MMMCMLXXX
3,980 in Roman numerals is MMMCMLXXX.

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 3,980:

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.

So, 3,000 + 900 + 50 + 30 = 3,980, or MMMCMLXXX in Roman numeral form.
