We look at row matrices, column matrices, square matrices, diagonal matrices, scalar matrices, identity matrices, and zero matrices. After looking at examples for each, we also figure out what constraints work for elements of each of these matrices.

We first understand when can we compare two matrices (when their order is same) and when we can't (when they have different orders). We then find missing elements from equal matrices. We first solve two problems where two unknowns are there before solving a problem with four unknowns.
