Document Summary
Provide a generalization to each of the key terms listed in this section. Adding matrices (cid:18) a d b e i. + f d + h(cid:19) e + k f + l(cid:19) + h c + i c c f c + g (cid:18)a b d(cid:19) +(cid:18)e f (cid:19) +(cid:18) g g h(cid:19) = (cid:18)a + e l(cid:19) = (cid:18)a + g a + d. + e c + f d + j d e f a b c h k j. Subtracting matrices (cid:18)a b d(cid:19) (cid:18)e f(cid:19) (cid:18)g h (cid:18)a a b c b e c g g h(cid:19) = (cid:18)a e l(cid:19) = (cid:18)a g a d. E c f d e f d j d k c c j i. What is a zero matrix is when a matrix with the elements that are all 0, which an example of one can be the following: (cid:18)0 0.
