What does roman numeral MCD mean?

Answer 1

MCD = 1,400

M = 1,000

C = 100

D = 500

Because the C is less than D, and because it is to the left of the D, one must subtract the values:

CD = 500 - 100 = 400

Therefore:

MCD = 1,000 + 400 = 1,400

Answer 2

MCD = 1,400 M = 1,000 C = 100 D = 500 Because the C is less than D, and because it is to the left of the D, one must subtract the values: CD = 500 - 100 = 400 Therefore: MCD = 1,000 + 400 = 1,400
