The higher roman numerals precede the lower numerals resulting in the correct translation of CXXXVIII Roman Numerals. In this article, we will explain how to convert CXXXVIII Roman numerals in the correct number translation.
 CXXXVIII = C + X + X + X + V + I + I + I
 CXXXVIII = 100 + 10 + 10 + 10 + 5 + 1 + 1 + 1
 CXXXVIII = 138
How to Write CXXXVIII Roman Numerals?
The numerical value of CXXXVIII 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.
 CXXXVIII = C + X + X + X + V + I + I + I = 100 + 10 + 10 + 10 + 5 + 1 + 1 + 1 = 138
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 CXXXVIII = C + XXX + VIII = 100 + 30 + 8 = 138

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: DX, D > X, so DX = D + X = 500 + 10 = 510
 When a smaller letter precedes a bigger letter, the letters are subtracted. For example: XL, X < L, so XL = L  X = 50  10 = 40
 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.

CXXXVIII Roman Numerals Examples

Example 1: Find the Sum of MMDCCCLXXII and CXXXVIII Roman Numerals.
Solution:
MMDCCCLXXII = 2000 + 800 + 70 + 2 = 2872 and CXXXVIII = 100 + 30 + 8 = 138
Now, MMDCCCLXXII + CXXXVIII = 2872 + 138 = 3010
Since, MMMX = 3000 + 10 = 3010
Therefore, the sum of MMDCCCLXXII and CXXXVIII roman numerals is MMMX 
Example 2: Find the Difference Between CXXXVIII and LXXVI.
Solution:
Roman Numeral CXXXVIII is equal to 138 and LXXVI is 76.
Now, CXXXVIII  LXXVI = 138  76 = 62
