About the method

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

  1. Set the matrix (must be square).
  2. Reduce this matrix to row echelon form using elementary row operations so that all the elements below diagonal are zero.
  3. 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.
