Add and subtract 10 worksheet with a table for finding missing numbers.

Problem Description:

The task is to fill in the missing numbers in a table by adding or subtracting 10 from the given numbers. The table has three columns:
1. 10 less: Subtract 10 from the central number.
2. Central Number: The given number.
3. 10 more: Add 10 to the central number.

Solution Approach:

For each row:
- 10 less: Subtract 10 from the central number.
- 10 more: Add 10 to the central number.

Let's solve it step by step for each row.

Row-by-Row Calculation:

#### Row 1:
- Central Number: 40
- 10 less: \( 40 - 10 = 30 \)
- 10 more: \( 40 + 10 = 50 \)

#### Row 2:
- Central Number: 70
- 10 less: \( 70 - 10 = 60 \)
- 10 more: \( 70 + 10 = 80 \)

#### Row 3:
- Central Number: 30
- 10 less: \( 30 - 10 = 20 \)
- 10 more: \( 30 + 10 = 40 \)

#### Row 4:
- Central Number: 80
- 10 less: \( 80 - 10 = 70 \)
- 10 more: \( 80 + 10 = 90 \)

#### Row 5:
- Central Number: 60
- 10 less: \( 60 - 10 = 50 \)
- 10 more: \( 60 + 10 = 70 \)

#### Row 6:
- Central Number: 10
- 10 less: \( 10 - 10 = 0 \)
- 10 more: \( 10 + 10 = 20 \)

#### Row 7:
- Central Number: 50
- 10 less: \( 50 - 10 = 40 \)
- 10 more: \( 50 + 10 = 60 \)

#### Row 8:
- Central Number: 90
- 10 less: \( 90 - 10 = 80 \)
- 10 more: \( 90 + 10 = 100 \)

#### Row 9:
- Central Number: 20
- 10 less: \( 20 - 10 = 10 \)
- 10 more: \( 20 + 10 = 30 \)

#### Row 10:
- Central Number: 35
- 10 less: \( 35 - 10 = 25 \)
- 10 more: \( 35 + 10 = 45 \)

#### Row 11:
- Central Number: 65
- 10 less: \( 65 - 10 = 55 \)
- 10 more: \( 65 + 10 = 75 \)
