XC Roman Numerals
XC Roman Numerals can be written as numbers by combining the transformed roman numerals i.e. XC = (C  X) = (100  10) = 90. The higher roman numerals precede the lower numerals resulting in the correct translation of XC Roman Numerals. In this article, we will explain how to convert XC Roman numerals in the correct number translation.
 XC = (C  X)
 XC = (100  10)
 XC = 90
How to Write XC Roman Numerals?
The numerical value of XC 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.
 XC = (C  X) = (100  10) = 90
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 XC = 90
Therefore, the numerical value of XC roman numerals is 90.

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: ML, M > L, so ML = M + L = 1000 + 50 = 1050
 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: XXX = X + X + X = 10 + 10 + 10 = 30
 The same letter cannot be used more than three times in succession.

XC Roman Numerals Examples

Example 1: Find the Product of Roman Numerals XC and VII.
Solution:
XC = 90 and VII = 7
Now, XC × VII = 90 × 7 = 630
Since, DCXXX = 600 + 30 = 630
Therefore, XC × VII = DCXXX 
Example 2: Find the Sum of CLXXIII and XC Roman Numerals.
Solution:
CLXXIII = 100 + 70 + 3 = 173 and XC = 90
Now, CLXXIII + XC = 173 + 90 = 263
Since, CCLXIII = 200 + 60 + 3 = 263
Therefore, the sum of CLXXIII and XC roman numerals is CCLXIII 
Example 3: Find the Difference Between XC and LII.
Solution:
Roman Numeral XC is equal to 90 and LII is 52.
Now, XC  LII = 90  52 = 38
Since, 38 = XXXVIII
Therefore, XC  LII = XXXVIII
