Пошаговое объяснение:
1) 64 + 16 + 8 + 12 = (64 + 16) + (8 + 12) = 80 + 20 = 100
2) 52 - (30 + 12) = 52 - 12 - 30 = 40 - 30 = 10
3) 100 - (25 + 25) = 100 - 50 = 50
4) 100 - (37 + 20) = 100 - 20 - 37 = 80 - 37 = 43
5) 67 + 14 + 3 + 16 = (67 + 3) + (14 + 16) = 70 + 30 = 100
6) (41 + 9) - 30 = 50 - 30 = 20
