Convert 456 to a Roman numeral
Roman Numeral Values are:
I = 1, V = 5, X = 10
L = 50, C = 100, D = 500,
M = 1,000
We start with a total letter value of 456
We want 3 or less of a letter
We need to subtract
Write the next letter of D in front of C
+ CD = CD
1 letter C and 1 letter D gives us:
500 - 100 = 400
Total: 456 - 400 = 56
CD + L = CDL
1 of the letter L gives us
1 * 50 = 50
Total: 56 - 50 = 6
CDL + V = CDLV
1 of the letter V gives us
1 * 5 = 5
Total: 6 - 5 = 1
CDLV + I = CDLVI
1 of the letter I gives us
1 * 1 = 1
Total: 1 - 1 = 0
