一、口算。（每题1分，共27分）
$67 + 18 =$ $44×5 =$ $50×20 =$
$13×30 =$ $72÷2 =$ $23×3 =$
$85 - 70 =$ $4×200 =$ $80 + 12 =$
$47×3 =$ $26×10 =$ $8×15 =$
$29×20 =$ $91 - 68 =$ $48 + 37 =$
$140÷7 =$ $49×3 =$ $7×11 =$
$400 - 18 =$ $78÷2 =$ $57 + 33 =$
$700×6 =$ $120×3 =$ $20×48 =$
$81 - 39 =$ $55÷5 =$ $8×47 =$

85 220 1000
390 36 69
15 800 92
141 260 120
580 23 85
20 147 77
382 39 90
4200 360 960
42 11 376

二、用竖式计算，带*的要验算。（带*的每题3.5分，其余每题3分，共28分）
$72×15$ $28×32$ $39×26$
$48×58$ $88×16$ *$45×13$
$58×60$ $59×22$ *$60×24$
