what is the additive iddentity for 2x4 matrices

OpenStudy (amistre64):

an additive identity is what you add to get the same value. 0 is the identity for addition; 1 is the identity for multiplications; I got no idea at the moment what it is for a matrix; but whatever it is, it makes it equal itself

OpenStudy (anonymous):

it would be a matrix of all 0s.
