Roman Numeral
DCCCXXIII
823 in Roman numerals is DCCCXXIII.

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 823:

1. D = 500 → represents hundreds.

2. CCC = 100 + 100 + 100 = 300 → C repeated 3 times.

3. XX = 10 + 10 = 20 → X repeated 2 times.

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

So, 500 + 300 + 20 + 3 = 823, or DCCCXXIII in Roman numeral form.
