〖1/1算式〗
    作业：求算式 (78.67+36.00)×1×3.1%+90.00×1×0.5×3.1% 的值.
    题型：数学计算
    解:
          (78.67+36.00)×1×3.1%+90.00×1×0.5×3.1%
        =114.67×1×3.1%+90.00×1×0.5×3.1%
        =114.67×1×0.031+90.00×1×0.5×3.1%
        =114.67×1×0.031+90.00×1×0.5×0.031

        =114.67×0.031+90×1×0.5×0.031
        =3.55477+90×1×0.5×0.031
        =3.55477+90×0.5×0.031
        =3.55477+45×0.031
        =3.55477+1.395
        =4.94977
    答案:(78.67+36.00)×1×3.1%+90.00×1×0.5×3.1%=4.94977
