782. Решите примеры. (100-34)·7 (91-45)·9 (25+39)-4 (12+49)-5 (48+16)-8 (72-27)-6 (31-18)-9 (27+34)-6 (84-59)-7

Решение:

1. (100 - 34) · 7 = 66 · 7 = 462

2. (91 - 45) · 9 = 46 · 9 = 414

3. (25 + 39) - 4 = 64 - 4 = 60

4. (12 + 49) - 5 = 61 - 5 = 56

5. (48 + 16) - 8 = 64 - 8 = 56

6. (72 - 27) - 6 = 45 - 6 = 39

7. (31 - 18) - 9 = 13 - 9 = 4

8. (27 + 34) - 6 = 61 - 6 = 55

9. (84 - 59) - 7 = 25 - 7 = 18

Ответ: 462, 414, 60, 56, 56, 39, 4, 55, 18
