To determine the value of the Roman numeral XIII, you can break it down into its individual components:
- X = 10
- X = 10
- I = 1
- I = 1
Now, you can add these values together:
10 (from the first X) + 10 (from the second X) + 1 (from the first I) + 1 (from the second I) = 10 + 10 + 1 + 1 = 12.
So, the value of the Roman numeral XIII is 13.
