`100` written as a Roman numeral is `C`.

`[Wikipedia]` `100` is the sum of the first nine prime numbers, as well as the sum of two prime numbers (47 + 53, 17 +83, 3 + 97, 41 + 59), and the sum of the cubes of the first four integers (1^3 + 2^3 + 3^3 + 4^3). Also, 2^6 + 6^2 = `100`, thus it is a Leyland number. [A Leyland number is a number of the form x^y + y^x, where x and y are integers greater than 1. This is the first time MathBabbler documented a Leyland number.]
