〖1/1算式〗
    作业：求算式 (20+17.3*2.6+16.7*2.1+19.9*2.3+19.3*3+19*5+19.1*5-175)*0.31-2^3.3*0.56+125 的值.
    题型：数学计算
    解:
          (20+17.3*2.6+16.7*2.1+19.9*2.3+19.3*3+19*5+19.1*5-175)*0.31-2^3.3*0.56+125
        =219.22*0.31-2^3.3*0.56+125
        =219.22*0.31-9.849155306759329*0.56+125
        =67.9582-9.849155306759329*0.56+125
        =67.9582-5.515527+125
        =62.442673+125
        =187.442673
    答案:(20+17.3*2.6+16.7*2.1+19.9*2.3+19.3*3+19*5+19.1*5-175)*0.31-2^3.3*0.56+125=187.442673
