Step-by-step Solution
Let's solve each expression step by step.
1. **First Row:**
- \( 7 \times 5 + 4 + 2 - 5 \)
\[
= 35 + 4 + 2 - 5 = 36
\]
- \( 12 \times 2 - 4 \div 2 \)
\[
= 24 - 2 = 22
\]
2. **Second Row:**
- \( 5 + 32 \div 8 - 14 \)
\[
= 5 + 4 - 14 = -5
\]
- \( 35 \div 5 + 12 \div 6 \)
\[
= 7 + 2 = 9
\]
3. **Third Row:**
- \( 25 + 15 \div 3 + 9 \)
\[
= 25 + 5 + 9 = 39
\]
- \( 2 + 42 \div 7 - 5 \)
\[
= 2 + 6 - 5 = 3
\]
4. **Fourth Row:**
- \( 30 \div 5 - 7 + 16 \)
\[
= 6 - 7 + 16 = 15
\]
- \( 6 + 3 + 8 \times 9 \)
\[
= 6 + 3 + 72 = 81
\]
5. **Fifth Row:**
- \( 5 + 72 \div 9 - 3 \)
\[
= 5 + 8 - 3 = 10
\]
- \( 36 \div 7 + 5 - 12 \)
\[
\approx 5.14 + 5 - 12 \approx -1.86 \quad (\text{or } -\frac{13}{7} \text{ if exact})
\]
6. **Sixth Row:**
- \( 51 - 6 \times 2 - 14 \)
\[
= 51 - 12 - 14 = 25
\]
- \( 4 + 48 - 3 \times 3 \)
\[
= 4 + 48 - 9 = 43
\]
Now, summarizing the results:
\[
\begin{array}{|c|c|}
\hline
\text{Expression} & \text{Result} \\
\hline
7 \times 5 + 4 + 2 - 5 & 36 \\
12 \times 2 - 4 \div 2 & 22 \\
\hline
5 + 32 \div 8 - 14 & -5 \\

6 + 3 + 8 \times 9 & 81 \\
\hline
5 + 72 \div 9 - 3 & 10 \\
36 \div 7 + 5 - 12 & -1.86 \\
\hline
51 - 6 \times 2 - 14 & 25 \\
4 + 48 - 3 \times 3 & 43 \\
\hline
\end{array}
