Jawaban:
1. (20 + 16)+(-18) = 20+(16+(-18) = 18
2. (-73+27)+(-30) = -73+(27+(-30)) = -70
3. -51+(-62+55) = (-51+(-62))+55 = -58
4. 38+(-68+(-39)) = (38+(-68))+(-39) = -69
5. (82+(-44))+(-15) = 82+(-44+(-15)) = 23
6. (-14*8)*(-7) = -14*(8*(-7)) = 784
7. (-20*(-13))*(-3) = -20*(-13*(-3)) = -780
8. 8*(-7*11) = (8*(-7))*11 = -616
9. -10*(21*(-4)) = (-10*21)*-4 = 840
10. (-22*(-3))*15 = -22*(-3*15) = 990
