以下是一些适合二年级上册学生的乘除加减混合口算题：
$3 \times 4 + 5 = $
$6 \times 2 - 4 = $
$5 \times 3 + 7 = $
$4 \times 6 - 8 = $
$7 + 2 \times 3 = $
$9 - 3 \times 2 = $
$8 \div 2 + 5 = $
$12 \div 3 \times 2 = $
$10 - 5 \times 1 = $
$6 \div 3 + 4 \times 2 = $
$3 \times 5 - 7 = $
$4 \times 2 + 10 = $
$15 \div 5 + 3 = $
$8 \times 1 - 3 = $
$9 + 6 \div 3 = $
$12 - 4 \times 2 = $
$7 \times 2 - 5 \div 5 = $
