Question

Can a matrix with dimensions of 4 X 5 be added to another matrix with dimensions 5 X 3?

Answer 1

nope

Answer 2

it can be multiplied though

Answer 3

for addition, you need the same size matrices.

for multiplication you need the 'inners to be the same'

so in this case (4x5)(5x3) since the inners are the same, then it can be multiplied. another interesting this is that the outers is what the end matrix size will be i.e. 4x3
