Answers
Answer:
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,
MCMLXXIX = M + CM + LXX + IX = 1000 + 900 + 70 + 9 = 1979
Therefore, the numerical value of MCMLXXIX roman numerals is 1979.

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.
