text: # 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.
