### About the method

To calculate a determinant you need to do the following steps.

- Set the matrix (must be square).
- Reduce this matrix to row echelon form using elementary row operations so that all the elements below diagonal are zero.
- Multiply the main diagonal elements of the matrix - determinant is calculated.

To understand determinant calculation better input any example, choose "very detailed solution" option and examine the solution.
