216一4x6÷3的脱式 =216-24÷3 =216-8 =208

(1)15xx÷(15+u5)×14=15xx÷5x×14=ux×14=44x(4)78x+5xx÷(u4x-47x)=78x+5xx÷5x=78x+1x=79x(u)u4x÷(1448-14×1x1)=u4x÷(1448-1414)=u4x÷1x=4x(4)(48+84)×(97-77)=1u4×4x=4x4x

0.4×125×25×0.8 =(0.4×25)×(125×0.8) =10×100=1000 1.25×(8+10) =1.25×8+1.25×10 =10+12.5=22.5 9123-(123+8.8) =9123-123-8.8 =9000-8.8 =8991.2 1.24×8.3+8.3×1.76 =8.3×(1.24+1.76) =8.3×3=24.9 9999×1001 =9999×(1000+1) =9999×...

35×(26÷2+7) =35×(13+7) =35×20 =700 1680÷[4×(13-9)] =1680÷(4×4) =1680÷16 =105
