1.a 10 + (-17) - (-5) = 10 - 17 + 5 = -7 + 5 = -2
1.b -8 + (-6) - 9 = -8 - 6 - 9 = -14 - 9 = -23
1.c 12 + (-12) + 8 = 12 - 12 + 8 = 8
1.d 3 - 5 - 11 = -2 - 11 = -13
1.e 6 - 11 + (-30) = 6 - 11 - 30 = -5 - 30 = -35
1.f -13 - 19 + 27 = -32 + 27 = -5

2.a (-50) + 30 - (-28) = -50 + 30 + 28 = -20 + 28 = 8
2.b 75 - 47 - (-19) = 75 - 47 + 19 = 28 + 19 = 47
2.c (- 7 - 8) × 35 = -15 × 35 = -525
2.d - 8 - 9 - (-12) ÷ 4 = -17 - (-3) = -17 + 3 = -14
