CIX Roman Numerals
CIX Roman Numerals can be written as numbers by combining the transformed roman numerals i.e. CIX = C + IX = 100 + 9 = 109. The higher roman numerals precede the lower numerals resulting in the correct translation of CIX Roman Numerals. In this article, we will explain how to convert CIX Roman numerals in the correct number translation.
 CIX = C + (X  I)
 CIX = 100 + (10  1)
 CIX = 109
How to Write CIX Roman Numerals?
The numerical value of CIX 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.
 CIX = C + (X  I) = 100 + (10  1) = 109
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 CIX = C + IX = 100 + 9 = 109
Therefore, the numerical value of CIX roman numerals is 109.

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: DI, D > I, so DI = D + I = 500 + 1 = 501
 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: CC = C + C = 100 + 100 = 200
 The same letter cannot be used more than three times in succession.

CIX Roman Numerals Examples

Example 2: Find the Difference Between CIX and LVII.
Solution:
Roman Numeral CIX is equal to 109 and LVII is 57.
Now, CIX  LVII = 109  57 = 52
Since, 52 = LII
Therefore, CIX  LVII = LII 
Example 3: Find the Sum of MMLXXVII and CIX Roman Numerals.
Solution:
MMLXXVII = 2000 + 70 + 7 = 2077 and CIX = 100 + 9 = 109
Now, MMLXXVII + CIX = 2077 + 109 = 2186
Since, MMCLXXXVI = 2000 + 100 + 80 + 6 = 2186
Therefore, the sum of MMLXXVII and CIX roman numerals is MMCLXXXVI 
Example 4: Find the Product of Roman Numerals CIX and II.
Solution:
CIX = 100 + 9 = 109 and II = 2
Now, CIX × II = 109 × 2 = 218
Since, CCXVIII = 200 + 10 + 8 = 218
Therefore, CIX × II = CCXVIII
