pake caranya!!!!!

Answer 1

1. -70 - (35 + -25) = -70 - 10 = -60
2. -65 - (-73 - 28) = -65 - (-101) = -166
3. 80 + (-45 - (-40)) = 80 + -85 = -5
4. 75 + (-43 + 46) = 75 + 3 = 78
5. -53 - (-35 + (-49)) = -53 - (-84) = -127
6. (-85 + (-70)) - (-35) = -115 - (-35) = -150
7. (-25 - (-35)) + (-20) = -60 + -20 = -80
8. -75 + -35 + -18 = -128
9. 83 - (-73) - (-42) = 10 - (-42) = -32
10. 53 - (-38) + -55 = 15 - (-55) = -40
