Пошаговое объяснение:
7.1.
40 : (24 : 3) + 8
Первое действие: 24 : 3 = 8
Второе действие: 40 : 8 = 5
Третье действие: 5 + 8 = 13.
7.2.
16 · (9 : 3 + 17) - 80
Первое действие: 9 : 3 = 3
Второе действие: 3 + 17 = 20
Третье действие: 16 · 20 = 320
Четвёртое действие: 320 - 80 = 240
7.3.
(24 - 3 · 5) - 5 · 6
Первое действие: 3 · 5 =15
Второе действие: 24 - 15 = 9
Третье действие: 5 · 6 = 30
Четвёртое действие: 9 - 30 = -21
7.4.
(26 - 6 · 3) - 6 · 4
Первое действие: 6 · 3 = 18
Второе действие: 26 - 18 = 8
Третье действие: 6 · 4 = 24
Четвёртое действие: 8 - 24 = -16
Удачи!
