    题型：数学计算
    解:
          276.48*1*0.531889+10.5*(8.8*0.48305+(11/12)*4.4*(0.513889-0.48305)*0.5+(1/12)*0.5*4.4*(0.513889-0.48305))
        =276.48*1*0.531889+10.5*(8.8*0.48305+0.916667*4.4*(0.513889-0.48305)*0.5+(1/12)*0.5*4.4*(0.513889-0.48305))
        =276.48*1*0.531889+10.5*(8.8*0.48305+0.916667*4.4*0.030839*0.5+(1/12)*0.5*4.4*(0.513889-0.48305))
        =276.48*1*0.531889+10.5*(8.8*0.48305+0.916667*4.4*0.030839*0.5+0.083333*0.5*4.4*(0.513889-0.48305))
        =276.48*1*0.531889+10.5*(8.8*0.48305+0.916667*4.4*0.030839*0.5+0.083333*0.5*4.4*0.030839)
        =276.48*1*0.531889+10.5*4.318686
        =276.48*0.531889+10.5*4.318686
        =147.056671+10.5*4.318686
        =147.056671+45.346203
        =192.402874
    答案:276.48*1*0.531889+10.5*(8.8*0.48305+(11/12)*4.4*(0.513889-0.48305)*0.5+(1/12)*0.5*4.4*(0.513889-0.48305))=192.402874
