MCMLXXX Roman Numerals
MCMLXXX Roman Numerals can be written as numbers by combining the transformed roman numerals i.e. MCMLXXX = M + CM + LXXX = 1000 + 900 + 80 = 1980. The higher roman numerals precede the lower numerals resulting in the correct translation of MCMLXXX Roman Numerals. In this article, we will explain how to convert MCMLXXX Roman numerals in the correct number translation.
 MCMLXXX = M + CM + LXXX
 MCMLXXX = 1000 + 900 + 80
 MCMLXXX = 1980
How to Write MCMLXXX Roman Numerals?
The numerical value of MCMLXXX Roman Numerals can be obtained by using any of the two methods given below:
Method 1: In this method, we break the roman numerals into single letters, write the numerical value of each letter and add/subtract them.
 MCMLXXX = M + (M  C) + L + X + X + X = 1000 + (1000  100) + 50 + 10 + 10 + 10 = 1980
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 MCMLXXX = M + CM + LXXX = 1000 + 900 + 80 = 1980
Therefore, the numerical value of MCMLXXX roman numerals is 1980.

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: MD, M > D, so MD = M + D = 1000 + 500 = 1500
 When a smaller letter precedes a bigger letter, the letters are subtracted. For example: CD, C < D, so CD = D  C = 500  100 = 400
 When a letter is repeated 2 or 3 times, they get added. For example: MMM = M + M + M = 1000 + 1000 + 1000 = 3000
 The same letter cannot be used more than three times in succession.
Numbers Related to MCMLXXX Roman Numerals
Roman numerals were used in ancient Rome and utilized combinations of letters using the Latin alphabets I, V, X, L, C, D, and M. It may seem different than numbers, but they are similar. For example, MCMLXXX Roman numerals are equivalent to the number 1980. The roman numerals related to MCMLXXX are given below:
 MCMLXXX = 1000 + 900 + 80 = 1980
 MCMLXXXI = 1000 + 900 + 80 + 1 = 1981
 MCMLXXXII = 1000 + 900 + 80 + 2 = 1982
 MCMLXXXIII = 1000 + 900 + 80 + 3 = 1983
 MCMLXXXIV = 1000 + 900 + 80 + 4 = 1984
 MCMLXXXV = 1000 + 900 + 80 + 5 = 1985
 MCMLXXXVI = 1000 + 900 + 80 + 6 = 1986
 MCMLXXXVII = 1000 + 900 + 80 + 7 = 1987
 MCMLXXXVIII = 1000 + 900 + 80 + 8 = 1988
 MCMLXXXIX = 1000 + 900 + 80 + 9 = 1989
MCMLXXX Roman Numerals Examples

Example 1: Evaluate the following expression: MCMLXXX  LXIV + I.
Solution:
MCMLXXX = 1980, LXIV = 64, and I = 1
⇒ MCMLXXX  LXIV + I = 1980  64 + 1 = 1917
⇒ The difference is 1917, which can be written as MCMXVII. 
Example 2: Find the Difference Between MCMLXXX and MCDLXXVII.
Solution:
Roman Numeral MCMLXXX is equal to 1980 and MCDLXXVII is 1477.
Now, MCMLXXX  MCDLXXVII = 1980  1477 = 503
Since, 503 = DIII
Therefore, MCMLXXX  MCDLXXVII = DIII 
Example 4: Find the Sum of DCCCXCIV and MCMLXXX Roman Numerals.
Solution:
DCCCXCIV = 800 + 90 + 4 = 894 and MCMLXXX = 1000 + 900 + 80 = 1980
Now, DCCCXCIV + MCMLXXX = 894 + 1980 = 2874
Since, MMDCCCLXXIV = 2000 + 800 + 70 + 4 = 2874
Therefore, the sum of DCCCXCIV and MCMLXXX roman numerals is MMDCCCLXXIV
