Roman Numeral
MCCXLIII
1,243 in Roman numerals is MCCXLIII.

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 1,243:

1. M = 1,000 → represents thousands.

2. CC = 100 + 100 = 200 → C repeated 2 times.

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

4. III = 1 + 1 + 1 = 3 → I repeated 3 times.

So, 1,000 + 200 + 40 + 3 = 1,243, or MCCXLIII in Roman numeral form.
