The higher roman numerals precede the lower numerals resulting in the correct translation of CXLV Roman Numerals. In this article, we will explain how to convert CXLV Roman numerals in the correct number translation.
 CXLV = C + XL + V
 CXLV = 100 + 40 + 5
 CXLV = 145
How to Write CXLV Roman Numerals?
The numerical value of CXLV 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.
 CXLV = C + (L  X) + V = 100 + (50  10) + 5 = 145
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 CXLV = C + XL + V = 100 + 40 + 5 = 145
Therefore, the numerical value of CXLV roman numerals is 145.

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: XI, X > I, so XI = X + I = 10 + 1 = 11
 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: II = I + I = 1 + 1 = 2
 The same letter cannot be used more than three times in succession.
