CXXIII Roman Numerals
CXXIII Roman Numerals can be written as numbers by combining the transformed roman numerals i.e. CXXIII = C + XX + III = 100 + 20 + 3 = 123. The higher roman numerals precede the lower numerals resulting in the correct translation of CXXIII Roman Numerals. In this article, we will explain how to convert CXXIII Roman numerals in the correct number translation.
 CXXIII = C + XX + III
 CXXIII = 100 + 20 + 3
 CXXIII = 123
How to Write CXXIII Roman Numerals?
The numerical value of CXXIII 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.
 CXXIII = C + X + X + I + I + I = 100 + 10 + 10 + 1 + 1 + 1 = 123
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 CXXIII = C + XX + III = 100 + 20 + 3 = 123
Therefore, the numerical value of CXXIII roman numerals is 123.

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: CL, C > L, so CL = C + L = 100 + 50 = 150
 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: XX = X + X = 10 + 10 = 20
 The same letter cannot be used more than three times in succession.

CXXIII Roman Numerals Examples

Example 1: Find the Product of Roman Numerals CXXIII and IX.
Solution:
CXXIII = 100 + 20 + 3 = 123 and IX = 9
Now, CXXIII × IX = 123 × 9 = 1107
Since, MCVII = 1000 + 100 + 7 = 1107
Therefore, CXXIII × IX = MCVII 
Example 3: Find the Difference Between CXXIII and XLIX.
Solution:
Roman Numeral CXXIII is equal to 123 and XLIX is 49.
Now, CXXIII  XLIX = 123  49 = 74
Since, 74 = LXXIV
Therefore, CXXIII  XLIX = LXXIV 
Example 4: Find the Sum of MCCLXVIII and CXXIII Roman Numerals.
Solution:
MCCLXVIII = 1000 + 200 + 60 + 8 = 1268 and CXXIII = 100 + 20 + 3 = 123
Now, MCCLXVIII + CXXIII = 1268 + 123 = 1391
Since, MCCCXCI = 1000 + 300 + 90 + 1 = 1391
Therefore, the sum of MCCLXVIII and CXXIII roman numerals is MCCCXCI
