What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: MX, M > X, so MX = M + X = 1000 + 10 = 1010
 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.

LXVI Roman Numerals Examples

Example 1: Find the Product of Roman Numerals LXVI and XXIV.
Solution:
LXVI = 60 + 6 = 66 and XXIV = 20 + 4 = 24
Now, LXVI × XXIV = 66 × 24 = 1584
Since, MDLXXXIV = 1000 + 500 + 80 + 4 = 1584
Therefore, LXVI × XXIV = MDLXXXIV 
Example 2: Find the Sum of MMMCCCXII and LXVI Roman Numerals.
Solution:
MMMCCCXII = 3000 + 300 + 10 + 2 = 3312 and LXVI = 60 + 6 = 66
Now, MMMCCCXII + LXVI = 3312 + 66 = 3378
Since, MMMCCCLXXVIII = 3000 + 300 + 70 + 8 = 3378
Therefore, the sum of MMMCCCXII and LXVI roman numerals is MMMCCCLXXVIII 
Example 4: Find the Difference Between LXVI and L.
Solution:
Roman Numeral LXVI is equal to 66 and L is 50.
Now, LXVI  L = 66  50 = 16
