CMIX Roman Numerals
CMIX Roman Numerals can be written as numbers by combining the transformed roman numerals i.e. CMIX = (M  C) + (X  I) = (1000  100) + (10  1) = 909. The higher roman numerals precede the lower numerals resulting in the correct translation of CMIX Roman Numerals. In this article, we will explain how to convert CMIX Roman numerals in the correct number translation.
 CMIX = (M  C) + (X  I)
 CMIX = (1000  100) + (10  1)
 CMIX = 909
How to Write CMIX Roman Numerals?
The numerical value of CMIX 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.
 CMIX = (M  C) + (X  I) = (1000  100) + (10  1) = 909
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 CMIX = CM + IX = 900 + 9 = 909
Therefore, the numerical value of CMIX roman numerals is 909.

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: LI, L > I, so LI = L + I = 50 + 1 = 51
 When a smaller letter precedes a bigger letter, the letters are subtracted. For example: CD, C < D, so CD = D  C = 500  100 = 400
 When a letter is repeated 2 or 3 times, they get added. For example: CCC = C + C + C = 100 + 100 + 100 = 300
 The same letter cannot be used more than three times in succession.

CMIX Roman Numerals Examples

Example 2: Find the Sum of MMDCXXXVII and CMIX Roman Numerals.
Solution:
MMDCXXXVII = 2000 + 600 + 30 + 7 = 2637 and CMIX = 900 + 9 = 909
Now, MMDCXXXVII + CMIX = 2637 + 909 = 3546
Since, MMMDXLVI = 3000 + 500 + 40 + 6 = 3546
Therefore, the sum of MMDCXXXVII and CMIX roman numerals is MMMDXLVI 
Example 3: Find the Difference Between CMIX and DCCLXXXVIII.
Solution:
Roman Numeral CMIX is equal to 909 and DCCLXXXVIII is 788.
Now, CMIX  DCCLXXXVIII = 909  788 = 121
Since, 121 = CXXI
Therefore, CMIX  DCCLXXXVIII = CXXI 
Example 4: Find the Product of Roman Numerals CMIX and I.
Solution:
CMIX = 900 + 9 = 909 and I = 1
Now, CMIX × I = 909 × 1 = 909
Since, CMIX = 900 + 9 = 909
Therefore, CMIX × I = CMIX
FAQs on CMIX Roman Numerals
