MDIX Roman Numerals
MDIX Roman Numerals can be written as numbers by combining the transformed roman numerals i.e. MDIX = M + D + IX = 1000 + 500 + 9 = 1509. The higher roman numerals precede the lower numerals resulting in the correct translation of MDIX Roman Numerals. In this article, we will explain how to convert MDIX Roman numerals in the correct number translation.
 MDIX = M + D + (X  I)
 MDIX = 1000 + 500 + (10  1)
 MDIX = 1509
How to Write MDIX Roman Numerals?
The numerical value of MDIX 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.
 MDIX = M + D + (X  I) = 1000 + 500 + (10  1) = 1509
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 MDIX = M + D + IX = 1000 + 500 + 9 = 1509
Therefore, the numerical value of MDIX roman numerals is 1509.

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: LX, L > X, so LX = L + X = 50 + 10 = 60
 When a smaller letter precedes a bigger letter, the letters are subtracted. For example: XC, X < C, so XC = C  X = 100  10 = 90
 When a letter is repeated 2 or 3 times, they get added. For example: MMM = M + M + M = 1000 + 1000 + 1000 = 3000
 The same letter cannot be used more than three times in succession.
Numbers Related to MDIX Roman Numerals
Roman numerals were used in ancient Rome and utilized combinations of letters using the Latin alphabets I, V, X, L, C, D, and M. It may seem different than numbers, but they are similar. For example, MDIX Roman numerals are equivalent to the number 1509. The roman numerals related to MDIX are given below:
 MD = 1000 + 500 = 1500
 MDI = 1000 + 500 + 1 = 1501
 MDII = 1000 + 500 + 2 = 1502
 MDIII = 1000 + 500 + 3 = 1503
 MDIV = 1000 + 500 + 4 = 1504
 MDV = 1000 + 500 + 5 = 1505
 MDVI = 1000 + 500 + 6 = 1506
 MDVII = 1000 + 500 + 7 = 1507
 MDVIII = 1000 + 500 + 8 = 1508
 MDIX = 1000 + 500 + 9 = 1509
MDIX Roman Numerals Examples

Example 1: Find the Difference Between MDIX and CCCLI.
Solution:
Roman Numeral MDIX is equal to 1509 and CCCLI is 351.
Now, MDIX  CCCLI = 1509  351 = 1158
Since, 1158 = MCLVIII
Therefore, MDIX  CCCLI = MCLVIII 
Example 3: Evaluate the following expression: MDIX  XCIX + XVI.
Solution:
MDIX = 1509, XCIX = 99, and XVI = 16
⇒ MDIX  XCIX + XVI = 1509  99 + 16 = 1426
⇒ The difference is 1426, which can be written as MCDXXVI. 
Example 4: Find the Sum of MMCCLXXXI and MDIX Roman Numerals.
Solution:
MMCCLXXXI = 2000 + 200 + 80 + 1 = 2281 and MDIX = 1000 + 500 + 9 = 1509
Now, MMCCLXXXI + MDIX = 2281 + 1509 = 3790
Since, MMMDCCXC = 3000 + 700 + 90 = 3790
Therefore, the sum of MMCCLXXXI and MDIX roman numerals is MMMDCCXC
