If $A = \displaystyle\left[\begin{array}{ccc} -3 &-3 &4 \cr -3 &-1 &-1 \cr 3 &-3 &-2 \cr \end{array}\right] \qquad \text{and}\qquad B = \displaystyle\left[\begin{array}{ccc} 1 &3 &0 \cr 2 &1 &2 \cr 1 &0 &0 \cr \end{array}\right]$ Then

$2A+B =$

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