8 Составь программу действий и вычисли: a) (24+18):7-0(82-58) + 16.3 = б) 21: (96-89) + (7.4+6).2-56:56 =

1. а) (24 + 18) : 7 - 0 ⋅ (82 - 58) + 16 ⋅ 3 =

   1) 24 + 18 = 42

   2) 42 : 7 = 6

   3) 82 - 58 = 24

   4) 0 ⋅ 24 = 0

   5) 16 ⋅ 3 = 48

   6) 6 - 0 + 48 = 54

2. б) 21 : (96 - 89) + (7 ⋅ 4 + 6) ⋅ 2 - 56 : 56 =

   1) 96 - 89 = 7

   2) 21 : 7 = 3

   3) 7 ⋅ 4 = 28

   4) 28 + 6 = 34

   5) 34 ⋅ 2 = 68

   6) 56 : 56 = 1

   7) 3 + 68 - 1 = 70

Ответ: 54; 70
