Answer 12

Basically all it is that you are adding two sets of numbers together.
Because i cant the matrix thing for three number, i will only show the top two on the left.\[\left[\begin{matrix}-9 & -1 \\ ? & ?\end{matrix}\right] +\left[\begin{matrix}-2 & 0 \\ ? & ?\end{matrix}\right]=\left[\begin{matrix}-11 & -1 \\ ? & ?\end{matrix}\right]\]
So as you can see
-9+-1=-11
and -1+0=-11

There you go...
