How to Add and Subtract Roman Numerals in Maths (with Examples)
FAQs on Roman Numerals Add and Subtract Worksheet for Class 4
1. How do you add and subtract Roman numerals?
You can add and subtract Roman numerals easily by first converting them into Hindu-Arabic numbers, performing the calculation, and then converting the result back to Roman numerals. This is the most common and accurate method taught in Class 4 maths.
- Step 1: Convert each Roman numeral in the sum to its Hindu-Arabic equivalent (e.g., XII = 12, V = 5).
- Step 2: Perform the addition or subtraction (e.g., 12 + 5 = 17).
- Step 3: Convert the final answer back into a Roman numeral (e.g., 17 = XVII).
2. What is an example of adding Roman numerals for Class 4?
A common example of adding Roman numerals for Class 4 is solving a sum like XIV + V. To solve this, you first convert the numerals, add them, and then write the answer in Roman form.
- Convert XIV to 14.
- Convert V to 5.
- Add the numbers: 14 + 5 = 19.
- Convert the result 19 back to Roman numerals, which is XIX.
Therefore, XIV + V = XIX.
3. How do you solve Roman numeral sums?
To solve Roman numeral sums, the best method is to use the conversion technique, as it prevents confusion with Roman numeral rules. This approach works for both addition and subtraction exercises.
- Convert: Change all the Roman numerals in the problem to standard numbers (e.g., XX = 20, IV = 4).
- Calculate: Perform the required operation, either addition or subtraction (e.g., 20 - 4 = 16).
- Convert Back: Change the final numerical answer back into Roman numeral format (e.g., 16 = XVI).
