请脱式计算,能简算的要简算4.85+3.62+1.38+5.15 [16.7﹣(6.2+9.5)]×8.33.25÷0.25+1.75÷0.25 10.52﹣(3.52﹣1.7)
列竖式计算 38×56= 10﹣5.2= 16.7+5.9= 450×14= 25×12= 68.5﹣47.9=
列竖式计算. ①48×25②20﹣13.8③872÷8.
竖式计算: 34×15= 15.4+7.8= 16.7+6.4=
列竖式计算(打★的要验算). 24×62= 47×29= 7.8+6.4= 7﹣2.5= 536÷8=★562÷4=
用竖式计算(带☆的要验算) 95×78=☆695÷3=☆42×55=816÷4= 4.9+5.3= 7.1﹣6.2=
