The sum of the squares of the first ten natural numbers is,12 + 22 + … + 102 = 385
The square of the sum of the first ten natural numbers is,(1 + 2 + … + 10)2 = 552 = 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.
