Answer:
1. 18 + 6 = 6 + 18 → Commutative Property
2. -40 + 40 = 0 → Inverse Property
3. (10+3) + 6 = 10 + (3+6) → Associative Property
4. -15 + 0 = -15 → Identity Property
5. 42 + 0 = 42 → Identity Property
6. -2(5+8) = -10 + (-16) → Distributive Property
7. 30 (1) = 30 → Identity Property
8.[(4)(6)] 2 = 4[(6)(2)] → Associative Property
9. 15 * 0 = 0 → Zero Property
10. (12)(-4) = (-4) 12 → Commutative Property
