Вычисли. 3 ⋅ 9 + 43 9 ⋅ 8 - 32 (34 - 20) : 7 (21 - 15) ⋅ 5 90 - 9 ⋅ 6 42 + 7 ⋅ 4 13 - 4 ⋅ 2 (13 - 4) ⋅ 2

Ответ: 70; 4; 36; 10; 36; 70; 5; 18

1. \[3 \cdot 9 + 43 = 27 + 43 = 70\]
2. \[9 \cdot 8 - 32 = 72 - 32 = 40\]
3. \[(34 - 20) \div 7 = 14 \div 7 = 2\]
4. \[(21 - 15) \cdot 5 = 6 \cdot 5 = 30\]
5. \[90 - 9 \cdot 6 = 90 - 54 = 36\]
6. \[42 + 7 \cdot 4 = 42 + 28 = 70\]
7. \[13 - 4 \cdot 2 = 13 - 8 = 5\]
8. \[(13 - 4) \cdot 2 = 9 \cdot 2 = 18\]
