The product from multiplying matrices is always??

OpenStudy (anonymous):

The product of a matrix with m rows and n columns times a matrix with n rows and p colums is m x p

OpenStudy (anonymous):

So is it commutative, zero property, or identity? Or none of those?

OpenStudy (anonymous):

Oh, that's different. OK lemme see

OpenStudy (anonymous):

Not commutative, order makes a difference.

OpenStudy (anonymous):

What does "zero property" mean, "identity" too?

OpenStudy (anonymous):

Thats what im stumped on...it doesnt make sense to me at all

OpenStudy (anonymous):

Well, it is certainly not always the identity or zero..

OpenStudy (anonymous):

I'd say, none of the three choices you have given.

OpenStudy (richyw):

I'd say zero property because any matrix times the zero matrix gives you the zero matrix.

OpenStudy (richyw):

oh wait that's not the zero property though.

OpenStudy (anonymous):

so its none?

OpenStudy (anonymous):

Only three choices?

OpenStudy (anonymous):

correct
