1. 直接写出得数。
$103 - 48 =$ $92×7 =$ $60 - 43 =$ $7×7×4 =$
$153 + 57 =$ $65 - 59 =$ $120÷5 =$ $9×9 - 29 =$
$310×9 =$ $80 + 740 =$ $9×102 =$ $480÷(57 - 54) =$
$271×2 =$ $46×8 =$ $39×3 =$ $540÷9÷2 =$
$110 - 27 =$ $178÷2 =$ $37 + 39 =$ $24×6÷8 =$
$78÷6 =$ $53×3 =$ $102÷3 =$ $36 + 57 - 27 =$
$26×7 =$ $99÷9 =$ $6×403 =$ $(72 + 3)×8 =$
$18×0 =$ $34×5 =$ $770×2 =$ $(50 + 88)÷2 =$
$103 - 48 =$ $92×7 =$ $60 - 43 =$ $7×7×4 =$
$153 + 57 =$ $65 - 59 =$ $120÷5 =$ $9×9 - 29 =$
$310×9 =$ $80 + 740 =$ $9×102 =$ $480÷(57 - 54) =$
