Subtract $10$ from $8$ .

$[\begin{array}{c} - 2 & 6 + 15 & - 3 + 9 \\ - 8 + 14 & 4 + 7 & 0 + 7 \end{array}] + [\begin{array}{c} - 7 & 5 & - 5 \\ 6 & 5 & - 9 \end{array}]$

Add $6$ and $15$ .

$[\begin{array}{c} - 2 & 21 & - 3 + 9 \\ - 8 + 14 & 4 + 7 & 0 + 7 \end{array}] + [\begin{array}{c} - 7 & 5 & - 5 \\ 6 & 5 & - 9 \end{array}]$

Add $- 3$ and $9$ .

$[\begin{array}{c} - 2 & 21 & 6 \\ - 8 + 14 & 4 + 7 & 0 + 7 \end{array}] + [\begin{array}{c} - 7 & 5 & - 5 \\ 6 & 5 & - 9 \end{array}]$

Add $- 8$ and $14$ .

$[\begin{array}{c} - 2 & 21 & 6 \\ 6 & 4 + 7 & 0 + 7 \end{array}] + [\begin{array}{c} - 7 & 5 & - 5 \\ 6 & 5 & - 9 \end{array}]$

Add $4$ and $7$ .

$[\begin{array}{c} - 2 & 21 & 6 \\ 6 & 11 & 0 + 7 \end{array}] + [\begin{array}{c} - 7 & 5 & - 5 \\ 6 & 5 & - 9 \end{array}]$

Add $0$ and $7$ .

$[\begin{array}{c} - 2 & 21 & 6 \\ 6 & 11 & 7 \end{array}] + [\begin{array}{c} - 7 & 5 & - 5 \\ 6 & 5 & - 9 \end{array}]$

Step 3

Add the corresponding elements.

$[\begin{array}{c} - 2 - 7 & 21 + 5 & 6 - 5 \\ 6 + 6 & 11 + 5 & 7 - 9 \end{array}]$
