To commute or not to commute, that is the question. The 26th segment in a 32-segment lesson focuses on the effect of performing one transformation after another one. The pupils develop the procedure in order to multiply two 2 X 2 matrices and whether the operation is commutative or not. The class continues with addition of matrices and the role of the zero matrix.
