## Solved Examples

To better understand how to use the 4×4 determinant calculator, let’s work through a couple of examples:

### Example 1:

Consider the following 4×4 matrix:

```
[2 0 6 9]
[0 0 4 0]
[3 0 0 5]
[0 0 -1 0]
```

Let’s find the determinant of this matrix.

**Solution:** The determinant of the 4×4 square matrix is:

```
|2 0 6 9|
|0 0 4 0|
|3 0 0 5|
|0 0 -1 0| = 0
```

Therefore, the determinant of this matrix is 0.

### Example 2:

Now, let’s consider another 4×4 matrix:

```
[-1 5 6 9]
[ 0 4 7 0]
[ 3 -2 0 5]
[ 0 1 -1 -7]
```

We will calculate the determinant of this matrix.

**Solution:** The determinant of the 4×4 matrix is:

```
|-1 5 6 9|
| 0 4 7 0|
| 3 -2 0 5|
| 0 1 -1 -7| = -485
```

Hence, the determinant of this matrix is -485.
