Problem Description:

The task involves solving a series of arithmetic problems, including subtraction and addition. Each problem is presented in a vertical format, and we need to compute the results step by step.

Solution:

#### Problem 1:
$$
8289 - 7146
$$
- Align the numbers vertically:
$$
\begin{array}{r}
8289 \\
- 7146 \\
\hline
\end{array}
$$
- Subtract digit by digit from right to left:
- \(9 - 6 = 3\)
- \(8 - 4 = 4\)
- \(2 - 1 = 1\)
- \(8 - 7 = 1\)
- Result:
$$
\boxed{1143}
$$

#### Problem 2:
$$
35716 - 20357
$$
- Align the numbers vertically:
$$
\begin{array}{r}
35716 \\
- 20357 \\
\hline
\end{array}
$$
- Subtract digit by digit from right to left:
- \(6 - 7\): Borrow 1 from the next column (7 becomes 6), so \(16 - 7 = 9\)
- \(1 - 5\): Borrow 1 from the next column (5 becomes 4), so \(11 - 5 = 6\)
- \(6 - 3 = 3\)
- \(5 - 0 = 5\)
- \(3 - 2 = 1\)
- Result:
$$
\boxed{15359}
$$

#### Problem 3:
$$
9736 - 4948
$$
- Align the numbers vertically:
$$
\begin{array}{r}
9736 \\
- 4948 \\
\hline
\end{array}
$$
- Subtract digit by digit from right to left:
- \(6 - 8\): Borrow 1 from the next column (3 becomes 2), so \(16 - 8 = 8\)
- \(2 - 4\): Borrow 1 from the next column (7 becomes 6), so \(12 - 4 = 8\)
- \(6 - 9\): Borrow 1 from the next column (9 becomes 8), so \(16 - 9 = 7\)
- \(8 - 4 = 4\)
- Result:
$$
\boxed{4788}
$$

#### Problem 4:
$$
48985 - 23897
$$
- Align the numbers vertically:
$$
\begin{array}{r}
48985 \\
- 23897 \\
\hline
\end{array}
$$
- Subtract digit by digit from right to left:
- \(5 - 7\): Borrow 1 from the next column (8 becomes 7), so \(15 - 7 = 8\)
- \(7 - 9\): Borrow 1 from the next column (9 becomes 8), so \(17 - 9 = 8\)
- \(8 - 8 = 0\)
- \(8 - 3 = 5\)
- \(4 - 2 = 2\)
- Result:
$$
\boxed{25088}
$$

#### Problem 5:
$$
19375 - 52310
$$
- Align the numbers vertically:
$$
\begin{array}{r}
19375 \\
- 52310 \\
\hline
\end{array}
$$
- Since \(19375 < 52310\), the result will be negative. Compute \(52310 - 19375\) and then apply the negative sign:
- \(5 - 0 = 5\)
- \(7 - 1 = 6\)
- \(3 - 3 = 0\)
- \(9 - 2 = 7\)
- \(5 - 1 = 4\)
- Result of \(52310 - 19375 = 32935\). Therefore:
$$
\boxed{-32935}
$$

#### Problem 6:
$$
342146 + 431264
$$
- Align the numbers vertically:
$$
\begin{array}{r}
342146 \\
+ 431264 \\
\hline
\end{array}
$$
- Add digit by digit from right to left:
- \(6 + 4 = 10\): Write down 0, carry 1
- \(4 + 6 + 1 = 11\): Write down 1, carry 1
- \(1 + 2 + 1 = 4\)
- \(2 + 1 = 3\)
- \(4 + 3 = 7\)
- \(3 + 4 = 7\)
- Result:
$$
\boxed{773410}
$$

#### Problem 7:
$$
457653 + 137246
$$
- Align the numbers vertically:
$$
\begin{array}{r}
457653 \\
+ 137246 \\
\hline
\end{array}
$$
- Add digit by digit from right to left:
- \(3 + 6 = 9\)
- \(5 + 4 = 9\)
- \(6 + 2 = 8\)
- \(7 + 7 = 14\): Write down 4, carry 1
- \(5 + 3 + 1 = 9\)
- \(4 + 1 = 5\)
- Result:
$$
\boxed{594899}
$$

#### Problem 8:
$$
57638 + 28419
$$
- Align the numbers vertically:
$$
\begin{array}{r}
57638 \\
+ 28419 \\
\hline
\end{array}
$$
- Add digit by digit from right to left:
- \(8 + 9 = 17\): Write down 7, carry 1
- \(3 + 1 + 1 = 5\)
- \(6 + 4 = 10\): Write down 0, carry 1
- \(7 + 8 + 1 = 16\): Write down 6, carry 1
- \(5 + 2 + 1 = 8\)
- Result:
$$
\boxed{86057}
$$

#### Problem 9:
$$
29834 + 13975
$$
- Align the numbers vertically:
$$
\begin{array}{r}
29834 \\
+ 13975 \\
\hline
\end{array}
$$
- Add digit by digit from right to left:
- \(4 + 5 = 9\)
- \(3 + 7 = 10\): Write down 0, carry 1
- \(8 + 9 + 1 = 18\): Write down 8, carry 1
- \(9 + 3 + 1 = 13\): Write down 3, carry 1
- \(2 + 1 + 1 = 4\)
- Result:
$$
\boxed{43809}
$$
