Пошаговое объяснение:

1) (+18) + (-982) = -964

2) -678 + 678 = 0

3) 0 - (+981) = -981

4) (-15) + 846 = 831

5) -507 - 0 = -507

6) (-464) + (-464) = -928

7) -217 - (-689) = 472

8) 0 + (-436) = -436

9) 71 - (-193) = 264

10) +118 - (+118) = 0

11) (+654) + 346 = 1000

12) 268 - (+413) = -145

Answer 2

Let's solve each of the expressions step by step:

1. (+18) + (-982): (+18) + (-982) = -964

2. -678 + 678: -678 + 678 = 0

3. 0 - (+981): 0 - (+981) = -981

4. (-15) + 846: (-15) + 846 = 831

5. -507 - 0: -507 - 0 = -507

6. (-464) + (-464): (-464) + (-464) = -928

7. -217 - (-689): -217 - (-689) = 472

8. 0 + (-436): 0 + (-436) = -436

9. 71 - (-193): 71 - (-193) = 264

10. +118 - (+118): +118 - (+118) = 0

11. (+654) + 346: (+654) + 346 = 1000

12. 268 - (+413): 268 - (+413) = -145
