# Sum of square Course Challenge: Intro to Programming

## sumSquareDifference.js

The sum of the squares of the first ten natural numbers is 1^{2} + 2^{2} + 3^{2} + ... + 10 ^{2} = 385.

The square of the sum of the first ten natural numbers is (1 + 2 + 3 + ... + 10)^{2} = 55^{2} = 3025.

Hence the difference between the square of the sum and the sum of the squares of the first ten natural numbers is 3025 − 385 = 2640.

Write the `sumSquareDifference()`

function that takes argument `n`

and returns the difference between the square of the sum and the sum of the squares of first `n`

natural numbers.
