1) 9x7 + 6x3= 2) 6x4 + 7x8= 3) 5x4 + 18:2= 4) 7x6 - 24:3= 5) 5x9 - 14:2=

Решение:

1. \( 9 \times 7 + 6 \times 3 = 63 + 18 = 81 \)
2. \( 6 \times 4 + 7 \times 8 = 24 + 56 = 80 \)
3. \( 5 \times 4 + 18 \div 2 = 20 + 9 = 29 \)
4. \( 7 \times 6 - 24 \div 3 = 42 - 8 = 34 \)
5. \( 5 \times 9 - 14 \div 2 = 45 - 7 = 38 \)

Ответ: 1) 81, 2) 80, 3) 29, 4) 34, 5) 38.
