MCMLXXI in Arabic numerals is 1,971.

Roman numerals use seven basic symbols: I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1000. When reading from left to right, if a smaller symbol comes before a larger one, it subtracts (e.g., IV = 4). Otherwise, symbols add up, which happens in this case.

Step-by-step conversion of MCMLXXI:

1. M = 1,000 → added as normal value.

2. C = 100 → subtracted because it comes before a larger numeral (M = 1,000).

3. M = 1,000 → added as normal value.

4. L = 50 → added as normal value.

5. X = 10 → added as normal value.

6. X = 10 → added as normal value.

7. I = 1 → added as normal value.

Final result: +1000 -100 +1000 +50 +10 +10 +1 = 1,971 → 1971.
