1. Вычисления:
- \( 72 : 8 + 25 = 9 + 25 = 34 \)
- \( 64 : 8 - 8 = 8 - 8 = 0 \)
- \( 100 - 56 : 8 = 100 - 7 = 93 \)
- \( 51 - 16 : 8 = 51 - 2 = 49 \)
- \( 32 : 8 : 2 = 4 : 2 = 2 \)
- \( 48 - 24 : 8 = 48 - 3 = 45 \)
- \( (65 - 25) : 8 = 40 : 8 = 5 \)
- \( 48 : 8 + 48 = 6 + 48 = 54 \)
Ответ: 34, 0, 93, 49, 2, 45, 5, 54.
