52+27= | 70×50= | 83-57= | 3000+7000= |
91-34= | 65-23= | 60+70= | 86÷2= |
4.直接写得数
30×23= | 80÷4= | 33-18= | 400÷5= |
45+27= | 40×22= | 94-57= | 70×80= |
0÷5= | 41×20= | 480÷2= | 360÷9= |
400÷8= | 210÷7= | $\frac{5}{9}$+$\frac{2}{9}$= | $\frac{7}{10}$-$\frac{4}{10}$= |
$\frac{3}{5}$+$\frac{1}{5}$= | $\frac{5}{9}$-$\frac{3}{9}$= | $\frac{4}{7}$-$\frac{2}{7}$= |
