What is the following in Arabic numbers CXXVI?

To understand why the answer is 126, it is important to break down the Roman numeral CXXVI into its individual components:

• C represents 100.

• XX represents 20 (with each X corresponding to 10, so X + X = 10 + 10 = 20).

• VI represents 6 (with V as 5 and I as 1, so V + I = 5 + 1 = 6).

When you add these values together:

• 100 (C) + 20 (XX) + 6 (VI) equals 126.

This cumulative process of breaking down Roman numerals is essential in converting them accurately to Arabic numbers. The total of 126 is thus derived from correctly interpreting and summing the individual parts of the numeral, confirming that the final answer is indeed 126.
