Determinant of a 3x3 matrix

makeMatrix(randRange(-2, 5, DIM, DIM)) matrixDet(MAT) "\\textbf " + randFromArray("ABCDEF")

PRETTY_MAT_ID = printSimpleMatrix(MAT)

What is the determinant of PRETTY_MAT_ID?

SOLN

3 makeMatrix([["a","b","c"],["d","e","f"],["g","h","i"]])


                        det(PRETTY_MAT_ID)
                        = printSimpleMatrixDet(MAT)
                        = SOLN
