    题型：数学计算
    解:
          17.8×2.83+(17.8-9.8)×(3.24-2.83)+(17.8-9.8)×15.6+(19.1-9.8)×0.08+(17.9-9.8)×7.39+(17.9-9.8)×0.63
        =17.8×2.83+8×(3.24-2.83)+(17.8-9.8)×15.6+(19.1-9.8)×0.08+(17.9-9.8)×7.39+(17.9-9.8)×0.63
        =17.8×2.83+8×0.41+(17.8-9.8)×15.6+(19.1-9.8)×0.08+(17.9-9.8)×7.39+(17.9-9.8)×0.63
        =17.8×2.83+8×0.41+8×15.6+(19.1-9.8)×0.08+(17.9-9.8)×7.39+(17.9-9.8)×0.63
        =17.8×2.83+8×0.41+8×15.6+9.3×0.08+(17.9-9.8)×7.39+(17.9-9.8)×0.63
        =17.8×2.83+8×0.41+8×15.6+9.3×0.08+8.1×7.39+(17.9-9.8)×0.63
        =17.8×2.83+8×0.41+8×15.6+9.3×0.08+8.1×7.39+8.1×0.63
        =50.374+8×0.41+8×15.6+9.3×0.08+8.1×7.39+8.1×0.63
        =50.374+3.28+8×15.6+9.3×0.08+8.1×7.39+8.1×0.63
        =50.374+3.28+124.8+9.3×0.08+8.1×7.39+8.1×0.63
        =50.374+3.28+124.8+0.744+8.1×7.39+8.1×0.63
        =50.374+3.28+124.8+0.744+59.859+8.1×0.63
        =50.374+3.28+124.8+0.744+59.859+5.103
        =53.654+124.8+0.744+59.859+5.103
        =178.454+0.744+59.859+5.103
        =179.198+59.859+5.103
        =239.057+5.103
        =244.16
    答案:17.8×2.83+(17.8-9.8)×(3.24-2.83)+(17.8-9.8)×15.6+(19.1-9.8)×0.08+(17.9-9.8)×7.39+(17.9-9.8)×0.63=244.16
