiplication by 1000)

 

Step 3: Combine the Roman Numerals together. Therefore, 20000 in Roman Numeral is XX (20) with a line over it indicating 20000.

20000 in Roman Numeral by Grouping Method

When writing a large number into Roman Numeral, we group the number. To write 20000 in Roman Numeral, we group 20000 as 20 × 1000.

  • 20 in Roman Numeral — XX

 

  • 1000 in Roman Numeral — M (with a line over XX to indicate multiplication by 1000)

So, 20000 is written as XX with a line over it in Roman Numerals.

Important Glossaries for 20000 in Roman Numerals

  • Addition rule: The addition method is used when a large number is followed by a smaller numeral; here, the values are added. For example, VI = V + I = 5 + 1 = 6.

 

  • Grouping method: Here, the given numbers are grouped based on their place value and then we convert each group into its Roman numerals. For example, 20000 = 20 × 1000 = XX (with a line over it).

 

  • Repetition rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated only up to three times. For example, III = 3 (I is repeated three times to represent the number 3).

 

  • Multiplication by 1000: A line over a numeral indicates multiplication by 1000, which is essential for representing large numbers.

 

  • Subtraction rule: If a smaller numeral precedes a larger one, it is subtracted. For example, IV = 5 - 1 = 4.
