Make sure that the the number of columns in the 1 st one equals the number of rows in the 2 nd one. Since we are multiplying 2 square matrices of the same order, we don’t need to check the compatibility in this case. To understand the general pattern of multiplying two matrices, think “rows hit columns and fill up rows”.
