1. $-4 \times 32 + 6$

- Multiply first: $-4 \times 32 = -128$
- Then add: $-128 + 6 = -122$

✔ Answer: $-122$

---

2. $3 \times (-12) \div 6$

- Multiply: $3 \times (-12) = -36$
- Divide: $-36 \div 6 = -6$

✔ Answer: $-6$

---

3. $4(13 - 6)$

- Parentheses: $13 - 6 = 7$
- Multiply: $4 \times 7 = 28$

✔ Answer: $28$

---

4. $8 - 4(2 + 7) \div 12$

- Parentheses: $2 + 7 = 9$
- Multiplication: $4 \times 9 = 36$
- Division: $36 \div 12 = 3$
- Subtraction: $8 - 3 = 5$

✔ Answer: $5$

---

5. $(6 + 2) - 15 \div 5 \times 2$

- Parentheses: $6 + 2 = 8$
- Division: $15 \div 5 = 3$
- Multiplication: $3 \times 2 = 6$
- Subtraction: $8 - 6 = 2$

✔ Answer: $2$

---

6. $42 \div (-6) + 5$

- Division: $42 \div (-6) = -7$
- Addition: $-7 + 5 = -2$

✔ Answer: $-2$

---

7. $-64 \div 4(2 - 6)$

- Parentheses: $2 - 6 = -4$
- Now: $-64 \div 4 \times (-4)$
- Division: $-64 \div 4 = -16$
- Multiplication: $-16 \times (-4) = 64$

✔ Answer: $64$

> Note: The expression is interpreted as $(-64) \div 4 \times (-4)$, not $-64 \div [4(-4)]$, since multiplication and division are left to right.

---

8. $4(-12 + 6) \div 3$

- Parentheses: $-12 + 6 = -6$
- Multiply: $4 \times (-6) = -24$
- Divide: $-24 \div 3 = -8$

✔ Answer: $-8$

---

9. $-12 \div 4 - 3 \times 2$

- Division: $-12 \div 4 = -3$
- Multiplication: $3 \times 2 = 6$
- Subtraction: $-3 - 6 = -9$

✔ Answer: $-9$

---

10. $-6 \times 8 - (4 + 2) + 72 \div (-8)$

- Multiplication: $-6 \times 8 = -48$
- Parentheses: $4 + 2 = 6$
- Division: $72 \div (-8) = -9$
- Now: $-48 - 6 + (-9) = -48 - 6 - 9 = -63$

✔ Answer: $-63$

---

11. $6 + (-14) \div 2 - (-8)$

- Division: $(-14) \div 2 = -7$
- Now: $6 + (-7) - (-8)$
- Simplify: $6 - 7 + 8 = -1 + 8 = 7$

✔ Answer: $7$

---

12. $9 \div 3 + 7 \times 4 \div 2$

- Division: $9 \div 3 = 3$
- Multiplication: $7 \times 4 = 28$
- Division: $28 \div 2 = 14$
- Addition: $3 + 14 = 17$

✔ Answer: $17$

---

13. $12 \div (-6) + 5 \times 3$

- Division: $12 \div (-6) = -2$
- Multiplication: $5 \times 3 = 15$
- Addition: $-2 + 15 = 13$

✔ Answer: $13$

---

14. $-4(1 + 5) \div 6 - (42 + 5)$

- Parentheses: $1 + 5 = 6$, $42 + 5 = 47$
- Multiply: $-4 \times 6 = -24$
- Division: $-24 \div 6 = -4$
- Subtraction: $-4 - 47 = -51$

✔ Answer: $-51$

---

15. $7(5 + 3) \div 4(9 - 2)$

- Parentheses: $5 + 3 = 8$, $9 - 2 = 7$
- Multiply: $7 \times 8 = 56$
- Now: $56 \div 4 \times 7$
- Division: $56 \div 4 = 14$
- Multiplication: $14 \times 7 = 98$

✔ Answer: $98$

> Important note: This expression is interpreted as:
> $$
> \frac{7 \times (5+3)}{4} \times (9-2)
> $$
> Since multiplication and division are done left to right.
