$15 \div 3 + 8 =$
$9 \times 2 - 5 =$
$24 \div 6 + 10 =$
答案与解析（供教师或家长参考）：
$3 \times 4 - 5 = 12 - 5 = 7$
$6 + 8 \div 2 = 6 + 4 = 10$
$9 \times 3 - 10 = 27 - 10 = 17$
$12 \div 3 + 7 = 4 + 7 = 11$
$5 \times 2 + 15 = 10 + 15 = 25$
$24 \div 4 - 3 = 6 - 3 = 3$
$18 \div 6 + 11 = 3 + 11 = 14$
$7 \times 2 - 8 = 14 - 8 = 6$
$30 \div 5 + 9 = 6 + 9 = 15$
$4 \times 6 - 5 = 24 - 5 = 19$
$16 \div 8 + 12 = 2 + 12 = 14$
$2 \times 9 + 3 = 18 + 3 = 21$
$27 \div 9 - 1 = 3 - 1 = 2$
$20 \div 4 + 13 = 5 + 13 = 18$
$6 \times 3 - 7 = 18 - 7 = 11$
$35 \div 5 + 6 = 7 + 6 = 13$
$8 \times 1 - 3 = 8 - 3 = 5$
$15 \div 3 + 8 = 5 + 8 = 13$
$9 \times 2 - 5 = 18 - 5 = 13$
$24 \div 6 + 10 = 4 + 10 = 14$
希望这些题目能帮助学生在乘除加减的混合运算上取得进步！
