一、口算。
$13×3=$ $60÷6=$ $93 - 29=$
$68 + 17=$ $370 + 60=$ $130 - 80=$
$22×3=$ $18÷6=$ $93÷3=$
$650 - 90=$ $70 - 27=$ $36÷7=$
$6×6=$ $88÷2=$ $12×4=$
$41×2=$ $72 - 48=$ $62÷9=$
$10÷5=$ $3×5=$ $27 + 34=$
$320 + 90=$ $1400 - 700=$ $330 - 80=$
$13×3=$ $60÷6=$ $93 - 29=$
$68 + 17=$ $370 + 60=$ $130 - 80=$
$22×3=$ $18÷6=$ $93÷3=$
$650 - 90=$ $70 - 27=$ $36÷7=$
$6×6=$ $88÷2=$ $12×4=$
$41×2=$ $72 - 48=$ $62÷9=$
$10÷5=$ $3×5=$ $27 + 34=$
$320 + 90=$ $1400 - 700=$ $330 - 80=$

二、用竖式计算,带*的要验算。

答案
解:
1. $610 - 258 = 352$
$\begin{array}{r}610 \\-258 \\\hline352\end{array}$
2. $482 + 164 = 646$
$\begin{array}{r}482 \\+164 \\\hline646\end{array}$
3. $637 + 159 = 796$
$\begin{array}{r}637 \\+159 \\\hline796\end{array}$
验算:
$\begin{array}{r}796 \\-159 \\\hline637\end{array}$
4. $412 - 163 = 249$
$\begin{array}{r}412 \\-163 \\\hline249\end{array}$
5. $425 + 296 = 721$
$\begin{array}{r}425 \\+296 \\\hline721\end{array}$
6. $912 - 768 = 144$
$\begin{array}{r}912 \\-768 \\\hline144\end{array}$
验算:
$\begin{array}{r}144 \\+768 \\\hline912\end{array}$
1. $610 - 258 = 352$
$\begin{array}{r}610 \\-258 \\\hline352\end{array}$
2. $482 + 164 = 646$
$\begin{array}{r}482 \\+164 \\\hline646\end{array}$
3. $637 + 159 = 796$
$\begin{array}{r}637 \\+159 \\\hline796\end{array}$
验算:
$\begin{array}{r}796 \\-159 \\\hline637\end{array}$
4. $412 - 163 = 249$
$\begin{array}{r}412 \\-163 \\\hline249\end{array}$
5. $425 + 296 = 721$
$\begin{array}{r}425 \\+296 \\\hline721\end{array}$
6. $912 - 768 = 144$
$\begin{array}{r}912 \\-768 \\\hline144\end{array}$
验算:
$\begin{array}{r}144 \\+768 \\\hline912\end{array}$
