# Sum square difference
# Problem 6
# https://projecteuler.net/problem=6
# 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 = 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.
# Answer: 25164150
