2 The sum of the squares of the first ten natural numbers is,
3 1^2 + 2^2 + ... + 10^2 = 385
4 The square of the sum of the first ten natural numbers is,
5 (1 + 2 + ... + 10)^2 = 552 = 3025
6 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.
