        =1/2*9.27*152.028899999999993+9.27*12.33*6.25-100.27-239.7-34.06*6.25-1/2*28.06*6.25^2
        =1/2*9.27*152.028899999999993+9.27*12.33*6.25-100.27-239.7-34.06*6.25-1/2*28.06*39.0625
        =0.5*9.27*152.028899999999993+9.27*12.33*6.25-100.27-239.7-34.06*6.25-1/2*28.06*39.0625
        =4.635*152.028899999999993+9.27*12.33*6.25-100.27-239.7-34.06*6.25-1/2*28.06*39.0625
        =704.653951+9.27*12.33*6.25-100.27-239.7-34.06*6.25-1/2*28.06*39.0625
        =704.653951+114.2991*6.25-100.27-239.7-34.06*6.25-1/2*28.06*39.0625
        =704.653951+714.369375-100.27-239.7-34.06*6.25-1/2*28.06*39.0625
        =704.653951+714.369375-100.27-239.7-212.875-1/2*28.06*39.0625
        =704.653951+714.369375-100.27-239.7-212.875-0.5*28.06*39.0625
        =704.653951+714.369375-100.27-239.7-212.875-14.03*39.0625
        =704.653951+714.369375-100.27-239.7-212.875-548.046875
        =1419.023326-100.27-239.7-212.875-548.046875
        =1318.753326-239.7-212.875-548.046875
        =1079.053326-212.875-548.046875
        =866.178326-548.046875
        =318.131451
    答案:1/2*9.27*12.33^2+9.27*12.33*6.25-100.27-239.7-34.06*6.25-1/2*28.06*6.25^2=318.131451
