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.

LXXVIII Roman Numerals Examples
Example 1: Find the Product of Roman Numerals LXXVIII and VI.
LXXVIII = 70 + 8 = 78 and VI = 6
Now, LXXVIII × VI = 78 × 6 = 468
Since, CDLXVIII = 400 + 60 + 8 = 468
Therefore, LXXVIII × VI = CDLXVIII
Example 2: Find the Sum of CCLXXXIII and LXXVIII Roman Numerals.
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.
Roman Numeral LXXVIII is equal to 78 and XXXII is 32.
Now, LXXVIII - XXXII = 78 - 32 = 46
Since, 46 = XLVI
Therefore, LXXVIII - XXXII = XLVI
