$25 + 16 =$ $30×5 =$ $100 - 37 =$ $15×3 =$
$40 - 18 =$ $1000 + 600 =$ $202×4 =$ $21×5 =$
$11×50 =$ $15×5 =$ $906÷3 =$ $84÷6 =$
$48÷4 =$ $75÷5 =$ $\frac{1}{8} + \frac{3}{8} =$ $\frac{7}{10} - \frac{2}{10} =$

答案： $25 + 16 = 41$
$30 × 5 = 150$
$100 - 37 = 63$
$15 × 3 = 45$
$40 - 18 = 22$
$1000 + 600 = 1600$
$202 × 4 = 808$
$21 × 5 = 105$
$11 × 50 = 550$
$15 × 5 = 75$
$906 ÷ 3 = 302$
$84 ÷ 6 = 14$
$48 ÷ 4 = 12$
$75 ÷ 5 = 15$
$\frac{1}{8} + \frac{3}{8} = \frac{4}{8} = \frac{1}{2}$
$\frac{7}{10} - \frac{2}{10} = \frac{5}{10} = \frac{1}{2}$
