15. \( 2 \times 1 \)
16. \( 4 \times 6 \)

Solutions:

1. \( 2 \times 2 = 4 \)
- Multiply 2 by 2: \( 2 + 2 = 4 \).

2. \( 3 \times 6 = 18 \)
- Multiply 3 by 6: \( 3 + 3 + 3 + 3 + 3 + 3 = 18 \).

3. \( 3 \times 7 = 21 \)
- Multiply 3 by 7: \( 3 + 3 + 3 + 3 + 3 + 3 + 3 = 21 \).

4. \( 4 \times 4 = 16 \)
- Multiply 4 by 4: \( 4 + 4 + 4 + 4 = 16 \).

5. \( 2 \times 8 = 16 \)
- Multiply 2 by 8: \( 8 + 8 = 16 \).

6. \( 3 \times 5 = 15 \)
- Multiply 3 by 5: \( 3 + 3 + 3 + 3 + 3 = 15 \).

7. \( 3 \times 2 = 6 \)
- Multiply 3 by 2: \( 3 + 3 = 6 \).

8. \( 4 \times 1 = 4 \)
- Multiply 4 by 1: \( 4 \).

9. \( 2 \times 7 = 14 \)
- Multiply 2 by 7: \( 7 + 7 = 14 \).

10. \( 2 \times 5 = 10 \)
- Multiply 2 by 5: \( 5 + 5 = 10 \).

11. \( 4 \times 2 = 8 \)
- Multiply 4 by 2: \( 4 + 4 = 8 \).

12. \( 3 \times 4 = 12 \)
- Multiply 3 by 4: \( 3 + 3 + 3 + 3 = 12 \).

13. \( 4 \times 8 = 32 \)
- Multiply 4 by 8: \( 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 = 32 \).

14. \( 2 \times 4 = 8 \)
- Multiply 2 by 4: \( 4 + 4 = 8 \).

15. \( 2 \times 1 = 2 \)
- Multiply 2 by 1: \( 2 \).

16. \( 4 \times 6 = 24 \)
- Multiply 4 by 6: \( 4 + 4 + 4 + 4 + 4 + 4 = 24 \).

Final Answers:

\[
\boxed{
\begin{array}{cccc}
4 & 18 & 21 & 16 \\
16 & 15 & 6 & 4 \\
14 & 10 & 8 & 12 \\
32 & 8 & 2 & 24 \\
\end{array}
}
\]

Each problem has been solved by repeated addition or direct multiplication, ensuring accuracy.
