Verified answer

Пошаговое объяснение:

А)

1) |7 + 2²| = |7 + 4| = |11| = 11

2) 4 * 11 = 44

3) 2 + 44 = 46

4) 4 * 2 = 8

5) 5 * 3 = 15

6) 8 + 15 = 23

7) 46 : 23 = 2

В)

1) 4 * (-6) = -24

2) 5 * 2 = 10

3) 2 + (-24) = 2 - 24 = -22

4) -22 - 4 = -26

5) -26 - 22 = -48

6) -48 - 10 = -58

7) -4 - (-58) = -4 + 58 = 54

С)

1) 6 * 2 = 12

2) 12 + 2 = 14

3) 14 - (-6) = 14 + 6 = 20

4) |-18 : 6| = |-3| = 3

5) -5 + 3 = -2

6) 20 * (-2) = -40

D)

1) 1 - 3 = -2

2) -2 - (-2) = -2 + 2 = 0

3) 6 * 0 = 0

4) 2 * (-3) = -6

5) -6 + 3 = -3

6) -3 - 0 = -3
