LXVI Roman Numerals
LXVI Roman Numerals can be written as numbers by combining the transformed roman numerals i.e. LXVI = LX + VI = 60 + 6 = 66. The higher roman numerals precede the lower numerals resulting in the correct translation of LXVI Roman Numerals. In this article, we will explain how to convert LXVI Roman numerals in the correct number translation.
 LXVI = L + X + V + I
 LXVI = 50 + 10 + 5 + 1
 LXVI = 66
How to Write LXVI Roman Numerals?
The numerical value of LXVI 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.
 LXVI = L + X + V + I = 50 + 10 + 5 + 1 = 66
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 LXVI = LX + VI = 60 + 6 = 66
Therefore, the numerical value of LXVI roman numerals is 66.

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
Since, 16 = XVI
Therefore, LXVI  L = XVI
