1980 = MCMLXXX

For Roman numerals

M = 1000

D = 500

C = 100

L = 50

X = 10

V = 5

I = 1

The highest value is always placed to the left, except for subtraction. Followed by lower values.

M = 1000

CM = 1000 - 100 = 900 (Note what has been done here).

L = 50

XXX = 10 + 10 + 10 = 30

Adding 1000 + 900 + 50 + 30 = 1980
