Roman Numeral
MCMXCIX
1,999 in Roman numerals is MCMXCIX.

Roman numerals use seven basic symbols: I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1,000. The general rule is: reading left to right, values in descending order add up. When a smaller symbol comes before a larger one, it subtracts (e.g., IV = 4), which happens in this case.

Step-by-step conversion of 1,999:

1. M = 1,000 → represents thousands.

2. CM = 1000 - 100 = 900 → subtraction rule used.

3. XC = 100 - 10 = 90 → subtraction rule used.

4. IX = 10 - 1 = 9 → subtraction rule used.

So, 1,000 + 900 + 90 + 9 = 1,999, or MCMXCIX in Roman numeral form.
