Determinant of a 2x2 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

2 makeMatrix([["a","b"],["c","d"]])

The determinant of a 2x2 matrix can be computed the following way:

printSimpleMatrixDet(HINT_MAT) = matrix2x2DetHint(HINT_MAT)

In this specific case,

printSimpleMatrixDet(MAT) = matrix2x2DetHint(MAT)


                        = SOLN
