The Roman numeral “CDLXI” represents the number 461 in the decimal (or base-10) system. Here’s how it breaks down:

- CD = 400 (C is 100, and D is 500, but when a smaller numeral precedes a larger one, you subtract the smaller from the larger, so CD is 500 – 100)
- LX = 60 (L is 50, and X is 10, added together because the smaller numeral follows the larger one)
- I = 1

So, when you add these together, 400 + 60 + 1 = 461.
