照样子写算式。
$(40 + 8)\times25$
$= 40\times25 + 8\times25$
$125\times(8 + 80)$
$=$
$36\times(100 + 50)$
$=$
$24\times(2 + 10)$
$=$
$86\times(1000 - 2)$
$=$
$63\times43 + 57\times63$
$=$
$93\times6 + 93\times4$
$=$
$325\times113 - 325\times13$
$=$
$28\times18 - 8\times28$
$=$
$125\times26 - 125\times18$
$=$
