Basic Rules of Writing 10 in 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 = 9

• 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 10 in 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:

IX = X - 1 = 10 - 1 = 9

Therefore, 10 in Roman numerals is X and 9 in Roman numerals is IX.

 

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

Solution:

We know that XII is 12 and IX is 9.

So, by subtracting 9 from 12 to get 4:

12 - 9 = 4

As 4 in Roman numerals is IV.

Therefore, we get IV Roman numerals as the result of XII - IX.

 

Example 3: How to write 20 in Roman numerals.

Solution:

In Roman numerals 10 = X, and as per Roman numeral rules a symbol can be repeated to form another number. So to write 20 we need to write 'X' two times:

10+10 = 20

X+X= XX

Therefore, 20 in Roman numerals is represented as XX.
