Matrix Multiplication?

Question

X, Y, Z are matrix

I know that matrix multiplication is associative (XY)Z=X(YZ)

so just to make sure can you put any order so for example XYZ=XZY or YXZ etc..?

Answer 1

matrix multiplication is not commutative, so XYZ does not equal XZY or YXZ or any other combination..

Answer 2

by definition, matrix multiplication is not commutative

so generally, XY is not the same as YX

Answer 3

matrics multiplication is not commutative.
