Problem Analysis:
The task involves completing a series of addition problems where one of the addends is always 8, and the other addend ranges from 0 to 8. The goal is to compute each sum and fill in the missing values.
Step-by-Step Solution:
1.
8 + 0 = ?
- Adding 0 to any number results in the same number.
- Therefore, \( 8 + 0 = 8 \).
2.
8 + 1 = ?
- Adding 1 to 8 means moving one step forward on the number line.
- Therefore, \( 8 + 1 = 9 \).
3.
8 + 2 = ?
- Adding 2 to 8 means moving two steps forward on the number line.
- Therefore, \( 8 + 2 = 10 \).
4.
8 + 3 = ?
- Adding 3 to 8 means moving three steps forward on the number line.
- Therefore, \( 8 + 3 = 11 \).
5.
8 + 4 = ?
- Adding 4 to 8 means moving four steps forward on the number line.
- Therefore, \( 8 + 4 = 12 \).
6.
8 + 5 = ?
- Adding 5 to 8 means moving five steps forward on the number line.
- Therefore, \( 8 + 5 = 13 \).
7.
8 + 6 = ?
- Adding 6 to 8 means moving six steps forward on the number line.
- Therefore, \( 8 + 6 = 14 \).
8.
8 + 7 = ?
- Adding 7 to 8 means moving seven steps forward on the number line.
- Therefore, \( 8 + 7 = 15 \).
9.
8 + 8 = ?
- Adding 8 to 8 means doubling 8.
- Therefore, \( 8 + 8 = 16 \).
Final Answers:
\[
\begin{aligned}
&8 + 0 = 8 \\
&8 + 1 = 9 \\
&8 + 2 = 10 \\
&8 + 3 = 11 \\
&8 + 4 = 12 \\
&8 + 5 = 13 \\
&8 + 6 = 14 \\
&8 + 7 = 15 \\
&8 + 8 = 16 \\
\end{aligned}
\]
Explanation:
Each problem involves simple addition, where the first addend is always 8, and the second addend increases sequentially from 0 to 8. By understanding the basic principle of addition and counting forward on the number line, we can easily compute each sum.
Final Answer:
\[
\boxed{8, 9, 10, 11, 12, 13, 14, 15, 16}
\]
