XXV + XX. Give your answer in Roman numerals. Guys, please help.
The Correct Answer and Explanation is:
To solve the problem XXV + XX in Roman numerals, we first need to convert the Roman numerals into regular integers, perform the addition, and then convert the result back into Roman numerals.
Step 1: Convert the Roman Numerals to Integers
- XXV: The Roman numeral XXV is made up of:
- XX = 10 + 10 = 20
- V = 5
So, XXV = 20 + 5 = 25.
- XX: The Roman numeral XX represents:
- XX = 10 + 10 = 20.
Step 2: Add the Integers
Now, add the two integers:
- 25 + 20 = 45
Step 3: Convert the Result Back to Roman Numerals
To convert 45 back into Roman numerals:
- 40 is represented as XL (50 – 10), and
- 5 is represented as V.
So, 45 in Roman numerals is XLV.
Final Answer:
The sum of XXV + XX in Roman numerals is XLV.
Explanation:
Roman numerals are a numeral system used in ancient Rome. They use combinations of letters from the Latin alphabet: I, V, X, L, C, D, M. The value of Roman numerals is determined by the letter or letters used. The key rules are:
- When a smaller numeral comes before a larger numeral, you subtract (e.g., IV for 4).
- When a smaller or equal numeral comes after a larger one, you add (e.g., VI for 6).
The process of converting Roman numerals to integers involves adding and subtracting according to these rules. Similarly, to convert an integer into Roman numerals, we break the number down into components that can be represented by Roman numerals, such as tens, fifties, and so on.
