Math worksheet for practicing addition and subtraction by 10.

Problem Analysis:

The task requires us to fill in the missing numbers in a table. The table has three columns:
1. 10 Less: This column should contain numbers that are 10 less than the number in the middle column.
2. Middle Column: This column contains given numbers.
3. 10 More: This column should contain numbers that are 10 more than the number in the middle column.

Step-by-Step Solution:

We will calculate the values for each row based on the given middle column numbers.

#### Row 1:
- Middle column: 20
- 10 Less: \( 20 - 10 = 10 \)
- 10 More: \( 20 + 10 = 30 \)

#### Row 2:
- Middle column: 52
- 10 Less: \( 52 - 10 = 42 \)
- 10 More: \( 52 + 10 = 62 \)

#### Row 3:
- Middle column: 11
- 10 Less: \( 11 - 10 = 1 \)
- 10 More: \( 11 + 10 = 21 \)

#### Row 4:
- Middle column: 36
- 10 Less: \( 36 - 10 = 26 \)
- 10 More: \( 36 + 10 = 46 \)

#### Row 5:
- Middle column: 84
- 10 Less: \( 84 - 10 = 74 \)
- 10 More: \( 84 + 10 = 94 \)

#### Row 6:
- Middle column: 67
- 10 Less: \( 67 - 10 = 57 \)
- 10 More: \( 67 + 10 = 77 \)

#### Row 7:
- Middle column: 70
- 10 Less: \( 70 - 10 = 60 \)
- 10 More: \( 70 + 10 = 80 \)

#### Row 8:
- Middle column: 45
- 10 Less: \( 45 - 10 = 35 \)
- 10 More: \( 45 + 10 = 55 \)

#### Row 9:
- Middle column: 98
- 10 Less: \( 98 - 10 = 88 \)
- 10 More: \( 98 + 10 = 108 \)

Final Table:

Here is the completed table:

| 10 Less | Middle Column | 10 More |
|---------|---------------|---------|
| 10 | 20 | 30 |
| 42 | 52 | 62 |
| 1 | 11 | 21 |
| 26 | 36 | 46 |
| 74 | 84 | 94 |
| 57 | 67 | 77 |
| 60 | 70 | 80 |
| 35 | 45 | 55 |
| 88 | 98 | 108 |

Final Answer:

\[
\boxed{
\begin{array}{|c|c|c|}
\hline
10 \text{ Less} & \text{Middle Column} & 10 \text{ More} \\
\hline
10 & 20 & 30 \\
42 & 52 & 62 \\
1 & 11 & 21 \\
26 & 36 & 46 \\
74 & 84 & 94 \\
57 & 67 & 77 \\
60 & 70 & 80 \\
35 & 45 & 55 \\
88 & 98 & 108 \\
\hline
\end{array}
}
