Child's handwritten math worksheet focusing on addition and subtraction using tens and ones, with place value charts and examples.

Problem Analysis:

The image contains three sections of problems related to place value, addition with carrying, and subtraction with borrowing. Let's solve each section step by step.

---

Section Q.1: Write the Standard Form

The task is to convert the given descriptions (e.g., "6 tens + 0 ones") into their standard numerical form.

#### Problems:
1. 6 tens + 0 ones
- 6 tens = 60
- 0 ones = 0
- Total: \( 60 + 0 = 60 \)
- Answer: 60

2. 9 tens + 6 ones
- 9 tens = 90
- 6 ones = 6
- Total: \( 90 + 6 = 96 \)
- Answer: 96

3. 4 tens + 3 ones
- 4 tens = 40
- 3 ones = 3
- Total: \( 40 + 3 = 43 \)
- Answer: 43

4. 6 tens + 0 ones
- 6 tens = 60
- 0 ones = 0
- Total: \( 60 + 0 = 60 \)
- Answer: 60

5. 2 tens + 6 ones
- 2 tens = 20
- 6 ones = 6
- Total: \( 20 + 6 = 26 \)
- Answer: 26

#### Final Answers for Q.1:
- 6 tens + 0 ones = 60
- 9 tens + 6 ones = 96
- 4 tens + 3 ones = 43
- 6 tens + 0 ones = 60
- 2 tens + 6 ones = 26

Section Q.2: Add Ones and Tens with Carry

The task is to perform addition with carrying over when necessary.

#### Problems:
1. 67 + 45
- Ones place: \( 7 + 5 = 12 \) → Write 2, carry 1
- Tens place: \( 6 + 4 + 1 (\text{carry}) = 11 \)
- Total: 112
- Answer: 112

2. 84 + 79
- Ones place: \( 4 + 9 = 13 \) → Write 3, carry 1
- Tens place: \( 8 + 7 + 1 (\text{carry}) = 16 \)
- Total: 163
- Answer: 163

3. 87 + 56
- Ones place: \( 7 + 6 = 13 \) → Write 3, carry 1
- Tens place: \( 8 + 5 + 1 (\text{carry}) = 14 \)
- Total: 143
- Answer: 143

4. 77 + 56
- Ones place: \( 7 + 6 = 13 \) → Write 3, carry 1
- Tens place: \( 7 + 5 + 1 (\text{carry}) = 13 \)
- Total: 133
- Answer: 133

5. 49 + 86
- Ones place: \( 9 + 6 = 15 \) → Write 5, carry 1
- Tens place: \( 4 + 8 + 1 (\text{carry}) = 13 \)
- Total: 135
- Answer: 135

6. 68 + 67
- Ones place: \( 8 + 7 = 15 \) → Write 5, carry 1
- Tens place: \( 6 + 6 + 1 (\text{carry}) = 13 \)
- Total: 135
- Answer: 135

7. 66 + 46
- Ones place: \( 6 + 6 = 12 \) → Write 2, carry 1
- Tens place: \( 6 + 4 + 1 (\text{carry}) = 11 \)
- Total: 112
- Answer: 112

8. 87 + 59
- Ones place: \( 7 + 9 = 16 \) → Write 6, carry 1
- Tens place: \( 8 + 5 + 1 (\text{carry}) = 14 \)
- Total: 146
- Answer: 146

#### Final Answers for Q.2:
- 67 + 45 = 112
- 84 + 79 = 163
- 87 + 56 = 143
- 77 + 56 = 133
- 49 + 86 = 135
- 68 + 67 = 135
- 66 + 46 = 112
- 87 + 59 = 146

Section Q.3: Subtract with Borrow

The task is to perform subtraction with borrowing when necessary.

#### Problems:
1. 64 - 27
- Ones place: \( 4 < 7 \), so borrow 1 from the tens place.
- New tens place: \( 6 - 1 = 5 \)
- New ones place: \( 4 + 10 = 14 \)
- \( 14 - 7 = 7 \)
- Tens place: \( 5 - 2 = 3 \)
- Total: 37
- Answer: 37

2. 75 - 47
- Ones place: \( 5 < 7 \), so borrow 1 from the tens place.
- New tens place: \( 7 - 1 = 6 \)
- New ones place: \( 5 + 10 = 15 \)
- \( 15 - 7 = 8 \)
- Tens place: \( 6 - 4 = 2 \)
- Total: 28
- Answer: 28

3. 87 - 69
- Ones place: \( 7 < 9 \), so borrow 1 from the tens place.
- New tens place: \( 8 - 1 = 7 \)
- New ones place: \( 7 + 10 = 17 \)

- Ones place: \( 8 < 9 \), so borrow 1 from the tens place.
- New tens place: \( 7 - 1 = 6 \)
- New ones place: \( 8 + 10 = 18 \)
- \( 18 - 9 = 9 \)
- Tens place: \( 6 - 2 = 4 \)
- Total: 49
- Answer: 49

6. 65 - 29
- Ones place: \( 5 < 9 \), so borrow 1 from the tens place.
- New tens place: \( 6 - 1 = 5 \)
