〖1/1算式〗
    作业：求算式 2.58*4.48+4.48+3.14+3.14-(0.54*1.84)-(1.44*1.84)-(0.88*2.15)-(2.88*0.5) 的值.
    题型：数学计算
    解:
          2.58*4.48+4.48+3.14+3.14-(0.54*1.84)-(1.44*1.84)-(0.88*2.15)-(2.88*0.5)
        =2.58*4.48+4.48+3.14+3.14-0.9936-(1.44*1.84)-(0.88*2.15)-(2.88*0.5)
        =2.58*4.48+4.48+3.14+3.14-0.9936-2.6496-(0.88*2.15)-(2.88*0.5)
        =2.58*4.48+4.48+3.14+3.14-0.9936-2.6496-1.892-(2.88*0.5)
        =2.58*4.48+4.48+3.14+3.14-0.9936-2.6496-1.892-1.44
        =11.5584+4.48+3.14+3.14-0.9936-2.6496-1.892-1.44
        =16.0384+3.14+3.14-0.9936-2.6496-1.892-1.44
        =19.1784+3.14-0.9936-2.6496-1.892-1.44
        =22.3184-0.9936-2.6496-1.892-1.44
        =21.3248-2.6496-1.892-1.44
        =18.6752-1.892-1.44
        =16.7832-1.44
        =15.3432
    答案:2.58*4.48+4.48+3.14+3.14-(0.54*1.84)-(1.44*1.84)-(0.88*2.15)-(2.88*0.5)=15.3432
