# Python Math: Calculate the difference between the squared sum and the sum of squared of first n natural numbers

## Python Math: Exercise-11 with Solution

Write a Python program to calculate the difference between the squared sum of the first n natural numbers and the sum of squared first n natural numbers.(default value of number=2).

**Sample Solution**:

**Python Code:**

```
def sum_difference(n=2):
sum_of_squares = 0
square_of_sum = 0
for num in range(1, n+1):
sum_of_squares += num * num
square_of_sum += num
square_of_sum = square_of_sum ** 2
return square_of_sum - sum_of_squares
print(sum_difference(12))
```

Sample Output:

5434
