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.
