Hitunglah 1. 53+(67-24)= 2. 85+(14-6)= 3. 59-(37+18)= 4. 45-(18+12)= 5. 18+(76-27)= 6. 45-(67+29)= 7. -75+(83-26)= 8. -32-(71+29)= 9. 29+(86-68)= 10. -99-(28-9)

1. 53+(43) = 96
2. 85+(8) = 93
3. 59-(55) = 4
4. 45-(30) = 15
5. 18+(49)= 67
6. 45-(96) = -51
7. -75+57 = -18
8. -32-(100) = -132
9. 29+18 = 47
10. -99-(19) = -118

1. 53-(37+18)= 53-(55) = -2
2. 85+(14-6)= 85+(8)= 93
3. 59-(37+38)=59-(75)= -16
4. 45-(18+12)=45-(18)= 27
5. 18+(76-27)=18+(49)=67
6. 45-(67+29)=45-(96)=-51
7. -75+(83-26)=-75-(57)=-132
8.-32-(71+39)=-32-(110)=-142
9. 29+(86-68)=29+18=47
10. -99-(28-9)=-99-(19)=-118

semoga membantu :)
