Project Euler Problem 6: Sum Square Difference
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 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.
