    题型：数学计算
    解:
          2.8*5.5+(0.2*1.1+3.6*1.8)*2+(0.15*2.25+1.6*0.6)*2+2.8*3+(3.6*0.3+2.2*1.6)+3.02*1.2+1.2+0.6*1.6+0.6*1.8
        =2.8*5.5+6.7*2+(0.15*2.25+1.6*0.6)*2+2.8*3+(3.6*0.3+2.2*1.6)+3.02*1.2+1.2+0.6*1.6+0.6*1.8
        =2.8*5.5+6.7*2+1.2975*2+2.8*3+(3.6*0.3+2.2*1.6)+3.02*1.2+1.2+0.6*1.6+0.6*1.8
        =2.8*5.5+6.7*2+1.2975*2+2.8*3+4.6+3.02*1.2+1.2+0.6*1.6+0.6*1.8
        =15.4+6.7*2+1.2975*2+2.8*3+4.6+3.02*1.2+1.2+0.6*1.6+0.6*1.8
        =15.4+13.4+1.2975*2+2.8*3+4.6+3.02*1.2+1.2+0.6*1.6+0.6*1.8
        =15.4+13.4+2.595+2.8*3+4.6+3.02*1.2+1.2+0.6*1.6+0.6*1.8
        =15.4+13.4+2.595+8.4+4.6+3.02*1.2+1.2+0.6*1.6+0.6*1.8
        =15.4+13.4+2.595+8.4+4.6+3.624+1.2+0.6*1.6+0.6*1.8
        =15.4+13.4+2.595+8.4+4.6+3.624+1.2+0.96+0.6*1.8
        =15.4+13.4+2.595+8.4+4.6+3.624+1.2+0.96+1.08
        =28.8+2.595+8.4+4.6+3.624+1.2+0.96+1.08
        =31.395+8.4+4.6+3.624+1.2+0.96+1.08
        =39.795+4.6+3.624+1.2+0.96+1.08
        =44.395+3.624+1.2+0.96+1.08
        =48.019+1.2+0.96+1.08
        =49.219+0.96+1.08
        =50.179+1.08
        =51.259
    答案:2.8*5.5+(0.2*1.1+3.6*1.8)*2+(0.15*2.25+1.6*0.6)*2+2.8*3+(3.6*0.3+2.2*1.6)+3.02*1.2+1.2+0.6*1.6+0.6*1.8=51.259
