How to Write 7 in Roman Numerals?

To write 7 in Roman numerals, we have to first break it down as 5 + 1 + 1 and replace the digits with symbols as V + I + I to get VII.

 

Rules to Interpret Roman Numerals

• Repetition Rule: A symbol can be repeated only 3 times.
  Example: XX = 20, CC = 200

A symbol is added to itself if repeated.
Example: III = 3, XXX = 30

 

• Subtractive Rule: If a smaller symbol precedes a larger one, we subtract.
  Example: IX = 10 – 1 =19

 

• Additive Rule: If a smaller symbol comes after a bigger one, we add.
  Example: VI = 5 + 1 = 6

 

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

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

7 in Roman Numerals- Examples

Example 1:  Determine the value of 10 – 3 in Roman numerals.

Solution:

We know that 10 in Roman numerals represents as X and 3 is represents as III.

To understand the difference, we have to first subtract 3 from 10 to get 7 and understand how to represent 7 in Roman numerals: 

10 – 3 = 7

To write 7 in Roman numeral first break it into 5 + 1 + 1, i.e., V + I = I 

Therefore, X – III = VII

So, 10 – 3 in Roman numerals is VII.

 

Example 2: What should be added from V to obtain VII?

Solution:

We know that 5 in Roman numerals is V and I is 1.

So, we need to add 2 to 5 to get 7:

5 + 2 = 7

As 2 in Roman numerals is II.

Therefore, V + II = VII.

 

Example 3: What is VII + I in Roman numerals?

Solution: 

We know that VII Roman numerals is 7 and I is 1.

So, by adding 1 to 7 we get 8:

VII + I = VIII
