The sum of the squares of the first ten natural numbers is, 1^2 + 2^2 + ... + 10^2 = 385
The square of the sum of the first ten natural numbers is, (1 + 2 + ... + 10)^2 = 55^2 = 3025
Hence the difference between the square of the sum and the sum of the squares is 3025 โ 385 = 2640. Find the difference between the sum of the squares of the first one hundred natural numbers and the square of the sum.
