MMMCMLXXXIX
3,989 in Roman numerals is MMMCMLXXXIX.

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 3,989:

1. MMM = 1,000 + 1,000 + 1,000 = 3,000 → M repeated 3 times.

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

3. L = 50 → represents tens.

4. XXX = 10 + 10 + 10 = 30 → X repeated 3 times.

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

So, 3,000 + 900 + 50 + 30 + 9 = 3,989, or MMMCMLXXXIX in Roman numeral form.
