####
Left Column:
1.
8 + (-6) =
- Adding a negative number is the same as subtracting its positive counterpart.
- \( 8 + (-6) = 8 - 6 = 2 \)
-
Answer: \( 2 \)
2.
0 + 10 =
- Adding any number to zero gives that number.
- \( 0 + 10 = 10 \)
-
Answer: \( 10 \)
3.
(-9) + (-3) =
- Adding two negative numbers results in a negative sum.
- \( (-9) + (-3) = -(9 + 3) = -12 \)
-
Answer: \( -12 \)
4.
6 + (-4) =
- Adding a negative number is the same as subtracting its positive counterpart.
- \( 6 + (-4) = 6 - 4 = 2 \)
-
Answer: \( 2 \)
5.
8 + 1 =
- Adding a positive number to another positive number.
- \( 8 + 1 = 9 \)
-
Answer: \( 9 \)

- Adding a positive number to a negative number.
- \( (-2) + 8 = 8 - 2 = 6 \)
-
Answer: \( 6 \)
8.
(-7) + 3 =
- Adding a positive number to a negative number.
- \( (-7) + 3 = -(7 - 3) = -4 \)
-
Answer: \( -4 \)
9.
7 + (-1) =
- Adding a negative number is the same as subtracting its positive counterpart.
- \( 7 + (-1) = 7 - 1 = 6 \)
-
Answer: \( 6 \)
10.
(-5) + 8 =
- Adding a positive number to a negative number.
- \( (-5) + 8 = 8 - 5 = 3 \)
-
Answer: \( 3 \)

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