# Problem Definition

Available at Sum square difference

The sum of the squares of the first ten natural numbers is,

`12 + 22 + ... + 102 = 385`

The square of the sum of the first ten natural numbers is,

`(1 + 2 + ... + 10)2 = 552 = 3025`

Hence the difference between the sum of the squares of the first ten natural numbers and the square of the sum is 3025-385 = 2640.Find the difference between the sum of the squares of the first one hundred natural numbers and the square of the sum.
