LXXXVII
87 in Roman numerals is LXXXVII.

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 does not happen in this case.

Step-by-step conversion of 87:

1. L = 50 → represents tens.

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

3. V = 5 → represents units.

4. II = 1 + 1 = 2 → I repeated 2 times.

So, 50 + 30 + 5 + 2 = 87, or LXXXVII in Roman numeral form.
