The higher roman numerals precede the lower numerals resulting in the correct translation of MCMLXXIX Roman Numerals. In this article, we will explain how to convert MCMLXXIX Roman numerals in the correct number translation.
 MCMLXXIX = M + CM + LXX + IX

How to Write MCMLXXIX Roman Numerals?
The numerical value of MCMLXXIX 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.
 MCMLXXIX = M + (M  C) + L + X + X + (X  I) = 1000 + (1000  100) + 50 + 10 + 10 + (10  1) = 1979
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: MC, M > C, so MC = M + C = 1000 + 100 = 1100
 When a smaller letter precedes a bigger letter, the letters are subtracted. For example: XC, X < C, so XC = C  X = 100  10 = 90
 When a letter is repeated 2 or 3 times, they get added. For example: CC = C + C = 100 + 100 = 200
 The same letter cannot be used more than three times in succession.

 MCMLXXI = 1000 + 900 + 70 + 1 = 1971
 MCMLXXII = 1000 + 900 + 70 + 2 = 1972
 MCMLXXIII = 1000 + 900 + 70 + 3 = 1973
 MCMLXXIV = 1000 + 900 + 70 + 4 = 1974
 MCMLXXV = 1000 + 900 + 70 + 5 = 1975
 MCMLXXVI = 1000 + 900 + 70 + 6 = 1976
 MCMLXXVII = 1000 + 900 + 70 + 7 = 1977
 MCMLXXVIII = 1000 + 900 + 70 + 8 = 1978
 MCMLXXIX = 1000 + 900 + 70 + 9 = 1979
MCMLXXIX Roman Numerals Examples

Example 1: Find the Difference Between MCMLXXIX and DCXIII.
Solution:
Roman Numeral MCMLXXIX is equal to 1979 and DCXIII is 613.
Now, MCMLXXIX  DCXIII = 1979  613 = 1366
Since, 1366 = MCCCLXVI
Therefore, MCMLXXIX  DCXIII = MCCCLXVI 
Example 3: Evaluate the following expression: MCMLXXIX  LXXXIX + VIII.
Solution:
MCMLXXIX = 1979, LXXXIX = 89, and VIII = 8
⇒ MCMLXXIX  LXXXIX + VIII = 1979  89 + 8 = 1898
⇒ The difference is 1898, which can be written as MDCCCXCVIII. 
Example 4: Find the Sum of MDCXXIV and MCMLXXIX Roman Numerals.
Solution:
MDCXXIV = 1000 + 600 + 20 + 4 = 1624 and MCMLXXIX = 1000 + 900 + 70 + 9 = 1979
Now, MDCXXIV + MCMLXXIX = 1624 + 1979 = 3603
Since, MMMDCIII = 3000 + 600 + 3 = 3603
Therefore, the sum of MDCXXIV and MCMLXXIX roman numerals is MMMDCIII
