Answer: 1. 31 + 6 + 25 + 2 = 64 2. -9 + 21 = 12 3. 0 + 9 = 9 4. 2 + (-16) + (-17) = -31 5. 1 + 1 = 2 6. -5 + 0 = -5 7. – 13 + 28 = -3 8. 28 + (-20) = 8 9. – – 2 + 10 = 12 10. – 18 + 18 = 0 Reply
Answer:
1. 31 + 6 + 25 + 2 = 64
2. -9 + 21 = 12
3. 0 + 9 = 9
4. 2 + (-16) + (-17) = -31
5. 1 + 1 = 2
6. -5 + 0 = -5
7. – 13 + 28 = -3
8. 28 + (-20) = 8
9. – – 2 + 10 = 12
10. – 18 + 18 = 0
