Пошаговое объяснение:
№1
-28 : 7 + 8 * (-9) + 63 = -13
1) -28 : 7 = -4
2) 8 * (-9) = -72
3) -4 + (-72) = -4 - 72 = -76
4) -76 + 63 = -13
№2
(-66 + 58 - 13) : 7 * (-10) = 30
1) -66 + 58 = -8
2) -8 - 13 = -21
3) -21 : 7 = -3
4) -3 * (-10) = 30
№3
-30 : (-2 + (-10) * 6 + 52) = 3
1) -10 * 6 = -60
2) -2 + (-60) = -2 - 60 = -62
3) -62 + 52 = -10
4) -30 : (-10) = 3
№4
20 : (-33 - 4 * (-7)) - 47 = -51
1) 4 * (-7) = -28
2) -33 - (-28) = -33 + 28 = -5
3) 20 : (-5) = -4
4) -4 - 47 = -51
№5
-19 + 7 * (-13 - 10 : (-2)) = -75
1) 10 : (-2) = -5
2) -13 - (-5) = -13 + 5 = -8
3) 7 * (-8) = -56
4) -19 + (-56) = -19 - 56 = -75
№6
3 * (-12 + 12 : 2) - 35 = -53
1) 12 : 2 = 6
2) -12 + 6 = -6
3) 3 * (-6) = -18
4) -18 - 35 = -53
