    作业：求算式 276.48*1*0.648649+10.5*(8.8*0.38324+(11/12)*4.4*(0.648649-0.48324)*0.5+(1/12)*0.5*4.4*(0.648649-0.48324)) 的值.
    题型：数学计算
    解:
          276.48*1*0.648649+10.5*(8.8*0.38324+(11/12)*4.4*(0.648649-0.48324)*0.5+(1/12)*0.5*4.4*(0.648649-0.48324))
        =276.48*1*0.648649+10.5*(8.8*0.38324+0.916667*4.4*(0.648649-0.48324)*0.5+(1/12)*0.5*4.4*(0.648649-0.48324))
        =276.48*1*0.648649+10.5*(8.8*0.38324+0.916667*4.4*0.165409*0.5+(1/12)*0.5*4.4*(0.648649-0.48324))
        =276.48*1*0.648649+10.5*(8.8*0.38324+0.916667*4.4*0.165409*0.5+0.083333*0.5*4.4*(0.648649-0.48324))
        =276.48*1*0.648649+10.5*(8.8*0.38324+0.916667*4.4*0.165409*0.5+0.083333*0.5*4.4*0.165409)
        =276.48*1*0.648649+10.5*3.736412
        =276.48*0.648649+10.5*3.736412
        =179.338476+10.5*3.736412
        =179.338476+39.232326
        =218.570802
    答案:276.48*1*0.648649+10.5*(8.8*0.38324+(11/12)*4.4*(0.648649-0.48324)*0.5+(1/12)*0.5*4.4*(0.648649-0.48324))=218.570802
