Question

Выполни поразрядное вычитание с переходом через разряд 34-7,63-6,52-5,45-6,71-9,96-8. например 24-7=(20+4)-7=(10+14)-7=10+(14-7)=10+7=17

Answer 1

34 - 7 = (30 + 4) - 7 = (20 + 14) - 7 = 20 + (14 - 7) = 20 + 7 = 27

63 - 6 = (60 + 3) - 6 = (50 + 13) - 6 = 50 + (13 - 6) = 50 + 7 = 57

52 - 5 = (50 + 2) - 5 = (40 + 12) - 5 = 40 + (12 - 5) = 40 + 7 = 47

45 - 6 = (40 + 5) - 6 = (30 + 15) - 6 = 30 + (15 - 6) = 30 + 9 = 39

71 - 9 = (70 + 1) - 9 = (60 + 11) - 9 = 60 + (11 - 9) = 60 + 2 = 62

96 - 8 = (90 + 6) - 8 = (80 + 16) - 8 = 80 + (16 - 8) = 80 + 8 = 88
