Ф.И. Карточка 5 27+(9.6-25) + 72:9= 100-(63+ 27 - 58): 4= (31-30) (63: 7 + 64:8)= (6.4+3.8) : (70 – 69)= (42-18): (60 – 36) + 99= 56: (15-7) + 4 = 9. (5 + 4) : 9 = 60-(23+22): 5-6-3 +35= (23-19) 4 +18 : 3 + (8 + 22) = 13+(60-6): 9 = 42:6+7.4 = 72+ (40-4) : 9 = 63:7+ (20-5) - (9 + 6) = 18+36:9+6.8-50 = 5. (4+3) + 19 - 10 = (18+36): 9+6.8-40 = 42:7+ (19+11): 5-2-6= (82-82): 2.7+7.7- (63-27)=

Краткое пояснение: Решаем примеры, соблюдая порядок действий: сначала в скобках, затем умножение и деление, и в конце сложение и вычитание.
- 27 + (9 ⋅ 6 - 25) + 72 ÷ 9 = 27 + (54 - 25) + 8 = 27 + 29 + 8 = 56 + 8 = 64
- 100 - (63 + 27 - 58) ÷ 4 = 100 - (90 - 58) ÷ 4 = 100 - 32 ÷ 4 = 100 - 8 = 92
- (31 - 30) ⋅ (63 ÷ 7 + 64 ÷ 8) = 1 ⋅ (9 + 8) = 1 ⋅ 17 = 17
- (6 ⋅ 4 + 3 ⋅ 8) ÷ (70 - 69) = (24 + 24) ÷ 1 = 48 ÷ 1 = 48
- (42 - 18) ÷ (60 - 36) + 99 = 24 ÷ 24 + 99 = 1 + 99 = 100
- 56 ÷ (15 - 7) + 4 = 56 ÷ 8 + 4 = 7 + 4 = 11
- 9 ⋅ (5 + 4) ÷ 9 = 9 ⋅ 9 ÷ 9 = 81 ÷ 9 = 9
- 60 - (23 + 22) ÷ 5 - 6 ⋅ 3 + 35 = 60 - 45 ÷ 5 - 18 + 35 = 60 - 9 - 18 + 35 = 51 - 18 + 35 = 33 + 35 = 68
- (23 - 19) ⋅ 4 + 18 ÷ 3 + (8 + 22) = 4 ⋅ 4 + 6 + 30 = 16 + 6 + 30 = 22 + 30 = 52
- 13 + (60 - 6) ÷ 9 = 13 + 54 ÷ 9 = 13 + 6 = 19
- 42 ÷ 6 + 7 ⋅ 4 = 7 + 28 = 35
- 72 + (40 - 4) ÷ 9 = 72 + 36 ÷ 9 = 72 + 4 = 76
- 63 ÷ 7 + (20 - 5) - (9 + 6) = 9 + 15 - 15 = 24 - 15 = 9
- 18 + 36 ÷ 9 + 6 ⋅ 8 - 50 = 18 + 4 + 48 - 50 = 22 + 48 - 50 = 70 - 50 = 20
- 5 ⋅ (4 + 3) + 19 - 10 = 5 ⋅ 7 + 19 - 10 = 35 + 19 - 10 = 54 - 10 = 44
- (18 + 36) ÷ 9 + 6 ⋅ 8 - 40 = 54 ÷ 9 + 48 - 40 = 6 + 48 - 40 = 54 - 40 = 14
- 42 ÷ 7 + (19 + 11) ÷ 5 - 2 ⋅ 6 = 6 + 30 ÷ 5 - 12 = 6 + 6 - 12 = 12 - 12 = 0
- (82 - 82) ÷ 2 ⋅ 7 + 7 ⋅ 7 - (63 - 27) = 0 ÷ 2 ⋅ 7 + 7 ⋅ 7 - 36 = 0 + 49 - 36 = 49 - 36 = 13
