### Topic: Sum square difference

### Problem Statement:

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+3...+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.
