Краткое пояснение: Решаем примеры по порядку действий: сначала в скобках, затем умножение и деление, в конце сложение и вычитание.
- Пример 1: 720 ⋅ 9 – 385 : 5 ⋅ (1 029 – 980)
- 1) 1 029 – 980 = 49
- 2) 720 ⋅ 9 = 6 480
- 3) 385 : 5 = 77
- 4) 77 ⋅ 49 = 3 773
- 5) 6 480 – 3 773 = 2 707
- Пример 2: (811 + 4 189) : 1 000 ⋅ 317 – 600
- 1) 811 + 4 189 = 5 000
- 2) 5 000 : 1 000 = 5
- 3) 5 ⋅ 317 = 1 585
- 4) 1 585 – 600 = 985
- Пример 3: 3 100 : (67 ⋅ 28 – 592 ⋅ 3) + 2 599
- 1) 67 ⋅ 28 = 1 876
- 2) 592 ⋅ 3 = 1 776
- 3) 1 876 – 1 776 = 100
- 4) 3 100 : 100 = 31
- 5) 31 + 2 599 = 2 630
- Пример 4: 371 ⋅ 50 – 8 ⋅ (42 ⋅ 100 – 616 ⋅ 4)
- 1) 42 ⋅ 100 = 4 200
- 2) 616 ⋅ 4 = 2 464
- 3) 4 200 – 2 464 = 1 736
- 4) 8 ⋅ 1 736 = 13 888
- 5) 371 ⋅ 50 = 18 550
- 6) 18 550 – 13 888 = 4 662
- Пример 5: (95 ⋅ 63 – 94 ⋅ 56 + 279) : 1 000
- 1) 95 ⋅ 63 = 5 985
- 2) 94 ⋅ 56 = 5 264
- 3) 5 985 – 5 264 = 721
- 4) 721 + 279 = 1 000
- 5) 1 000 : 1 000 = 1
- Пример 6: (53 040 – 52 584) ⋅ 90 + 58 960
- 1) 53 040 – 52 584 = 456
- 2) 456 ⋅ 90 = 41 040
- 3) 41 040 + 58 960 = 100 000
Ответ: 2 707; 985; 2 630; 4 662; 1; 100 000
