Final Answers:

\[
\begin{array}{ll}
\text{Left Column:} & \text{Right Column:} \\
8 + (-6) = 2 & 2 + 7 = 9 \\
0 + 10 = 10 & (-9) + 6 = -3 \\
(-9) + (-3) = -12 & (-1) + 6 = 5 \\
6 + (-4) = 2 & 6 + (-4) = 2 \\
8 + 1 = 9 & 3 + 5 = 8 \\
6 + 6 = 12 & (-5) + (-4) = -9 \\
0 + (-2) = -2 & (-2) + 8 = 6 \\
(-9) + 4 = -5 & (-7) + 3 = -4 \\
6 + 1 = 7 & 7 + (-1) = 6 \\
4 + (-2) = 2 & (-5) + 8 = 3 \\
\end{array}
\]

\boxed{
\begin{array}{ll}
2 & 9 \\
10 & -3 \\
-12 & 5 \\
2 & 2 \\
9 & 8 \\
