35 in Roman Numeral

Professor Greenline Explaining Math Concepts

In roman numerals, we represent 35 as XXXV. Here, X stands for 10 and is repeated thrice (XXX) and V stands for 5. You must have seen in movie titles, for sequels we use roman numerals. To make 35, we use three X’s for 30 (since 10 + 10 + 10 = 30) and one ‘V’ for 5.

What is 35 in Roman Numerals?

The number 35 in Roman numerals is written as XXXV. In this system, X represents 10 and V represents 5. When you put three X's together (XXX), it means you add 10 three times, which equals 30. Then, you add V (5) to that total.

 

So, XXXV represents the number 35 in Roman numerals.

 

35=ⅩⅩⅩⅤ

Professor Greenline from BrightChamps

Basic Rules for Finding XXXV in Roman Numeral

Rule 1: Addition Rule


In this method, we add the larger values which follow the smaller values in Roman numerals. 


Ⅹ + Ⅴ = ⅩⅤ    or    10 + 5 = 15


Rule 2: Repetition Rule


In this rule, the numbers repeat themselves to get the desired number, but the numbers cannot be repeated    more than thrice.


ⅩⅩ is 20


ⅩⅩⅩ is 30


Rule 3: Subtraction Rule


In this combination, In this rule, to find the difference, the greater number is written after the smaller number, the smaller number is subtracted from the greater one.


X - Ⅰ = Ⅸ    or    10 - 1 = 9


Rule 4: Limitation Rule

 


Roman numerals cannot be repeated more than thrice. This limitation cannot be used for number 4(IIII) and so on.

How to write XXXV in Roman Numeral

In roman numerals, we write 35 as XXXV.to get the desired number, we use subtraction and addition rule and combine them. We write roman numerals in methods explained below:

 

  • Expansion method

 

  • Grouping method
     
Professor Greenline from BrightChamps

35 in Roman Numeral by Expansion Method

This method includes parting down numbers based on their place values like thousands, a hundred, tens, and ones respectively. Every place value is written in the form of roman numerals.


This method works as shown below:

 

  • Expand and part down the numbers into place values.

 

  • Change the place values of numbers into roman numerals.

 

  • Join the roman numerals to get the desired value.

 

So, when you combine them, 35 in the Roman Numeral is written as XXXV.

 

Example: 

 

1. LXXXV:


L=50


XXX=30


V=5


Adding, 50+30+5=85, LXXXV.

 

Professor Greenline from BrightChamps

35 in Roman Numeral by Grouping Method

This method involves breakdown of large numerals into small parts based on their Roman numeral values. This method works as follows:

 

  • Identify symbols: Look for roman numerals that should be added or subtracted together according to addition and subtraction rules, as discussed.

 

  • Breaking down larger numbers into smaller ones.

 

  • Add or subtract values of the smaller numerals.

 

  • So, you can group three 10s as XXX and add a V to write 35 as XXXV.

 

Example:


1. XCIX


X→10


C→100


IX→9


Add: (100-10)+9=99.

 

2. CXLIX


C→100


XL→50-10=40


IX→9


Add: 100+40+9=149.

Mistake 1

 Unnecessary repetition of numerals 
 

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Students tend to repeat numbers unnecessarily, instead of XXXV they write XXVVV which is a quite longer combination. The Roman numeral for 35 is written as "XXXV" because it efficiently combines three X's (30) and one V (5). Using a longer format like XXVVV would be cumbersome.
