答案：
1
$16 ÷ 2 = 8$
$40 ÷ 8 = 5$
$27 ÷ 9 = 3$
$81 ÷ 9 = 9$
$36 ÷ 9 = 4$
$24 ÷ 3 = 8$
$24 ÷ 4 = 6$
$32 ÷ 8 = 4$
$56 ÷ 8 = 7$
$24 ÷ 6 = 4$
$72 ÷ 9 = 8$
$25 ÷ 5 = 5$
$42 ÷ 6 = 7$
$27 ÷ 3 = 9$
$8 × 3 = 24$
2
$49 ÷ 7 = 7$
$9 × 6 = 54$
$9 ÷ 3 = 3$
$64 ÷ 8 = 8$
$42 ÷ 7 = 6$
$63 ÷ 9 = 7$
$56 ÷ 7 = 8$
$14 ÷ 2 = 7$
$18 ÷ 2 = 9$
$8 × 6 = 48$
$20 ÷ 5 = 4$
$8 × 7 = 56$
$9 × 4 = 36$
$63 ÷ 7 = 9$
$40 ÷ 5 = 8$
3
$8 × 8 = 64$
$48 ÷ 8 = 6$
$6 × 9 = 54$
$21 ÷ 7 = 3$
$24 ÷ 8 = 3$
$16 ÷ 8 = 2$
$8 × (15 - 8) = 8 × 7 = 56$
$(25 + 23) ÷ 8 = 48 ÷ 8 = 6$
$(63 - 36) ÷ 3 = 27 ÷ 3 = 9$
$8 × 9 + 18 = 72 + 18 = 90$
$(52 - 38) ÷ 7 = 14 ÷ 7 = 2$
$7 × 9 + 7 = 63 + 7 = 70$
$92 - 4 × 8 = 92 - 32 = 60$
$65 + 72 ÷ 9 = 65 + 8 = 73$
$(100 - 80) ÷ 4 = 20 ÷ 4 = 5$
