Решим данные примеры:

1. • $$0:9 = 0$$
   • $$0:24 = 0$$
   • $$0 \cdot 33 = 0$$

   Ответ: 0; 0; 0.

2. • $$60-(16-9)\cdot4 = 60 - 7\cdot4 = 60 - 28 = 32$$
   • $$56:(13-5)+9 = 56:8+9 = 7+9 = 16$$
   • $$42+72:9 = 42+8 = 50$$
   • $$60-54:6 = 60-9 = 51$$
   • $$87:(85+2)-1 = 87:87-1 = 1-1 = 0$$
   • $$100-32:(16+16) = 100-32:32 = 100-1 = 99$$
   • $$90-(48-18)\cdot1 = 90-30\cdot1 = 90-30 = 60$$
   • $$93-7\cdot(15-8) = 93 - 7\cdot7 = 93-49 = 44$$
   • $$8\cdot9+64:8 = 72 + 8 = 80$$

   Ответ: 32; 16; 50; 51; 0; 99; 60; 44; 80.
