Addition Without Regrouping Using Expanded Form Worksheet

Problem Description:

The task involves solving addition problems using the expanded form method. The expanded form breaks down numbers into their place values (tens and ones) to simplify the addition process. Each problem requires breaking the numbers into tens and ones, adding them separately, and then combining the results.

Solution:

#### Problem 1:
Addition: \( 43 + 25 \)

1. Expanded Form:
- \( 43 = 40 + 3 \)
- \( 25 = 20 + 5 \)

2. Add Tens:
- \( 40 + 20 = 60 \)

3. Add Ones:
- \( 3 + 5 = 8 \)

4. Combine Results:
- \( 60 + 8 = 68 \)

Answer: \( 68 \)

#### Problem 2:
Addition: \( 35 + 24 \)

1. Expanded Form:
- \( 35 = 30 + 5 \)
- \( 24 = 20 + 4 \)

2. Add Tens:
- \( 30 + 20 = 50 \)

3. Add Ones:
- \( 5 + 4 = 9 \)

4. Combine Results:
- \( 50 + 9 = 59 \)

Answer: \( 59 \)

#### Problem 3:
Addition: \( 23 + 16 \)

1. Expanded Form:
- \( 23 = 20 + 3 \)
- \( 16 = 10 + 6 \)

2. Add Tens:
- \( 20 + 10 = 30 \)

3. Add Ones:
- \( 3 + 6 = 9 \)

4. Combine Results:
- \( 30 + 9 = 39 \)

Answer: \( 39 \)

---

#### Problem 4:
Addition: \( 62 + 33 \)

1. Expanded Form:
- \( 62 = 60 + 2 \)
- \( 33 = 30 + 3 \)

2. Add Tens:
- \( 60 + 30 = 90 \)

3. Add Ones:
- \( 2 + 3 = 5 \)

4. Combine Results:
- \( 90 + 5 = 95 \)

Answer: \( 95 \)

---

#### Problem 5:
Addition: \( 73 + 13 \)

1. Expanded Form:
- \( 73 = 70 + 3 \)
- \( 13 = 10 + 3 \)

2. Add Tens:
- \( 70 + 10 = 80 \)

3. Add Ones:
- \( 3 + 3 = 6 \)

4. Combine Results:
- \( 80 + 6 = 86 \)

Answer: \( 86 \)

---

#### Problem 6:
Addition: \( 51 + 17 \)

1. Expanded Form:
- \( 51 = 50 + 1 \)
- \( 17 = 10 + 7 \)

2. Add Tens:
- \( 50 + 10 = 60 \)

3. Add Ones:
- \( 1 + 7 = 8 \)

4. Combine Results:
- \( 60 + 8 = 68 \)

Answer: \( 68 \)

---

Final Answers:

1. \( 68 \)
2. \( 59 \)
3. \( 39 \)
4. \( 95 \)
5. \( 86 \)
6. \( 68 \)

\[
\boxed{68, 59, 39, 95, 86, 68}
\]
