MMCD
2,400 in Roman numerals is MMCD.

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 2,400:

1. MM = 1,000 + 1,000 = 2,000 → M repeated 2 times.

2. CD = 500 - 100 = 400 → subtraction rule used.

So, 2,000 + 400 = 2,400, or MMCD in Roman numeral form.
