If $A = \displaystyle\left[\begin{array}{rrr} -3 &1 &-3 \cr 3 &4 &0 \cr -3 &2 &-1 \cr \end{array}\right]$ and $I$ is the $3 \times 3$ identity matrix, then

$A I =$

$\left.\vphantom{\begin{array}{c}\!\strut\\\!\strut\\\!\strut\\\!\strut\\\end{array}}\right[$				$\left.\vphantom{\begin{array}{c}\!\strut\\\!\strut\\\!\strut\\\!\strut\\\end{array}}\right]$

and

$I A =$

$\left.\vphantom{\begin{array}{c}\!\strut\\\!\strut\\\!\strut\\\!\strut\\\end{array}}\right[$				$\left.\vphantom{\begin{array}{c}\!\strut\\\!\strut\\\!\strut\\\!\strut\\\end{array}}\right]$
