Practical Example

Let’s walk through a simple example using a 2×2 matrix.

Example Matrix:

[4726]\begin{bmatrix} 4 & 7 \\ 2 & 6 \end{bmatrix}[42​76​]

Steps:

1. Select 2 × 2 Matrix
2. Enter the values: 4, 7, 2, 6
3. Click Calculate

Result:

The determinant value is: (4×6)−(7×2)=24−14=10(4 × 6) − (7 × 2) = 24 − 14 = 10(4×6)−(7×2)=24−14=10

The tool instantly displays 10.0000 as the determinant.

This same process works just as easily for 3×3 matrices, saving you from lengthy manual calculations.
