- Add 6 and 2: \( 6 + 2 = 8 \)
12. \( 8 + 1 = 9 \)
- Add 8 and 1: \( 8 + 1 = 9 \)
#### Row 4:
13. \( 2 + 1 = 3 \)
- Add 2 and 1: \( 2 + 1 = 3 \)
14. \( 6 + 9 = 15 \)
- Add 6 and 9: \( 6 + 9 = 15 \)
15. \( 2 + 7 = 9 \)
- Add 2 and 7: \( 2 + 7 = 9 \)
16. \( 3 + 8 = 11 \)
- Add 3 and 8: \( 3 + 8 = 11 \)
Final Answers:
\[
\begin{array}{cccc}
10 & 7 & 11 & 9 \\
8 & 11 & 13 & 17 \\
12 & 14 & 8 & 9 \\
3 & 15 & 9 & 11 \\
\end{array}
\]
