Understanding Roman Numerals
Roman numerals are a numeral system originating from ancient Rome, using combinations of letters from the Latin alphabet. The primary letters used are:
- I (1)
- V (5)
- X (10)
- L (50)
- C (100)
- D (500)
- M (1000)
Identifying M
The letter "M" in Roman numerals represents the value 1000. Therefore, to find the numeral that comes just before "M," we need to identify the numeral that equals 999.
Analyzing the Options
Let's evaluate the given options:
- DCMXCIX:
- D (500) + C (100) + M (1000) + X (10) + C (100) + I (1) + X (10) = 999 (Incorrect)
- CMXCIX:
- C (100) + M (1000) + X (10) + C (100) + I (1) + X (10) = 999 (Correct)
- CMXCV:
- C (100) + M (1000) + X (10) + C (100) + V (5) = 995 (Incorrect)
- CMIX:
- C (100) + M (1000) + I (1) + X (10) = 911 (Incorrect)
Conclusion
The correct answer is option 'B' (CMXCIX), which represents 999. Therefore, CMXCIX is indeed the numeral that comes just before M (1000) in Roman numerals.
