#### Section 1: Addition Problems
The first section involves adding numbers to find the sum for each row. We will solve these systematically.

##### Row 1:
$$
\begin{array}{r}
6.5 \\
+3.3 \\
\hline
9.8 \\
\end{array}
$$
- Add the decimal parts: $0.5 + 0.3 = 0.8$.
- Add the whole numbers: $6 + 3 = 9$.
- Combine: $9 + 0.8 = 9.8$.

##### Row 2:
$$
\begin{array}{r}
14 \\
+2.4 \\
\hline
16.4 \\
\end{array}
$$
- Add the decimal parts: $0.0 + 0.4 = 0.4$.
- Add the whole numbers: $14 + 2 = 16$.
- Combine: $16 + 0.4 = 16.4$.

##### Row 3:
$$
\begin{array}{r}
5.0 \\
+1.0 \\
\hline
6.0 \\
\end{array}
$$
- Add the decimal parts: $0.0 + 0.0 = 0.0$.
- Add the whole numbers: $5 + 1 = 6$.
- Combine: $6 + 0.0 = 6.0$.

##### Row 4:
$$
\begin{array}{r}
7.4 \\
+2.8 \\
\hline
10.2 \\
\end{array}
$$
- Add the decimal parts: $0.4 + 0.8 = 1.2$ (carry over 1 to the whole number).
- Add the whole numbers: $7 + 2 + 1 = 10$.
- Combine: $10 + 0.2 = 10.2$.

##### Row 5:
$$
\begin{array}{r}
5.7 \\
+1.3 \\
\hline
7.0 \\
\end{array}
$$
- Add the decimal parts: $0.7 + 0.3 = 1.0$ (carry over 1 to the whole number).
- Add the whole numbers: $5 + 1 + 1 = 7$.
- Combine: $7 + 0.0 = 7.0$.

##### Row 6:
$$
\begin{array}{r}
3.0 \\
+6.5 \\
\hline
9.5 \\
\end{array}
$$
- Add the decimal parts: $0.0 + 0.5 = 0.5$.
- Add the whole numbers: $3 + 6 = 9$.
- Combine: $9 + 0.5 = 9.5$.

##### Row 7:
$$
\begin{array}{r}
1.7 \\
+3.2 \\
\hline
4.9 \\
\end{array}
$$
- Add the decimal parts: $0.7 + 0.2 = 0.9$.
- Add the whole numbers: $1 + 3 = 4$.
- Combine: $4 + 0.9 = 4.9$.

##### Row 8:
$$
\begin{array}{r}
6.4 \\
+2.2 \\
\hline
8.6 \\
\end{array}
$$
- Add the decimal parts: $0.4 + 0.2 = 0.6$.
- Add the whole numbers: $6 + 2 = 8$.
- Combine: $8 + 0.6 = 8.6$.

##### Row 9:
$$
\begin{array}{r}
1.5 \\
+1.3 \\
\hline
2.8 \\
\end{array}
$$
- Add the decimal parts: $0.5 + 0.3 = 0.8$.
- Add the whole numbers: $1 + 1 = 2$.
- Combine: $2 + 0.8 = 2.8$.
