How to Write 10 in Roman Numerals?

10 in Roman numerals is represented as ‘X’. Roman numerals are part of an ancient number system, created by the Greeks using specific letters from the Latin alphabet to denote values. Each of these letters represents a fixed number, and by combining them, we can form different numbers. These numerals were used in daily transactions, trade, record keeping, and for event tracking. We can see them even today on clocks, books, film titles, and documents.

How to Write 10 in Roman Numerals?

Writing 10 in Roman numerals involves representing 10 using the fundamental Latin symbol X.  

10 is formed by using the symbol ‘X’ and its multiples like 20 and 30 are represented as its repretition as XX and XXX.

 

Basic Rules of Roman Numerals

• A symbol is added to itself if repeated.

Example: II = 2, XX = 20, XXX = 30

 

• A symbol can be repeated only 3 times.

  Example: XXX = 30, CC = 200

 

• Symbols V (5), L (50), and D (500) are never repeated.

 

• If a smaller symbol comes after a bigger one, we add.

  Example: VI = 5 + 1 = 6

 

• If a smaller symbol precedes a larger one, we subtract.

  Example: IX = 10 – 1 =19

 

• Symbols V, L, and D are never subtracted.

 

• I can be subtracted only from V and X.

 

• X can be subtracted only from L, C, and M.

 

Solved Examples on Roman Numerals

Example 1:  Explain the difference between X (10) and IX (9) in Roman numerals.

Solution:

We know that X in Roman numerals represents 10 and IX represents 9.

To understand the difference, we have to understand how IX is written:

10–1 = 9

Therefore, 9 in Roman numerals is IX.

 

Example 2: What should be subtracted from X to obtain IX?

Solution:

We know that 10 in Roman numerals is X and I is 1.

So, we need to subtract 1 from 10 to get 9:

10–1 = 9

As 1 in Roman numerals is I.

Therefore, X–I = IX.

 

Example 3: How to write 20 in Roman numerals.

Solution:

We know that X in Roman numerals is 10, and as we know, the symbol can be repeated only 2 times.

To find the 30 in Roman numerals, we add:

10+10 = 20

X+X= XX

Therefore, 20 in Roman numerals is represented as XX.
