看图列式。列式:
直接写出得数6.2﹣3.8= 100×3.3= 2.14+3.86= 0.35÷0.7=5.02÷0.01= 7.4+6= 2﹣0.7+1.3= 2.5×0.8÷2.5=
口算.7.5+9.2= 9﹣2.7= 16﹣0.9= 2.6×0.3= 4.5÷0.9=8.5×10= 5.2÷0.2= 1.2×6= 7.9÷0.1= 7.6×4=4.5÷3= 0.65÷0.1= (1.5+0.25)×4= 3×0.2×0.5= 12﹣6.5﹣3.5=
口算. 8.4+3.2= 7﹣1.2= 1.93+0.8= 4.6+3.4=0×358= 4.2×10÷100= 5÷100= 7×4﹣4×6=
口算. 35.7+14.8= 24.8﹣14.5= 17﹣14.5= 287+138= 657﹣154=3.65×10= 9.05÷10= 30﹣19.2= 25÷10﹣25÷10= 4.2﹣4.2×0=34.5×10+55= 0÷25+2.5= 8.65﹣2.3﹣1.65= 0.01×100+100=
看谁算得又对又快.7﹣5.32= 0.25+0.75= 4.23×100= 125×8+500=0.75+0.25﹣0.75+0.25= 0.28+0.62= 5÷100= 9.1×10=
