What are the Basic Rules to Write Roman Numerals?

When a bigger letter precedes a smaller letter, the letters are added. For example: CI, C > I, so CI = C + I = 100 + 1 = 101
When a smaller letter precedes a bigger letter, the letters are subtracted. For example: CM, C < M, so CM = M - C = 1000 - 100 = 900
When a letter is repeated 2 or 3 times, they get added. For example: MM = M + M = 1000 + 1000 = 2000
The same letter cannot be used more than three times in succession.

Solution:
CCLXXXIII = 200 + 80 + 3 = 283 and LXXVIII = 70 + 8 = 78
Now, CCLXXXIII + LXXVIII = 283 + 78 = 361
Since, CCCLXI = 300 + 60 + 1 = 361
Therefore, the sum of CCLXXXIII and LXXVIII roman numerals is CCCLXI
Example 3: Find the Difference Between LXXVIII and XXXII.
