  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.
