MMXLV
2,045 in Roman numerals is MMXLV.

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 2,045:

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

2. XL = 50 - 10 = 40 → subtraction rule used.

3. V = 5 → represents units.

So, 2,000 + 40 + 5 = 2,045, or MMXLV in Roman numeral form.
