Letter Values are N=0, I=1, V=5, X=10, L=50, C=100, D=500, and M=1,000.

Letter 1 is D which has a numeric value of 500

We add 500 to our Roman numeral sum of 0 to get: 500 + 0 = 500

Letter 2 is C which has a numeric value of 100
Since the next letter X has a lower numeric value of 10, we assign a positive value to C
We add 100 to our Roman numeral sum of 500 to get: 100 + 500 = 600

Letter 3 is X which has a numeric value of 10
Since the next letter V has a lower numeric value of 5, we assign a positive value to X
We add 10 to our Roman numeral sum of 600 to get: 10 + 600 = 610

Letter 4 is V which has a numeric value of 5
Since the next letter I has a lower numeric value of 1, we assign a positive value to V
We add 5 to our Roman numeral sum of 610 to get: 5 + 610 = 615

Letter 5 is I which has a numeric value of 1
Since the next letter I has a lower numeric value of 1, we assign a positive value to I
We add 1 to our Roman numeral sum of 615 to get: 1 + 615 = 616

Letter 6 is I which has a numeric value of 1
Since the next letter has a lower numeric value of 0, we assign a positive value to I
We add 1 to our Roman numeral sum of 616 to get: 1 + 616 = 617

Therefore, the Roman numeral DCXVII has a numeric value of 617
