Jawab:
1) - 83 + {( - 17) - (26)} = -83 + (- 43)
= -83 - 43 = -126
2) 35 +(-43) - (-25) = 35 - 43 + 25
= -8 + 25 = 17
3) 27 -(-43) + (-12) = 27 + 43 - 12
= 70 - 12 = 58
4) 64 + (38 - (-30)) = 64 + ( (38 + 30)
= 64 + 68 = 132
5) 17 + ((-53) + (-30)) = 17 + (-53 -30)
= 17 + (-83)
= 17 - 83 = -66
6) -53 + ((-43) + (-33)) = -53 + (-43 - 33)
= -53 + (-76)
= -53 - 76 = -129
7) -40 -(65 -(-39)) = -40 - (65 + 39)
= -40 - (104) = 64
8) -69 + (-30) + (-30) = -69 - 30 -30
= -99 - 30 = -129
